500 Words Essay On Healthy Food

Healthy food is an essential aspect of a healthy lifestyle. It is not only crucial for maintaining physical health, but it can also have a significant impact on our mental and emotional well-being. Eating a balanced diet that includes a variety of fruits, vegetables, whole grains, and lean proteins can help us feel energised, focused, and happy. But for many people, eating healthy can be a challenge. In a world where fast food and processed snacks are readily available and often more convenient than cooking a meal from scratch, it can be tempting to choose unhealthy options. And with busy schedules and hectic lives, it can be difficult to find the time and energy to plan and prepare healthy meals.

However, the benefits of eating healthy far outweigh the challenges. Not only can it help us maintain a healthy weight and reduce our risk of chronic diseases like heart disease, diabetes, and cancer, but it can also improve our mood, energy levels, and overall quality of life.

My Experience

As I sat down at my desk with a bag of chips and a soda for lunch again, I realised that I had been making unhealthy food choices all week. I had been so busy with work and other obligations that I hadn't taken the time to plan and prepare healthy meals. I decided then and there to make a change. I started by making a grocery list of nutritious, whole foods and meal planning for the week ahead. I also made a commitment to myself to cook at home more often instead of relying on takeout or fast food. It wasn't easy at first, but over time, I started to notice a difference in my energy levels and overall mood. I felt better physically and mentally, and I was able to maintain a healthy weight. Making healthy food choices became a priority for me, and I am now reaping the numerous benefits of a nutritious diet.

One of the key components of a healthy diet is variety. Eating a diverse range of fruits, vegetables, whole grains, and lean proteins can provide our bodies with the nutrients, vitamins, and minerals we need to function at our best. It's important to try to incorporate a rainbow of colours into our diets, as each colour group represents different nutrients and health benefits. For example, orange and yellow fruits and vegetables are rich in vitamin C and beta-carotene, which can support healthy skin and eyesight. Green leafy vegetables like spinach and kale are packed with antioxidants and can help support a healthy immune system. And blue and purple fruits and vegetables, like blueberries and eggplants, are high in flavonoids and can help support brain health and cognitive function.

In addition to eating a variety of fruits and vegetables, it's also important to include whole grains in our diets. Whole grains, like quinoa, brown rice, and oatmeal, are a great source of fibre, which can help keep us feeling full and satisfied. They can also help regulate our blood sugar levels, which can keep our energy levels steady and prevent unhealthy cravings.

“Depending on whom you ask, “healthy eating” may take many forms. It seems that everyone, including healthcare professionals, wellness influencers, coworkers, and family members, has an opinion on the healthiest way to eat. Plus, nutrition articles that you read online can be downright confusing with their contradictory — and often unfounded — suggestions and rules. This doesn’t make it easy if you simply want to eat in a healthy way that works for you.”

Author Jillian Kubala is a registered dietitian and holds a master’s degree in nutrition and an undergraduate degree in nutrition science. In her essay, she says that healthy eating doesn’t have to be complicated and explains how it can nourish your body while enjoying the foods you love. Check out these essays about health .

“Eating provides your body with the nourishment it needs to survive. A healthy diet supplies nutrients (such as protein, vitamins and minerals, fiber, and carbohydrates), which are important for your body’s growth, development, and maintenance. However, not all foods are equal when it comes to the nutrition they provide. Some foods, such as fruits and vegetables, are rich in vitamins and minerals; others, such as cookies and soda pop, provide few if any nutrients. Your diet can influence everything from your energy level and intellectual performance to your risk for certain diseases.”

Author Jaime Padilla talks about the importance of a healthy diet in your body’s growth, development, and maintenance. He also mentioned that having a poor diet can lead to some health problems. Check out these essays about food .

“Eating healthy is about balance and making sure that your body is getting the necessary nutrients it needs to function properly. Healthy eating habits require that people eat fruits, vegetables, whole grains, fats, proteins, and starches. Keep in mind that healthy eating requires that you’re mindful of what you eat and drink, but also how you prepare it. For best results, individuals should avoid fried or processed foods, as well as foods high in added sugars and salts.”

Author Maggie Smith believes there’s a fine line between healthy eating and dieting. In her essay, she mentioned five benefits of eating healthy foods – weight loss, heart health, strong bones and teeth, better mood and energy levels, and improved memory and brain health – and explained them in detail.

“From old generation to the new generation young people are dying out quicker than their own parents due to obesity-related diseases every day. In the mid-1970s, there were no health issues relevant to obesity-related diseases but over time it began to be a problem when fast food industries started growing at a rapid pace. Energy is naturally created in the body when the nutrients are absorbed from the food that is consumed. When living a healthy lifestyle, these horrible health problems don’t appear, and the chances of prolonging life and enjoying life increase.”

In her essay, author Audrey Rodriguez says that having self-control is very important to achieving a healthy lifestyle, especially now that we’re exposed to all these unhealthy yet tempting foods that all these fast-food restaurants offer. She believes that back in the early 1970s, when fast-food companies had not yet existed and home-cooked meals were the only food people had to eat every day, trying to live a healthy life was never a problem.

“A healthful diet typically includes nutrient-dense foods from all major food groups, including lean proteins, whole grains, healthful fats, and fruits and vegetables of many colors. Healthful eating also means replacing foods that contain trans fats, added salt, and sugar with more nutritious options. Following a healthful diet has many health benefits, including building strong bones, protecting the heart, preventing disease, and boosting mood.”

In her essay, Author Cathleen Crichton-Stuart explains the top 10 benefits of eating healthy foods – all of which are medically reviewed by Adrienne Seitz, a registered and licensed dietitian nutritionist. She also gives her readers some quick tips for a healthful diet.

“In today’s generation, healthy and unhealthy food plays a big role in youths and adults. Many people don’t really understand the difference between healthy and unhealthy foods, many don’t actually know what the result of eating too many unhealthy foods can do to the body. There are big differences between eating healthy food, unhealthy food and what the result of excessively eating them can do to the body. In the ongoing battle of “healthy vs. unhealthy foods”, unhealthy foods have their own advantage.”

Author Jaime Padilla compares the difference between healthy food and junk food so that the readers would understand what the result of eating a lot of unhealthy foods can do to the body. He also said that homemade meals are healthier and cheaper than the unhealthy and pricey meals that you order in your local fast food restaurant, which would probably cost you twice as much.

“The Covid-19 pandemic has sparked both an increased clinical and public interest in the role of nutrition and health, particularly in supporting immunity. During this time, when people may be highly vulnerable to misinformation, there have been a plethora of media stories against authoritative scientific opinion, suggesting that certain food components and supplements are capable of ‘boosting’ the immune system. It is important to provide evidence-based advice and to ensure that the use of non-evidence-based approaches to ‘boost’ immunity is not considered as an effective alternative to vaccination or other recognized measures.”

Authors Ayela Spiro, a nutrition science manager, and Helena Gibson-Moore, a nutrition scientist, enlighten their readers on the misinformation spreading in this pandemic about specific food components and supplements. They say that there’s no single food or supplement, or magic diet that can boost the immune system alone. However, eating healthy foods (along with the right dietary supplements), being physically active, and getting enough sleep can help boost your immunity.

If you’re writing an essay about eating healthy foods, you have to define what healthy food is.

Healthy Food Essay

Essay on Healthy Food

Food is essential for our body for a number of reasons. It gives us the energy needed for working, playing and doing day-to-day activities. It helps us to grow, makes our bones and muscles stronger, repairs damaged body cells and boosts our immunity against external harmful elements like pathogens. Besides, food also gives us a kind of satisfaction that is integral to our mental wellbeing, but there are some foods that are not healthy. Only those food items that contain nutrients in a balanced proportion are generally considered as healthy. People of all ages must be aware of the benefits of eating healthy food because it ensures a reasonably disease-free, fit life for many years.

Switching to a healthy diet doesn't have to be a one-size-fits-all approach. You don't have to be perfect, you don't have to eliminate all of your favourite foods and you don't have to make any drastic changes all at once—doing so frequently leads to straying or abandoning your new eating plan.

Making a few tiny modifications at a time is a recommended approach. Maintaining modest goals will help you achieve more in the long run without feeling deprived or overwhelmed by a very drastic diet change. Consider a healthy diet as a series of tiny, accessible actions such as including a salad in your diet once a day. You can slowly add additional healthy options as your minor modifications become habitual.

