Purdue Nutrition Science researcher uncovers connection between hormones, gut microbiome and metabolic dysfunction commonly seen in postmenopausal women

Written By: Rebecca Hoffa, [email protected]

Hot flashes are one of the most commonly discussed side effects of menopause, but the decline of ovarian hormones and its effect on the gut microbiome can also increase the risk of a variety of metabolic diseases, including obesity and cardiometabolic syndrome, according to a recent publication by Tzu-Wen Cross , assistant professor in Purdue University’s Department Nutrition Science .

The novel study is the first to show the link between the gut microbiome and loss of ovarian hormones in increasing inflammation and metabolic disease risk, which may be relevant in postmenopausal women. This study was published by Gut Microbes in December 2023 and conducted as part of a National Institutes of Health T32 Training Program in Translational Cardiovascular Science during Cross’ postdoctoral work at the University of Wisconsin-Madison’s Cardiovascular Research Center.

“I was very intrigued by the interactions between the gut microbiome and sex hormones, with a particular focus on the diseases prevalent among postmenopausal women,” Cross said. “When women go through menopause, the drastic loss of ovarian hormone production can significantly impact health. There’s a cascade of metabolic changes, often leading to conditions like obesity and other metabolic diseases.”

In the recent study, Cross and her collaborators used a preclinical mouse model to explore the effects of high-fat and low-fat diets in combination with ovarian decline on metabolic health. After finding differences in the low-fat diet groups due to the loss of ovarian hormones that were further exacerbated in the high-fat diet groups, Cross then investigated the impact of transferring the gut microbes into a sterile, or germ-free, mouse model. In this model, they saw that the microbes associated with ovarian loss caused more inflammation and weight gain, which suggested a connection between the sex hormones produced by the gonads, or reproductive organs, and the gut microbiota, or the microorganisms within the gut environment.

Since those initial projects, Cross has expanded her research to encompass dietary elements pertinent to both the gut microbiome and sex hormone equilibrium. She is exploring dietary compounds that can be modified by the gut microbiome, impacting not only metabolic health but also gonadal development and fertility. Of particular interest is S-equol, which is a bacterial metabolite of a soybean-derived isoflavone. This metabolite, produced solely by intestinal bacteria, occurs in only some — but not all — humans, potentially contributing to health disparities.

“The work we published in Gut Microbes laid the foundation for my independent research group, as we began connecting the gut microbiome with the brain and gonadal axis,” Cross said. “Many sex hormones are produced through signals initiated by the brain. When we have sufficient estrogen or testosterone in our bloodstream, our brain and pituitary gland communicate to our ovaries or testes to stop production. This is how our body maintains homeostasis. The opposite is true when hormone levels are insufficient; the brain signals for increased production.”

In postmenopausal women, Cross explained, there is a decrease in estrogen, so the brain continues to signal for more production, leading to elevated neuropeptide levels, but the malfunctioning ovaries fail to respond. A project funded by a Purdue Ralph W. and Grace M. Showalter Trust grant led the researchers to believe the gut microbiome may be able to respond to these neuropeptides and the elevated neuropeptide levels could potentially alter the microbiota. Then, when this microbiota is transplanted, it carries the signal to communicate with the gonads.

“We have discovered that various metabolites, some generated by the gut microbiota directly, are responsive to sex hormone changes. We’re now delving into understanding the connections between these metabolites and inflammation,” Cross said. “These compounds could be the mediator driving the phenotypes we observed between the gut microbiota and inflammation, and potentially have an impact on puberty development and fertility, so I’m starting to work with reproductive biologists trying to get down to look at the developmental impact of gut microbiota and their metabolites on fertility throughout a person’s life span.”

Ultimately, Cross and her lab, including College of Health and Human Sciences graduate student Anna Organski, hope to influence future probiotic treatments and dietary recommendations to help reduce metabolic disease risk and fertility issues.