Cultivating a positive relationship with food is also crucial. Rather than focusing on what you should avoid, consider what you may include on your plate that will benefit your health such as nuts for heart-healthy, predominant fat that reduces low-density lipoprotein levels called monounsaturated fatty acids(raspberries) for fibre and especially the substances that inhibit oxidation which we call antioxidants.

Why is Healthy Food Important?

Living a healthy lifestyle has immense payback. Over time, making smart eating choices lowers your risk of cardiovascular disease, certain malignancies, type 2 diabetes, obesity, and even anxiety and depression. Daily, you will have more energy, feel better and possibly even be in a better mood.

Cereals,potatoes,bread and other root vegetables- These are the main sources of carbohydrates. The calories obtained from them enable us to do work.

Pulses, milk and milk products, eggs, bird meat, animal meat in limited quantities - these are great sources of protein. They build muscles and repair the damaged cells of our body, i.e., they are important for our immunity.

Ghee, butter, nuts and dry fruits, edible oil used in restrained quantities- These are rich sources of good fat. They provide more energy to our body than carbohydrates but should be consumed in a smaller amount.

Fresh fruits, vegetables and leafy vegetables, fish, egg, milk-these are good sources of vitamins, minerals and antioxidants are essential for normal functioning of the body. Though they are needed in small amounts, nowadays, nutrition experts prescribe their higher consumption as they help to fight lifestyle diseases like diabetes, obesity and even cancer.

Different types of healthy food when included in our daily diet in the right proportions along with water and roughage comprise a balanced diet. However, a balanced diet is not the same for all individuals considering many factors. It depends on a person’s age, gender, condition of the body-healthy or suffering from any disease and the type of work or physical activity a human does.

Benefits of Eating Healthy

Healthy food intake nourishes both our physical and mental health and helps us stay active for many years. One who break downs this broad benefit into micro-benefits will see that eating healthy:

Helps in uplifting mood

To fully understand the prominence of healthy food in our diet, we must also be aware of unhealthy food, that is, the food that we must avoid eating. These are mainly junk food items which are low in nutritional value and contain an excessive amount of salt, sugar and fats which is not healthy for a human body.

Junk food is one of the unhealthy intakes in the present day scenario. It makes us more unfit than ever before. It is high time that one realised this and adopted a healthy food habit for a sustainable lifestyle.

Steps to improve Eating Habits:

Make a detailed plan; break down the timings; kind of food to be included in each meal and keep the plan weekly and avoid making the process dull and repetitive.

Cook your food, minimise eating from outside. It helps keep the ingredients, quality and measurements in check as well as saves money.

Stock your kitchen with healthy snacks for your cravings rather than processed food so that your options are reduced to consuming unhealthy food.

Take the process slowly. You do not have to have a strict plan; ease yourself into a healthy mindset. Your mind and body will adjust gradually. Consistency is important.

Myths About Healthy Food:

Carrots affect eyesight: According to historic times, during World War II, there was a popular belief that eating a lot of veggies would assist maintain the pilot's eyes in good repair. In actuality, the fighter pilot's eyesight was aided by advanced technology. However, the myth has persisted since then and many parents still use this narrative to get their children to eat more veggies. Carrots are high in vitamin A and make a terrific supplement to any healthy diet, but they don't usually help you see better.

Fat-Free Food : Health foods continue to dominate grocery store shelves but it's always a good idea to look beyond the label before buying. This is especially true when it comes to "fat-free," "low-fat," and "non-fat" foods. It's generally true that anything with less fat is preferable for some dairy and meat items.

Lower fat alternatives in packaged and processed foods contain other dangerous additives as fat substitutes. Manufacturers compensate for the loss of fat in packaged cookies, for example, by adding other undesirable elements like sugar.

Protein shakes: Pre-made smoothie beverages and protein powder mixes which typically claim to contain less sugar than milkshakes, slushies and diet sodas are likely to be the popular choice among customers because of the above mentioned reason. They both have the same amount of sugar and artificial sweeteners.

However, this is not true of all pre-made protein shakes and smoothies. Many of them, particularly the plant-based mixtures, are still nutritious additions to a balanced diet. Check the nutrition label to be sure there are no added sugars or artificially sweetened mixtures.

Organic food is better: Foods that are grown organically are better for you. Nutritionists labelling a product as organic doesn't mean it's superior to non-organic foods. It's a popular misperception that organic produce is nutritionally superior to non-organic produce. Organic produce has the same caloric and nutritional value as non-organic produce since it is grown and prepared according to federal rules.

FAQs on Healthy Food Essay

Sugar is considered to be harmful for a healthy diet. Since it tastes so good in many foods, humans tend to increase it’s intake. It is also hidden in foods you wouldn't expect.

Introduction

In this argumentative research essay for a first-year composition class, student Lily Tran creates a solid, focused argument and supports it with researched evidence. Throughout the essay, she uses this evidence to support cause-and-effect and problem-solution reasoning, make strong appeals, and develop her ethos on the topic.

Living by Their Own Words

Food as change.

public domain text For the human race to have a sustainable future, massive changes in the way food is produced, processed, and distributed are necessary on a global scale. end public domain text

annotated text Purpose. Lily Tran refers to what she sees as the general purpose for writing this paper: the problem of current global practices in food production, processing, and distribution. By presenting the “problem,” she immediately prepares readers for her proposed solution. end annotated text

public domain text The required changes will affect nearly all aspects of life, including not only world hunger but also health and welfare, land use and habitats, water quality and availability, energy use and production, greenhouse gas emissions and climate change, economics, and even cultural and social values. These changes may not be popular, but they are imperative. The human race must turn to sustainable food systems that provide healthy diets with minimal environmental impact—and starting now. end public domain text

annotated text Thesis. Leading up to this clear, declarative thesis statement are key points on which Tran will expand later. In doing this, she presents some foundational evidence that connects the problem to the proposed solution. end annotated text

THE COMING FOOD CRISIS

public domain text The world population has been rising exponentially in modern history. From 1 billion in 1804, it doubled to approximately 2 billion by 1927, then doubled again to approximately 4 billion in 1974. By 2019, it had nearly doubled again, rising to 7.7 billion (“World Population by Year”). It has been projected to reach nearly 10 billion by 2050 (Berners-Lee et al.). At the same time, the average life span also has been increasing. These situations have led to severe stress on the environment, particularly in the demands for food. It has been estimated, for example, that by 2050, milk production will increase 58 percent and meat production 73 percent (Chai et al.). end public domain text

annotated text Evidence. In this first supporting paragraph, Tran uses numerical evidence from several sources. This numerical data as evidence helps establish the projection of population growth. By beginning with such evidence, Tran underscores the severity of the situation. end annotated text

public domain text Theoretically, the planet can produce enough food for everyone, but human activities have endangered this capability through unsustainable practices. Currently, agriculture produces 10–23 percent of global greenhouse gas emissions. Greenhouse gases—the most common being carbon dioxide, methane, nitrous oxide, and water vapor— trap heat in the atmosphere, reradiate it, and send it back to Earth again. Heat trapped in the atmosphere is a problem because it causes unnatural global warming as well as air pollution, extreme weather conditions, and respiratory diseases. end public domain text

annotated text Audience. With her audience in mind, Tran briefly explains the problem of greenhouse gases and global warming. end annotated text

public domain text It has been estimated that global greenhouse gas emissions will increase by as much as 150 percent by 2030 (Chai et al.). Transportation also has a negative effect on the environment when foods are shipped around the world. As Joseph Poore of the University of Oxford commented, “It’s essential to be mindful about everything we consume: air-transported fruit and veg can create more greenhouse gas emissions per kilogram than poultry meat, for example” (qtd. in Gray). end public domain text

annotated text Transition. By beginning this paragraph with her own transition of ideas, Tran establishes control over the organization and development of ideas. Thus, she retains her sources as supports and does not allow them to dominate her essay. end annotated text

public domain text Current practices have affected the nutritional value of foods. Concentrated animal-feeding operations, intended to increase production, have had the side effect of decreasing nutritional content in animal protein and increasing saturated fat. One study found that an intensively raised chicken in 2017 contained only one-sixth of the amount of omega-3 fatty acid, an essential nutrient, that was in a chicken in 1970. Today the majority of calories in chicken come from fat rather than protein (World Wildlife Fund). end public domain text

annotated text Example. By focusing on an example (chicken), Tran uses specific research data to develop the nuance of the argument. end annotated text

public domain text Current policies such as government subsidies that divert food to biofuels are counterproductive to the goal of achieving adequate global nutrition. Some trade policies allow “dumping” of below-cost, subsidized foods on developing countries that should instead be enabled to protect their farmers and meet their own nutritional needs (Sierra Club). Too often, agriculture’s objectives are geared toward maximizing quantities produced per acre rather than optimizing output of critical nutritional needs and protection of the environment. end public domain text

AREAS OF CONCERN

Hunger and nutrition.

annotated text Headings and Subheadings. Throughout the essay, Tran has created headings and subheadings to help organize her argument and clarify it for readers. end annotated text

public domain text More than 820 million people around the world do not have enough to eat. At the same time, about a third of all grains and almost two-thirds of all soybeans, maize, and barley crops are fed to animals (Barnard). According to the World Health Organization, 462 million adults are underweight, 47 million children under 5 years of age are underweight for their height, 14.3 million are severely underweight for their height, and 144 million are stunted (“Malnutrition”). About 45 percent of mortality among children under 5 is linked to undernutrition. These deaths occur mainly in low- and middle-income countries where, in stark contrast, the rate of childhood obesity is rising. Globally, 1.9 billion adults and 38.3 million children are overweight or obese (“Obesity”). Undernutrition and obesity can be found in the same household, largely a result of eating energy-dense foods that are high in fat and sugars. The global impact of malnutrition, which includes both undernutrition and obesity, has lasting developmental, economic, social, and medical consequences. end public domain text

public domain text In 2019, Berners-Lee et al. published the results of their quantitative analysis of global and regional food supply. They determined that significant changes are needed on four fronts: end public domain text

Food production must be sufficient, in quantity and quality, to feed the global population without unacceptable environmental impacts. Food distribution must be sufficiently efficient so that a diverse range of foods containing adequate nutrition is available to all, again without unacceptable environmental impacts. Socio-economic conditions must be sufficiently equitable so that all consumers can access the quantity and range of foods needed for a healthy diet. Consumers need to be able to make informed and rational choices so that they consume a healthy and environmentally sustainable diet (10).

annotated text Block Quote. The writer has chosen to present important evidence as a direct quotation, using the correct format for direct quotations longer than four lines. See Section Editing Focus: Integrating Sources and Quotations for more information about block quotes. end annotated text

public domain text Among their findings, they singled out, in particular, the practice of using human-edible crops to produce meat, dairy, and fish for the human table. Currently 34 percent of human-edible crops are fed to animals, a practice that reduces calorie and protein supplies. They state in their report, “If society continues on a ‘business-as-usual’ dietary trajectory, a 119% increase in edible crops grown will be required by 2050” (1). Future food production and distribution must be transformed into systems that are nutritionally adequate, environmentally sound, and economically affordable. end public domain text

Land and Water Use

public domain text Agriculture occupies 40 percent of Earth’s ice-free land mass (Barnard). While the net area used for producing food has been fairly constant since the mid-20th century, the locations have shifted significantly. Temperate regions of North America, Europe, and Russia have lost agricultural land to other uses, while in the tropics, agricultural land has expanded, mainly as a result of clearing forests and burning biomass (Willett et al.). Seventy percent of the rainforest that has been cut down is being used to graze livestock (Münter). Agricultural use of water is of critical concern both quantitatively and qualitatively. Agriculture accounts for about 70 percent of freshwater use, making it “the world’s largest water-consuming sector” (Barnard). Meat, dairy, and egg production causes water pollution, as liquid wastes flow into rivers and to the ocean (World Wildlife Fund and Knorr Foods). According to the Hertwich et al., “the impacts related to these activities are unlikely to be reduced, but rather enhanced, in a business-as-usual scenario for the future” (13). end public domain text

annotated text Statistical Data. To develop her points related to land and water use, Tran presents specific statistical data throughout this section. Notice that she has chosen only the needed words of these key points to ensure that she controls the development of the supporting point and does not overuse borrowed source material. end annotated text

annotated text Defining Terms. Aware of her audience, Tran defines monocropping , a term that may be unfamiliar. end annotated text

public domain text Earth’s resources and ability to absorb pollution are limited, and many current agricultural practices undermine these capacities. Among these unsustainable practices are monocropping [growing a single crop year after year on the same land], concentrated animal-feeding operations, and overdependence on manufactured pesticides and fertilizers (Hamilton). Such practices deplete the soil, dramatically increase energy use, reduce pollinator populations, and lead to the collapse of resource supplies. One study found that producing one gram of beef for human consumption requires 42 times more land, 2 times more water, and 4 times more nitrogen than staple crops. It also creates 3 times more greenhouse gas emissions (Chai et al.). The EAT– Lancet Commission calls for “halting expansion of new agricultural land at the expense of natural ecosystems . . . strict protections on intact ecosystems, suspending concessions for logging in protected areas, or conversion of remaining intact ecosystems, particularly peatlands and forest areas” (Willett et al. 481). The Commission also calls for land-use zoning, regulations prohibiting land clearing, and incentives for protecting natural areas, including forests. end public domain text

annotated text Synthesis. The paragraphs above and below this comment show how Tran has synthesized content from several sources to help establish and reinforce key supports of her essay . end annotated text

Greenhouse Gas and Climate Change

public domain text Climate change is heavily affected by two factors: greenhouse gas emissions and carbon sequestration. In nature, the two remain in balance; for example, most animals exhale carbon dioxide, and most plants capture carbon dioxide. Carbon is also captured, or sequestered, by soil and water, especially oceans, in what are called “sinks.” Human activities have skewed this balance over the past two centuries. The shift in land use, which exploits land, water, and fossil energy, has caused increased greenhouse-gas emissions, which in turn accelerate climate change. end public domain text

public domain text Global food systems are threatened by climate change because farmers depend on relatively stable climate systems to plan for production and harvest. Yet food production is responsible for up to 30 percent of greenhouse gas emissions (Barnard). While soil can be a highly effective means of carbon sequestration, agricultural soils have lost much of their effectiveness from overgrazing, erosion, overuse of chemical fertilizer, and excess tilling. Hamilton reports that the world’s cultivated and grazed soils have lost 50 to 70 percent of their ability to accumulate and store carbon. As a result, “billions of tons of carbon have been released into the atmosphere.” end public domain text

annotated text Direct Quotation and Paraphrase. While Tran has paraphrased some content of this source borrowing, because of the specificity and impact of the number— “billions of tons of carbon”—she has chosen to use the author’s original words. As she has done elsewhere in the essay, she has indicated these as directly borrowed words by placing them within quotation marks. See Section 12.5 for more about paraphrasing. end annotated text

public domain text While carbon sequestration has been falling, greenhouse gas emissions have been increasing as a result of the production, transport, processing, storage, waste disposal, and other life stages of food production. Agriculture alone is responsible for fully 10 to 12 percent of global emissions, and that figure is estimated to rise by up to 150 percent of current levels by 2030 (Chai et al.). Münter reports that “more greenhouse gas emissions are produced by growing livestock for meat than all the planes, trains, ships, cars, trucks, and all forms of fossil fuel-based transportation combined” (5). Additional greenhouse gases, methane and nitrous oxide, are produced by the decomposition of organic wastes. Methane has 25 times and nitrous oxide has nearly 300 times the global warming potential of carbon dioxide (Curnow). Agricultural and food production systems must be reformed to shift agriculture from greenhouse gas source to sink. end public domain text