“The gut microbiota can directly alter sex hormone homeostasis through potential gut-brain communication, which could be valuable for treatments and therapeutics for certain sex hormone-sensitive conditions,” Organski said. “Hopefully the information we discovered can be used to investigate further therapeutics for other diseases as well.”

Cross stresses the importance of considering the influence of the gut microbiome on health when making dietary choices to not only feed the appetite but the gut microbiome as well.

“Our gut microbiota can affect aspects such as metabolism, highlighting the potentially significant impact on our overall health,” Cross said. “By being mindful of how different foods can affect the microbiome, we can make informed decisions that support our well-being.”

Personalised Nutrition

Food is at the heart of one of the biggest challenges of our time – how do we feed a growing population whilst managing the accelerated environmental degradation of our planet?

We urgently need to find solutions. It is important that everyone in the world has a right to eat balanced, healthy and nutritious food. At the same time, we need to make food consumption and production choices that reconcile the limited natural resources we have on our planet to feed everyone. We need sustainable nutrition.

Sustainable nutrition is defined as the ability of food systems to provide sufficient energy and essential nutrients to maintain good health of the population without compromising the ability of future generations to meet their nutritional needs. A sustainable diet, as described by the Food and Agriculture Organization of the United Nations, is a dietary pattern that promotes all dimensions of health and wellbeing; has a low environmental impact; is accessible, affordable, safe and equitable; and is culturally acceptable.

The multifaced challenge of providing adequate nutrition for a growing, global population while reducing negative environmental and social impacts is among the most urgent issues for our industry.

The Planet Challenge

It is well established that current means of global food production are straining the earth’s finite resources. About one third of global greenhouse gas emissions (GHG) are attributed to the food system, contributing to climate change which will impact the ability to efficiently produce food in the future. This is further compounded by deforestation, soil desertification and loss of biodiversity. Additionally, one-third of all food produced globally is wasted. This wastage not only squanders valuable resources but also worsens the challenge of feeding the world adequately.

The Nutrition Challenge

Today, there are about 2 billion men, women and children who are overweight or obese, while almost 735 million people suffer from malnutrition. The rise of diet related non-communicable diseases such as cardiovascular disease and type 2 diabetes is exponential, putting pressure on health systems and reducing quality of life. The global population is set to reach almost 10 billion people by 2050, emphasising the urgent need for change.

The Economic and Social Challenge

A systematic transformation in how we produce, consume and dispose of food is needed to feed the growing global population with food that is both nourishing and ecologically responsible. This can be done by focusing on nutrition, environmental health, social impact and economic sustainability.

Key considerations in sustainable nutrition for 2024

Food Based Dietary Guidelines (FBDG)

As we move towards a more sustainable way of producing food, it is important for food manufacturers and consumers to be mindful of the role that sustainable FBDGs play in the future of food production and consumption. Many governments globally have begun to incorporate sustainability into their country’s FBDGs, to encourage their population to choose diets’ that benefit their own health as well as the health of the planet. Denmark, Belgium, Italy and the UK have included messages such as the importance of eating meals rich in plants, decreasing meat consumption and reducing food waste. Designing food and beverage products with these FBDGs in mind may support consumers to adapt to more sustainable dietary practices.

Circularity and upcycling

Upcycled food uses ingredients that otherwise would not have gone to human consumption, is procured and produced using verifiable supply chains, and has a positive impact on the environment. Expect to see new waste streams identified and upcycled, as well as innovation in processes and ingredients used in upcycling (e.g., sterilisation of waste streams like spent grain or coffee).

Upcycling and Eliminating Food Waste: Closing the Loop

Quantifying sustainability impacts

The proliferation of eco-labelling and pending green claims regulations, alongside a significant momentum of net zero carbon commitments within the industry, has led to the requirement of robust environmental impact data at a corporate and a product level. Conducting life cycle assessments and product carbon footprints allow the sustainability impact of a product to be quantified and identifies areas for improvement. Many digital platforms are opening the opportunity for companies to carry out product assessments at scale. International standards for assessment and industry collaborations for collecting data from farm to fork are guiding improvements in the accuracy of these assessments.