Social and Cultural Values

public domain text As the Sierra Club has pointed out, agriculture is inherently cultural: all systems of food production have “the capacity to generate . . . economic benefits and ecological capital” as well as “a sense of meaning and connection to natural resources.” Yet this connection is more evident in some cultures and less so in others. Wealthy countries built on a consumer culture emphasize excess consumption. One result of this attitude is that in 2014, Americans discarded the equivalent of $165 billion worth of food. Much of this waste ended up rotting in landfills, comprised the single largest component of U.S. municipal solid waste, and contributed a substantial portion of U.S. methane emissions (Sierra Club). In low- and middle-income countries, food waste tends to occur in early production stages because of poor scheduling of harvests, improper handling of produce, or lack of market access (Willett et al.). The recent “America First” philosophy has encouraged prioritizing the economic welfare of one nation to the detriment of global welfare and sustainability. end public domain text

annotated text Synthesis and Response to Claims. Here, as in subsequent sections, while still relying heavily on facts and content from borrowed sources, Tran provides her synthesized understanding of the information by responding to key points. end annotated text

public domain text In response to claims that a vegetarian diet is a necessary component of sustainable food production and consumption, Lusk and Norwood determined the importance of meat in a consumer’s diet. Their study indicated that meat is the most valuable food category to consumers, and “humans derive great pleasure from consuming beef, pork, and poultry” (120). Currently only 4 percent of Americans are vegetarians, and it would be difficult to convince consumers to change their eating habits. Purdy adds “there’s the issue of philosophy. A lot of vegans aren’t in the business of avoiding animal products for the sake of land sustainability. Many would prefer to just leave animal husbandry out of food altogether.” end public domain text

public domain text At the same time, consumers expect ready availability of the foods they desire, regardless of health implications or sustainability of sources. Unhealthy and unsustainable foods are heavily marketed. Out-of-season produce is imported year-round, increasing carbon emissions from air transportation. Highly processed and packaged convenience foods are nutritionally inferior and waste both energy and packaging materials. Serving sizes are larger than necessary, contributing to overconsumption and obesity. Snack food vending machines are ubiquitous in schools and public buildings. What is needed is a widespread attitude shift toward reducing waste, choosing local fruits and vegetables that are in season, and paying attention to how foods are grown and transported. end public domain text

annotated text Thesis Restated. Restating her thesis, Tran ends this section by advocating for a change in attitude to bring about sustainability. end annotated text

DISSENTING OPINIONS

annotated text Counterclaims . Tran uses equally strong research to present the counterargument. Presenting both sides by addressing objections is important in constructing a clear, well-reasoned argument. Writers should use as much rigor in finding research-based evidence to counter the opposition as they do to develop their argument. end annotated text

public domain text Transformation of the food production system faces resistance for a number of reasons, most of which dispute the need for plant-based diets. Historically, meat has been considered integral to athletes’ diets and thus has caused many consumers to believe meat is necessary for a healthy diet. Lynch et al. examined the impact of plant-based diets on human physical health, environmental sustainability, and exercise performance capacity. The results show “it is unlikely that plant-based diets provide advantages, but do not suffer from disadvantages, compared to omnivorous diets for strength, anaerobic, or aerobic exercise performance” (1). end public domain text

public domain text A second objection addresses the claim that land use for animal-based food production contributes to pollution and greenhouse gas emissions and is inefficient in terms of nutrient delivery. Berners-Lee et al. point out that animal nutrition from grass, pasture, and silage comes partially from land that cannot be used for other purposes, such as producing food directly edible by humans or for other ecosystem services such as biofuel production. Consequently, nutritional losses from such land use do not fully translate into losses of human-available nutrients (3). end public domain text

annotated text Paraphrase. Tran has paraphrased the information as support. Though she still cites the source, she has changed the words to her own, most likely to condense a larger amount of original text or to make it more accessible. end annotated text

public domain text While this objection may be correct, it does not address the fact that natural carbon sinks are being destroyed to increase agricultural land and, therefore, increase greenhouse gas emissions into the atmosphere. end public domain text

public domain text Another significant dissenting opinion is that transforming food production will place hardships on farmers and others employed in the food industry. Farmers and ranchers make a major investment in their own operations. At the same time, they support jobs in related industries, as consumers of farm machinery, customers at local businesses, and suppliers for other industries such as food processing (Schulz). Sparks reports that “livestock farmers are being unfairly ‘demonized’ by vegans and environmental advocates” and argues that while farming includes both costs and benefits, the costs receive much more attention than the benefits. end public domain text

FUTURE GENERATIONS

public domain text The EAT– Lancet Commission calls for a transformation in the global food system, implementing different core processes and feedback. This transformation will not happen unless there is “widespread, multi-sector, multilevel action to change what food is eaten, how it is produced, and its effects on the environment and health, while providing healthy diets for the global population” (Willett et al. 476). System changes will require global efforts coordinated across all levels and will require governments, the private sector, and civil society to share a common vision and goals. Scientific modeling indicates 10 billion people could indeed be fed a healthy and sustainable diet. end public domain text

annotated text Conclusion. While still using research-based sources as evidence in the concluding section, Tran finishes with her own words, restating her thesis. end annotated text

public domain text For the human race to have a sustainable future, massive changes in the way food is produced, processed, and distributed are necessary on a global scale. The required changes will affect nearly all aspects of life, including not only world hunger but also health and welfare, land use and habitats, water quality and availability, energy use and production, greenhouse gas emissions and climate change, economics, and even cultural and social values. These changes may not be popular, but they are imperative. They are also achievable. The human race must turn to sustainable food systems that provide healthy diets with minimal environmental impact, starting now. end public domain text

annotated text Sources. Note two important aspects of the sources chosen: 1) They represent a range of perspectives, and 2) They are all quite current. When exploring a contemporary topic, it is important to avoid research that is out of date. end annotated text

Healthy Food Essay (100, 150 and 500 words Essay)

Healthy food is essential for humans to nourish their bodies with proper nutrients. Educating students about healthy eating is vital and essays are a great way to learn about it. Here are 100, 150, 200, and 500-word essays that educate students about the importance of healthy eating habits.

100-word Healthy Food Essay

Healthy food is necessary to sustain life. The terms health and food go hand in hand because healthy food can contribute to both mental well-being and physical well-being. From childhood, we have been told to maintain a properly balanced diet that includes all components of food in adequate proportion.

This makes sure we get all vitamins, minerals, protein, and other nutrients from our daily meals. These nutrients nourish our bodies and keep our organs from malfunctioning. Junk foods satisfy our taste buds but are quite harmful in the long run as they fill our stomachs for a short period-and have little to no nutritional value.

150-word Healthy food essay

The proverb “Health is wealth” is indeed true because, without good health, our body won’t able to perform the simplest tasks. By choosing healthy foods, we can live a longer and more fulfilling lives. We learn about a properly balanced diet in schools that conveys the idea of getting adequate nutrition each day through our food for proper bodily function, which is quite important.

A balanced diet provides us with nutrients like protein, carbohydrates, vitamins, minerals, antioxidants, and more. These nutrients are necessary to sustain life and keep our organs healthy. If we consume junk foods constantly that are high in calories, sugar, salt, our organs are at a risk of malfunctioning. These foods contain the least amount of nutrition and are not good for one’s physical health. This is why eating healthy is important because healthy foods promote our physical well-being. Junk foods have become quite popular since they require lesser time to cook and are very delicious. But we cannot avoid how they harm our health. Junk foods have high amounts of fats and carbohydrates that can lead to weight gain and other chronic diseases like diabetes, high blood pressure, heart problems, and many more.

On the other hand, eating healthy foods has a plethora of benefits. These foods contribute to not only a sound body, but also a sound mind. Nutrients like antioxidants, vitamins, minerals, and protein nourish our bodies and also benefit our different organs. Fruits contain a variety of vitamins and antioxidants, plus they taste amazing. Green leafy vegetables are loaded with nutrients, while beans and lentils contain good amounts of protein.Dry fruits like almonds and walnuts are a great snacking option and are rich in the nutrient Omega-3. Also drinking water regularly helps in flushing out toxins from our body.

Hence for the overall human well-being, healthy foods play a crucial role. They can control weight gain, and make us more active and alert. They also protect us against various non-chronic and chronic diseases and adds more years to our lives by making us fit and healthy.

500-word Healthy Food Essay

Healthy food is a crucial building block for our health and overall well-being. Food is necessary to sustain life, just after water. And maintaining a healthy diet that provides us with proper nutrition is even more important.Eating is dependent on nutrition. We carry out our day-to-day activities because of the nutrition our food provides us.

It is necessary to be mindful of what we put into our bodies because food can easily make your break your overall health. In today’s busy lifestyle, junk foods have taken the upper hand because of their convenience and cheap prices. They are easy to grab on the go and are heaven for the taste buds. However, consuming them regularly can seriously harm our insides. Junk foods are notorious for containing almost no nutritional value, mostly just comprising a high amount of carbohydrates and calories. Even small portions of burgers, pizzas, and fries contain a big amount of calories. Drinks like cola contain high amounts of sugar which easily surpasses our daily instructed intake of sugar. Processed and packaged foods contain preservatives that can harm our precious health. People suffering from mental health issues also develop a habit of binge eating junk foods as a coping mechanism that goes on to severely harm their physical and mental health.

Indulging in these types of foods in limited amounts every once in a while is harmless, however, they should not become a part of our daily diet. We need to understand what kinds of foods provide us with the nutrition we need daily and inculcate them into our diet. Portion control is also very important when trying to maintain or lose weight. Also, one should avoid going on crash diets that are not sustainable in the longer run. A properly balanced meal for breakfast, lunch, and dinner is important to look and feel good inside out. Eating healthy also gives us a sense of achievement that we are taking care of our bodies. Eating nutrition-dense meals and drinking eight glasses of water a day can have a very positive effect not only on our body but also on our mental health.

In our life, if our health is not in good condition, we would slowly lose everything else. Therefore listening to our body and taking good care of it is vital. At first, most people can be unsure where to start. But there are dozens of recipes and health books online that could guide you towards a better lifestyle. Start with foods that contain high amounts of protein, fiber, vitamins, and minerals like meat, beans, lentils, poultry, and fermented foods. These nourish your body with necessary nutrients and keep you full for a longer amount of time. This is also beneficial to avoid mindless snacking.

Diet and exercise go hand in hand when one speaks of maintaining good health. This is why creating a proper workout routine along with eating healthy can have a significant effect on our overall health.

Nutrition generally refers to the macro- and micro-nutrients essential for survival, but we do not simply eat nutrition. Instead, we eat animal- and plant-based foods without always being conscious of its nutritional value. Furthermore, various cultural factors influence and shape our taste, preferences, taboos and practices towards preparing and consuming food as a meal and diet. Biogerontological understanding of ageing has identified food as one of the three foundational pillars of health and survival. Here we address the issues of nutrition, food and diet by analyzing the biological importance of macro- and micro-nutrients including hormetins, discussing the health claims for various types of food, and by reviewing the general principles of healthy dietary patterns, including meal timing, caloric restriction, and intermittent fasting. We also present our views about the need for refining our approaches and strategies for future research on nutrition, food and diet by incorporating the molecular, physiological, cultural and personal aspects of this crucial pillar of health, healthy ageing and longevity.

1. Introduction

The terms nutrition, food and diet are often used interchangeably. However, whereas nutrition generally refers to the macro- and micro-nutrients essential for survival, we do not simply eat nutrition, which could, in principle, be done in the form of a pill. Instead, we eat food which normally originates from animal- and plant-based sources, without us being aware of or conscious of its nutritional value. Even more importantly, various cultural factors influence and shape our taste, preferences, taboos and practices towards preparing and consuming food as a meal and diet [ 1 ]. Furthermore, geo-political-economic factors, such as governmental policies that oversee the production and consumption of genetically modified foods, geological/climatic challenges of growing such crops in different countries, and the economic affordability of different populations for such foods, also influence dietary habits and practices [ 2 , 3 ]. On top of all this lurks the social evolutionary history of our species, previously moving towards agriculture-based societies from the hunter-gatherer lifestyle, now becoming the consumers of industrially processed food products that affect our general state of health, the emergence of diseases, and overall lifespan [ 1 , 4 ]. The aim of this article is to provide a commentary and perspective on nutrition, food and diet in the context of health, healthy ageing and longevity.

Biogerontological understanding of ageing has identified food as one of the three foundational pillars of health and survival. The other two pillars, especially in the case of human beings, are physical exercise and socio-mental engagement [ 5 , 6 , 7 ]. A huge body of scientific and evidence-based information has been amassed with respect to the qualitative and quantitative nature of optimal nutrition for human health and survival. Furthermore, a lot more knowledge has developed regarding how different types of foods provide different kinds of nutrition to different extents, and how different dietary practices have either health-beneficial or health-harming effects.

Here we endeavor to address these issues of nutrition, food and diet by analyzing the biological importance of macro- and micro-nutrients, and by discussing the health-claims about animal-based versus plant-based foods, fermented foods, anti-inflammatory foods, functional foods, foods for brain health, and so on. Finally, we discuss the general principles of healthy dietary patterns, including the importance of circadian rhythms, meal timing, chronic caloric restriction (CR), and intermittent fasting for healthy ageing and extended lifespan [ 8 , 9 ]. We also present our views about the need for refining our approaches and strategies for future research on nutrition, food and diet by incorporating the molecular, physiological, cultural and personal aspects of this crucial pillar of health, healthy ageing and longevity.

2. Nutrition for Healthy Ageing

The science of nutrition or the “nutritional science” is a highly advanced field of study, and numerous excellent books, journals and other resources are available for fundamental information about all nutritional components [ 10 ]. Briefly, the three essential macronutrients which provide the basic materials for building biological structures and for producing energy required for all physiological and biochemical processes are proteins, carbohydrates and lipids. Additionally, about 18 micronutrients, comprised of minerals and vitamins, facilitate the optimal utilization of macronutrients via their role in the catalysis of numerous biochemical processes, in the enhancement of their bioavailability and absorption, and in the balancing of the microbiome. Scientific literature is full of information about almost all nutritional components with respect to their importance and role in basic metabolism for survival and health throughout one’s life [ 10 ].

In the context of ageing, a major challenge to maintain health in old age is the imbalanced nutritional intake resulting into nutritional deficiency or malnutrition [ 11 , 12 ]. Among the various reasons for such a condition is the age-related decline in the digestive and metabolic activities, exacerbated by a reduced sense of taste and smell and worsening oral health, including the ability to chew and swallow [ 13 , 14 ]. Furthermore, an increased dependency of the older persons on medications for the management or treatment of various chronic conditions can be antagonistic to certain essential nutrients. For example, long term use of metformin, which is the most frequently prescribed drug against Type 2 diabetes, reduces the levels of vitamin B12 and folate in the body [ 15 , 16 ]. Some other well-known examples of the drugs used for the management or treatment of age-related conditions are cholesterol-lowering medicine statin which can cause coenzyme Q10 levels to be too low; various diuretics (water pills) can cause potassium levels to be too low; and antacids can decrease the levels of vitamin B12, calcium, magnesium and other minerals [ 15 , 16 ]. Thus, medications used in the treatment of chronic diseases in old age can also be “nutrient wasting” or “anti-nutrient” and may cause a decrease in the absorption, bioavailability and utilization of essential micronutrients and may have deleterious effects to health [ 11 ]. In contrast, many nutritional components have the potential to interact with various drugs leading to reduced therapeutic efficacy of the drug or increased adverse effects of the drug, which can have serious health consequences. For example, calcium in dairy products like milk, cheese and yoghurt can inhibit the absorption of antibiotics in the tetracycline and quinolone class, thus compromising their ability to treat infection effectively. Some other well-known examples of food sources which can alter the pharmacokinetics and pharmacodynamics of various drugs are grape fruits, bananas, apple juice, orange juice, soybean flour, walnuts and high-fiber foods (see: https://www.aarp.org/health/drugs-supplements/info-2022/food-medication-interaction.html (accessed on 13 November 2022)).

It is also known that the nutritional requirements of older persons differ both qualitatively and quantitatively from young adults [ 11 ]. This is mainly attributed to the age-related decline in the bioavailability of nutrients, reduced appetite, also known as ‘anorexia of ageing,’ as well as energy expenditure [ 12 , 17 , 18 ]. Therefore, in order to maintain a healthy energy balance, the daily uptake of total calories may need to be curtailed without adversely affecting the nutritional balance. This may be achieved by using nutritional supplements with various vitamins, minerals and other micronutrients, without adding to the burden of total calories [ 12 , 17 , 18 ]. More recently, the science of nutrigenomics (how various nutrients affect gene expression), and the science of nutrigenetics (how individual genetic variations respond to different nutrients) are generating novel and important information on the role of nutrients in health, survival and longevity.

3. Food for Healthy Ageing

The concept of healthy ageing is still being debated among biogerontologists, social-gerontologists and medical practioners. It is generally agreed that an adequate physical and mental independence in the activities of daily living can be a pragmatic definition of health in old age [ 7 ]. Thus, healthy ageing can be understood as a state of maintaining, recovering and enhancing health in old age, and the foods and dietary practices which facilitate achieving this state can be termed as healthy foods and diets.

From this perspective, although nutritional requirements for a healthy and long life could be, in principle, fulfilled by simply taking macro- and micro-nutrients in their pure chemical forms, that is not realistic, practical, attractive or acceptable to most people. In practice, nutrition is obtained by consuming animals and plants as sources of proteins, carbohydrates, fats and micronutrients. There is a plethora of tested and reliable information available about various food sources with respect to the types and proportion of various nutrients present in them. However, there are still ongoing discussions and debates as to what food sources are best for human health and longevity [ 19 , 20 ]. Often such discussions are emotionally highly charged with arguments based on faith, traditions, economy and, more recently, on political views with respect to the present global climate crisis and sustainability.

Scientifically, there is no ideal food for health and longevity. Varying agricultural and food production practices affect the nutritional composition, durability and health beneficial values of various foods. Furthermore, the highly complex “science of cooking” [ 21 ], evolved globally during thousands of years of human cultural evolution, has discovered the pros and cons of food preparation methods such as soaking, boiling, frying, roasting, fermenting and other modes of extracting, all with respect to how best to use these food sources for increasing the digestibility and bioavailability of various nutrients, as well as how to eliminate the dangers and toxic effects of other chemicals present in the food.

The science of food preparation and utilization has also discovered some paradoxical uses of natural compounds, especially the phytochemicals such as polyphenols, flavonoids, terpenoids and others. Most of these compounds are produced by plants as toxins in response to various stresses, and as defenses against microbial infections [ 22 , 23 ]. However, humans have discovered, mostly by trial and error, that numerous such toxic compounds present in algae, fungi, herbs and other sources can be used in small doses as spices and condiments with potential benefits of food preservation, taste enhancement and health promotion [ 23 ].

The phenomenon of “physiological hormesis” [ 24 ] is a special example of the health beneficial effects of phytotoxins. According to the concept of hormesis, a deliberate and repeated use of low doses of natural or synthetic toxins in the food can induce one or more stress responses in cells and tissues, followed by the stimulation of numerous defensive repair and maintenance processes [ 25 , 26 ]. Such hormesis-inducing compounds and other conditions are known as hormetins, categorized as nutritional, physical, biological and mental hormetins [ 27 , 28 , 29 ]. Of these, nutritional hormetins, present naturally in the food or as synthetic hormetins to be used as food supplements, are attracting great attention from food-researchers and the nutraceutical and cosmeceutical industry [ 27 , 30 ]. Other food supplements being tested and promoted for health and longevity are various prebiotics and probiotics strengthening and balancing our gut microbiota [ 31 , 32 , 33 ].

Recently, food corporations in pursuit of both exploiting and creating a market for healthy ageing products, have taken many initiatives in producing new products under the flagship of nutraceuticals, super-foods, functional foods, etc. Such products are claimed and marketed not only for their nutritional value, but also for their therapeutic potentials [ 10 ]. Often the claims for such foods are hyped and endorsed as, for example, anti-inflammatory foods, food for the brain, food for physical endurance, complete foods, anti-ageing foods and so on [ 34 , 35 , 36 ]. Traditional foods enriched with a variety of minerals, vitamins and hormetins are generally promoted as “functional foods” [ 37 ]. Even in the case of milk and dairy products, novel and innovative formulations are claimed to improve their functionality and health promotional abilities [ 38 ]. However, there is yet a lot to be discovered and understood about such reformulated, fortified and redesigned foods with respect to their short- and long-term effects on physiology, microbiota balance and metabolic disorders in the context of health and longevity.

4. Diet and Culture for Healthy and Long Life

What elevates food to become diet and a meal is the manner and the context in which that food is consumed [ 4 ]. Numerous traditional and socio-cultural facets of dietary habits can be even more significant than their molecular, biochemical, and physiological concerns regarding their nutritional ingredients and composition. For example, various well-known diets, such as the paleo, the ketogenic, the Chinese, the Ayurvedic, the Mediterranean, the kosher, the halal, the vegetarian, and more recently, the vegan diet, are some of the diverse expressions of such cultural, social, and political practices [ 1 ]. The consequent health-related claims of such varied dietary patterns have influenced their acceptance and adaptation globally and cross-culturally.

Furthermore, our rapidly developing understanding about how biological daily rhythms affect and regulate nutritional needs, termed “chrono-nutrition”, has become a crucial aspect of optimal and healthy eating habits [ 39 , 40 ]. A similar situation is the so-called “nutrient timing” that involves consuming food at strategic times for achieving certain specific outcomes, such as weight reduction, muscle strength, and athletic performance. The meal-timing and dietary patterns are more anticipatory of health-related outcomes than any specific foods or nutrients by themselves [ 41 , 42 , 43 , 44 ]. However, encouraging people to adopt healthy dietary patterns and meal-timing requires both the availability, accessibility and affordability of food, and the intentional, cultural and behavioral preferences of the people.

Looking back at the widely varying and constantly changing cultural history of human dietary practices, one realizes that elaborate social practices, rituals and normative behaviors for obtaining, preparing and consuming food, are often more critical aspects of health-preservation and health-promotion than just the right combination of nutrients. Therefore, one cannot decide on a universal food composition and consumption pattern ignoring the history and the cultural practices and preferences of the consumers. After all, “we eat what we are”, and not, as the old adage says, “we are what we eat”.

5. Conclusions and Perspectives

Food is certainly one of the foundational pillars of good and sustained health. Directed and selective evolution through agricultural practices and experimental manipulation and modification of food components have been among the primary targets for improving food quality. This is further authenticated by extensive research performed, mainly on experimental animal and cell culture model systems, demonstrating the health-promoting effects of individual nutritional components and biological extracts in the regulation, inhibition or stimulation of different molecular pathways with reference to healthy ageing and longevity [ 45 ]. Similarly, individual nutrients or a combination of a few nutrients are being tested for their potential use as calorie restriction mimetics, hormetins and senolytics [ 46 , 47 , 48 ]. However, most commonly, these therapeutic strategies follow the traditional “one target, one missile” pharmaceutical-like approach, and consider ageing as a treatable disease. Based on the results obtained from such experimental studies, the claims and promises made which can often be either naïve extrapolations from experimental model systems to human applications, or exaggerated claims and even false promises [ 49 ].

Other innovative, and possibly holistic, food- and diet-based interventional strategies for healthy ageing are adopting regimens such as caloric- and dietary-restriction, as well as time-restricted eating (TRE). Intermittent fasting (IF), the regimen based on manipulating the eating/fasting timing, is another promising interventional strategy for healthy ageing. Chrono-nutrition, which denotes the link between circadian rhythms and nutrient-sensing pathways, is a novel concept illustrating how meal timings alignment with the inherent molecular clocks of the cells functions to preserve metabolic health. TRE, which is a variant of the IF regimen, claims that food intake timing in alignment with the circadian rhythm is more beneficial for health and longevity [ 39 , 40 , 41 , 50 ]. Moreover, TRE has translational benefits and is easy to complete in the long term as it only requires limiting the eating time to 8–10 h during the day and the fasting window of 12–16 h without restricting the amount of calories consumed. Some pilot studies on the TRE regimen have reported improvement in glucose tolerance and the management of body weight and blood pressure in obese adults as well as men at risk of T2D. Meta-analyses of several pilot scale studies in human subjects suggest and support the beneficial effects of a TRE regimen on several health indicators [ 39 , 50 ]. Several other practical recommendations, based on human clinical trials have also been recommended for meeting the optimal requirements of nutrition in old age, and for preventing or slowing down the progression of metabolic syndromes [ 39 , 40 , 41 , 50 ].

What we have earlier discussed in detail [ 4 ] is supported by the following quote: “…food is more than just being one of the three pillars of health. Food is both the foundation and the scaffolding for the building and survival of an organism on a daily basis. Scientific research on the macro- and micro-nutrient components of food has developed deep understanding of their molecular, biochemical and physiological roles and modes of action. Various recommendations are repeatedly made and modified for some optimal daily requirements of nutrients for maintaining and enhancing health, and for the prevention and treatment of diseases. Can we envisage developing a “nutrition pill” for perfect health, which could be used globally, across cultures, and at all ages? We don’t think so” [ 4 ].

Our present knowledge about the need and significance of nutrients is mostly gathered from the experimental studies using individual active components isolated from various food sources. In reality, however, these nutritional components co-exist interactively with numerous other compounds, and often become chemically modified through the process of cooking and preservation, affecting their stability and bioavailability. There is still a lot to be understood about how the combination of foods, cooking methods and dietary practices affect health-related outcomes, especially with respect to ageing and healthspan.

An abundance of folk knowledge in all cultures about food-related ‘dos and don’ts’ requires scientific verification and validation. We also need to reconsider and change our present scientific protocols for nutritional research, which seem to be impractical for food and dietary research at the level of the population. It is a great scientific achievement that we have amassed a body of information with respect to the nature of nutritional components required for health and survival, the foods which can provide those nutritional components and the variety of dietary and eating practices which seem to be optimal for healthy survival and longevity.

Finally, whereas abundant availability of and accessibility to food in some parts of the world has led to over-consumption and consequent life-style-induced metabolic diseases and obesity, in many other parts of the world food scarcity and economic disparity continue to perpetuate starvation, malnutrition, poor health and shortened lifespan. Often, it is not a lack of knowledge about the optimal nutrition, food and diet that leads to making bad choices; rather, it is either our inability to access and afford healthy foods or our gullibility to fall prey to the exaggerated claims in the commercial interests of food producing and marketing companies. We must continue to gather more scientific information and knowledge about the biochemical, physiological and cultural aspects of nutrition, food and diet, which should then be recommended and applied wisely and globally, incorporating the social, cultural and environmental needs of all. After all, “we eat what we are”, and not merely “we are what we eat”!

Healthy Nutrition: Affordable Food Essay

“ What’s on your plate?” is a provocative and witty documentary produced as well as directed concerning children and food politics. The movie is about two teenagers who are exploring where they are positioned in the food chain. Safiyah, as well as Sadie, take a deeper look at New York City’s food systems plus its environment. They speak to one another as they film themselves addressing farmers, food activists, storekeepers, new friends, relatives, and their audience to get insight into what is on every individual’s plate. To understand more about the food on the plates, they set to understand the origin of the food, how it is grown, where and how long it takes, or how far it comes from. Other details include how the food is prepared, the individual responsible for preparing it, and what happens after preparation, packaging, and leftovers.

In their pursuit to understand what people are consuming, they go to supermarkets, school lunchrooms, and fast food chains. In addition to that, they also delve into innovative sustainable food system initiatives by visiting green markets, farms, as well as community-supported agriculture initiatives. They find out that the initiatives assist the poor farmers in surviving and offer inexpensive and locally-cultivated food to individuals on the consumer end, particularly to lower-income urban communities. In the film, the two girl guides are formulating compassionate and sophisticated views on their society’s status and thus inspire active engagement and hope in other individuals.

The film surprised me when I realized that individuals could afford to eat healthily without paying much since it is inexpensive. When nutrition experts suggest the foods that people need to consume to live a better life, there is always an issue about how much certain foods cost. It is understandable, and since the pandemic started, many people have lost their jobs and are struggling financially (Gupta & Bharti, 2019). It is thus important to find ways that people can still consume healthy food at a low price or affordable. This would help convince more others as it allows an individual to eat healthily and save up more money, which people could use for other things.

The issue of obesity is among the top problems affecting many individuals in the world. Individuals in the medical field have tried to ensure that patients of various conditions, especially obesity, learn about eating healthy. Those who have improved on the kind of food they consume have managed to get better and defeat obesity (Gupta & Bharti, 2019). However, a group of individuals has not succeeded in their quest to defeat the condition. Through the film, Sadie and Safiya give us the blueprint of how individuals can deal with the issue of obesity and other conditions related to unhealthy eating. Another lesson is that people do not explore other ways of dealing with their issues.

Some markets can offer the right foods at a considerable price. Such information is important in the hospitality career because whatever someone is cooking and serving others will impact their health (Dietz & Santos-Burgoa, 2020). Having an individual who consumes food today and never comes back because they fell sick or developed a condition is not right. It is better when the food has a positive impact on the health of an individual. Therefore, finding markets that sell good quality food at an affordable price is the key to ensuring that I sustain customers for a longer time.

Understanding health and nutrition.

Health and nutrition are two important parts of our lives. Health is about how well our bodies are working. It’s about feeling good and being able to do the things we want to do. Nutrition is about the food we eat and how it helps our bodies work well.

The Importance of Good Nutrition

Good nutrition is very important for our health. Eating the right foods can help us grow strong and stay healthy. Fruits, vegetables, whole grains, and proteins are all good for us. They give us the energy we need and help our bodies work the best they can. Eating the wrong foods can make us feel tired and can make it harder for our bodies to fight off sickness.

How to Eat Healthy

Eating healthy is not always easy, but there are some simple things we can do. One is to eat a variety of foods. This helps make sure we get all the different nutrients our bodies need. We should try to eat lots of fruits and vegetables, and make sure to get protein, like meat or beans, every day. We should also try to limit foods that have a lot of sugar or fat.

Exercise is another important part of staying healthy. It helps our bodies stay strong and can also make us feel good. We should try to be active every day. This could be playing a sport, going for a walk, or even just playing outside.

The Role of Water in Our Health

Water is also very important for our health. Our bodies need water to work properly. We should try to drink plenty of water every day. It helps us stay hydrated, which is important for our bodies to work well.

Health and Nutrition Go Hand in Hand

Health and nutrition go hand in hand. Eating the right foods and staying active can help us stay healthy. It’s important to remember that it’s not just about looking good, but about feeling good and being able to do the things we want to do.

In conclusion, health and nutrition are very important parts of our lives. By eating the right foods and staying active, we can help our bodies work the best they can. This will help us stay healthy and feel good. Remember, your health is important, so take care of it by eating well and staying active!

This simple guide on health and nutrition is a good starting point for understanding how to take care of our bodies.

On Teens, Nutrition, and Exercise: How to Encourage Healthy Habits

Experts across Tufts outline the challenges for today’s teens when it comes to healthy eating and physical activity, and how parents and caregivers can help

Ask a teenager whether they’re eating healthy or getting enough exercise, and you might get a blank look.

With school getting more demanding, extracurricular activities multiplying, and college applications looming, teens have a lot going on. Many are also starting to work jobs, care for younger siblings, and take on other family duties–even amid drastic changes to their hormone levels and bodies, as well as their sense of who they are and their relationships with family and peers.

Dietitian Venus Kalami, N20

“It all comes together in a way that can be really wonderful, but also really overwhelming,” said Venus Kalami, N20, director of pediatric nutrition at the company Solid Starts, who has worked heavily with teens in her seven years of experience as a clinical dietitian.

Erin Hennessy , dean for research strategy and associate professor at the Friedman School of Nutrition Science and Policy at Tufts and director of the project ChildObesity180 , agreed. “In the order of things that teens have to be concerned about, nutrition and exercise are low,” she said.

But as a public health concern, they’re high on the list. Whether they know it or not, most teens are not meeting the Dietary Guidelines for Americans in major ways, according to Christina Economos , dean of the Friedman School and founder of ChildObesity180.

Christina Economos

They’re eating fewer fruits, vegetables, and whole grains, and more added sugars, saturated fat, and sodium than the guidelines advise. And only one in five adolescents are meeting the Center for Disease Control and Prevention’s guidelines for aerobic and muscle-strengthening activities (60 minutes of physical activity a day, 30 of them “vigorous”).

Due to demanding schedules and other factors, many teens find it difficult to eat regular meals and stay hydrated, Kalami said, which leads to lower energy levels and worse moods.

If not addressed, it can affect their health in the long run, too. Not building enough muscle and bone can lead to lower bone density in adulthood. Obesity in adolescence makes adult obesity almost 18 times more likely–and almost 30% of teens today have overweight or obesity, compared to 15% 60 years ago. On top of that, a record high 10% of U.S. households with children are food insecure, and rates of eating disorders among teens are on the rise. All this only got worse over the pandemic, with many parents out of work, teens stuck at home, and high levels of stress across the board.

But there are things that teens and the adults around them can do to promote healthier eating and more exercise, Tufts experts agreed–and there is reason for optimism, Hennessy added.

Erin Hennessy

“Over the past few decades as we’ve seen an increase in obesity rates, we have also seen a shift in interest among children, teens, and young adults who are becoming much more interested in food, food justice, agriculture, the environment, and how those pieces are interconnected,” Hennessy said. “They’re coming to us at the Friedman School with far more understanding and knowledge about the field than I’ve ever seen, and it’s great to see that kind of shift and personal engagement with those topics.”

Tips for vegetarian and vegan teens

Contrary to popular belief, kids and teenagers can be vegetarians or vegans and still eat a healthy, complete diet that meets all their nutrient needs.
Eating vegetarian or vegan does not automatically make for a healthy diet.
Cow’s milk is not less healthy than plant-based milks, and can play an important role in a healthy diet if you’re vegetarian but not vegan.
If you’re vegan, drink plant-based milks for calcium and vitamin D—particularly soy milk, which has high bioavailability of these nutrients.
Eat high-protein plant-based foods, such as nuts, beans, and seeds—quinoa is a great high-protein alternative to rice or pasta. Read the ingredients before buying meat substitutes, which can be high in added sugars and sodium.
Eat plant-based foods high in iron, such as beans and leafy greens. Try to consume vitamin C-rich foods (such as citrus fruits) at the same time to increase your iron absorption.
If you’re vegetarian, consume eggs and dairy to meet your vitamin B12 needs. If you’re vegan, consume nutritional yeast or B12-fortified products such as plant-based milks or yogurts.

Challenges for Teen Nutrition and Exercise

As children become teens, their energy and nutrient needs shoot up to an all-time high, because their bodies are growing. Particularly important for this growth are protein (for new tissue of all kinds), calcium and vitamin D (for bones), and iron, especially for those who are beginning to menstruate.

At the same time, teens’ schedules are getting busier, and their sleeping hours are shifting, leading to more barriers with eating regular meals and instead, leaning more on snacking. They are eating less at home, where parents might offer a healthy menu, and more with their friends or on their own–which leads to more fast food, processed snacks, soda, and sports drinks, especially at high schools with nearby convenience stores. “There’s a whole system that pushes the production, distribution, access, marketing, and palatability of unhealthy processed and ultra-processed foods ,” Economos said.

Teens’ higher order executive functions such as impulse control and long-term thinking are still developing, making it tougher to make nutritious choices in a landscape already skewed toward unhealthy options. And with adolescence comes greater self-consciousness about one’s body and eating, more scrutiny and comparison on social media, and increasing levels of judgment from a society with unrealistic expectations about body size and weight–adding an extra level of stress, which drives emotional eating.

“There are growth spurts that cause their height and weight to shift in ways they haven’t experience before,” Hennessy said. “They can feel like their bodies are no longer in their control, which can cause stress and anxiety.”

More teenagers are also struggling with food allergies or intolerances, or medical conditions requiring dietary limitations–and the stress that comes along with them. “We can see a lot of over-restriction out of fear of accidentally ingesting something,” Kalami said. “And this may affect social life, hanging out with friends, participating in team sport events, and many domains of life.”

On the exercise side of things, Hennessy pointed out that research shows teens—particularly those who identify as girls—are less physically active than younger children. It helps to have access to team sports, exercise programs, or any physical activity opportunity and the support for engaging in these opportunities. But it also takes an environment—like having green space and neighborhoods safe to walk in—to also be physically active. Many teens from marginalized communities don’t have this type of access, she said.

And even parents’ most well-meaning efforts to improve teens’ eating and exercise can backfire. Studies show that an authoritarian parenting style, or one that’s high in control (lots of rules, restriction and controlling parental behaviors) and low in responsiveness (a lack of openness, warmth, support), is correlated with disordered eating symptoms in youths up to 18 years old, and high-risk behaviors such as substance abuse.

“Some younger adolescents are more comfortable with the rules and structure that their parents create and lay down,” Hennessy said, referring to the developmental psychology concept of the legitimacy of parental authority. “But older teens especially feel there are particular domain areas that their parents should not be making rules about, like who their friends are, or the ways they move their bodies, or what they ingest.” This can cause tension between parents and their teens.

Tips for teens with food allergies and intolerances

Get the facts. If you suspect you have a food allergy or intolerance, visit an allergist for a blood test, skin prick test, or oral food challenge to determine what foods cause what reactions. If you were diagnosed a long time ago, visit an allergist again and see what treatment options may be available to you.
Don’t unnecessarily cut out foods. Over-restriction can also be problematic. If you can comfortably consume a food without having difficulties, keep doing so. Try not to cut out foods you don’t have reactions to.
With food allergies, take precautions . Read food labels and learn to properly interpret them. Ask about ingredients and cross-contamination potential at restaurants. Get an EpiPen prescription and always carry one in your purse or backpack, in addition to any other allergy medications; make sure your family or friends know how to administer it if you can’t (and what you’re allergic to).

Tips to Promote Better Nutrition in Teens

In light of these many factors, what can parents do to supporting teens in nourishing their bodies and finding forms of exercise that make sense for them? Tufts experts offered guidance ranging from being aware of specific nutrients, to including teens in food-related decision-making in the family.

Margie Skeer , interim chair of the public health and community medicine department at Tufts University School of Medicine , advised having regular family meals. Besides being linked to higher fruit and vegetable consumption and lower rates of disordered eating among adolescents, family meals have a protective effect against other high-risk behaviors, such as substance abuse.

It’s also essential to recognize the many forces in play beyond individual choice, and to approach nutrition and exercise as not solely the teen’s problem, but a function of the overall health of the teen’s family and the broader environmental context in which the family is situated, Hennessy said.

It’s essential to recognize the many forces in play beyond individual choice, and to approach nutrition and exercise as not the teen’s problem, but a function of the overall health of the teen’s family and environment, Hennessy said.

“How can we help teens develop a healthy relationship with food and movement, and create preferences that will carry them forward?” she asked. “How do we help create that foundation to return to throughout life for those who don’t have it, and how do we maintain it for those who do?”

Start with yourself. “How do I get my teen to go on a diet / exercise?” is a common online search phrase around teens and nutrition. But Hennessy suggested first stepping back and asking, “How am I role modeling healthy behaviors for my child?” and to shift the thinking from focusing on one child to thinking about the whole family and how the whole family can support and adopt healthy eating and movement behaviors.

Provide structure without being intrusive. Structure refers to the way parents organize their child’s environment to facilitate their child’s competence. What does that look like in practice? Setting rules and limits, providing limited or guiding choices, setting routines, role modeling, involving teens in food preparation and meal selection, and making healthy food available and accessible.

Know your teen’s nutritional needs. Consult a pediatrician or dietitian, Economos said, as well as resources such as the USDA’s MyPlate Nutrition Information for Teens . Pay special attention to whether your teen is getting enough dairy or plant-based dairy alternatives (for calcium and vitamin D), and iron sources such as red meat, beans, leafy greens, and fortified cereals.

Watch for changes and patterns. Rather than focusing on your teen’s size or weight, watch for new behaviors such as skipping meals, starting to eat much more or less, as well as higher stress levels around food, Hennessy said. Observe how often these behaviors repeat and provide support for your teen, and if there is ever a concern about certain behaviors, consult your healthcare provider.

Connect with your teen. Kalami has often asked about teenage clients’ passions and interests, which can provide the will and the ways to improve health. Skeer emphasized not just spending mealtimes with teens (ideally at least half of all meals), but making sure it’s quality time—meaning a relaxed, supportive environment with open communication and no distractions (such as phones). “Parents eating meals with teens conveys that spending time together is important to them,” Skeer said.

Empower your teen. Instead of prescribing healthy habits, learn your teen’s goals around eating–for example, being a vegetarian–and help them accomplish them in a healthy way, Hennessy said. Economos highlighted the importance of including kids in meal planning and preparation from a young age, teaching them culinary skills and healthy approaches to eating.

Look to local resources. Organizations like Girls on the Run can bring teenage girls together with supportive adults to walk, jog, and run in their neighborhoods, while local dance classes could introduce elements of culture and fun, Economos said. Teens can also get together to walk or train for a 5K, or take free online classes on yoga or strength training. “Goal setting as a group, and a structure where people care if you’re coming, can be really helpful,” Economos said.

Find one small change that works. Whether it’s swapping in nuts for potato chips, setting phone alarms to drink water, dancing to Zumba videos, or going to the park with a friend or family member, it’s the small, realistic changes that make a difference, Kalami said–and you can start with just one.

Support balance and variety. Encourage not just physical health, but overall “food-related quality of life,” said Kalami–especially among teens anxious about eating the wrong thing. “One of the main things I advocate for is minimizing unnecessary restriction, and loosening it up so we can get some flexibility, freedom, and variety back in our lives,” Kalami said.