What is a Life Cycle Assessment (LCA)?

Straight from our experts:  

‘Sustainable nutrition continu es to be a m egatrend within the food system because in order to ensure a sustainable supply of nutritious food for current and future populations, it needs to be considered with in every food and beverage innovation. Each of the ten H ealth and N utrition trends for 2024 are distinct in their own scientific advancements and product innovation, but each are connected through the lens of Sustainable Nutrition. ’ Dr. Aoife Marie Murphy, Sustainable Nutrition Manager, Kerry.

Women’s health refers to the unique physiological and nutritional needs of females throughout the various stages of the life course (adolescence, reproductive age, pregnancy, lactation, perimenopause, menopause and post-menopause). Each of these female life stages requires distinct nutritional recommendations to support overall wellbeing.

For example, adolescent females have an increased requirement for calcium to build lifelong bone density. A deficiency in calcium at this life stage can result in increased risk of osteoporosis post-menopause, when the protective effects of estrogen decline. Understanding the specific nutritional requirements at each female life stage has become popular for women, who are increasingly monitoring diet, menstrual cycle and lifestyle data using technology.

It is essential to continue to increase our understanding of the physiological differences between sexes, and determine how nutrition can support health, quality of life, sleep and exercise performance among women. There is evidence to show that the microbiome and gut motility of females also differs from males and may play a role in digestive symptoms, and there may be links between the gut microbiome and fertility, menopausal symptoms and breastfeeding. Nutrients and probiotics that support the microbiome will become even more important assets in addressing women’s health.

As we move into the era of precision nutrition research, using big data to understand gender-based differences will optimise nutritional interventions to support health. Technological innovations and increased investment mean that personalised nutrition, mental health support, reproductive technologies and holistic solutions for wellness will shape the future of the women’s health field.

The focus on addressing female-specific nutritional needs continues to grow with innovative product launches in supplements for pregnancy, breastfeeding, infertility, yeast & UTIs, menopause, pre-menstrual cycle symptoms, breastfeeding, stress/sleep, heart health, immunity and digestive health.

Key takeaways:

• Expect to see this trend accelerate in the near future – with more clinical research into female-specific conditions and the growing capabilities of precision nutrition, there will be evolving evidence to support women’s health through diet.
• Certain plant-derived compounds have potential to support female specific conditions. For example, inositols from corn and carob fruit have been clinically proven to support hormonal and metabolic balance in the female reproductive cycle. Specific phytoestrogens from plants have also been shown to regulate menopausal symptoms such as hot flushes. Supplements positioned for female health are continuing to grow globally.
• Wearable devices and apps are allowing women to know more about what’s happening in their bodies and to better understand the symptoms they experience. This allows them to make decisions about the consumption of specific diets and functional ingredients to meet their needs.

Straight from our experts:

“There is a growing recognition of the unique health needs of women and a shift toward prioritising women’s well-being. This increased awareness and advocacy have created a demand for more comprehensive research and solutions. With women’s health spanning from adolescence to old age, innovative technologies, treatments and products are being developed to address various aspects of women’s health and fertility.” – Dr. Monica Maria Olivares, RDA Director for Women’s Health, Kerry

Microbiome – Beyond Digestive Health

The length of the gastro-intestinal tract (GIT) varies from person to person, but on average, it’s about 20 feet long. It starts in the mouth, continues with the esophagus, stomach and small and large intestine and ends up by the anus. Along the way, there about 40 trillion microorganisms – bacteria, viruses, fungi, protozoans and archaea – living in the downy meanders of the microvilli lining the GIT.

The gut neuromicrobiology is an emerging field of research for scientists that want to better understand the mode of actions of the gut-brain axis (BGA). An increasing amount of evidence highlights that modifications of gut ecology and its metabolic activity are associated to many neurological disorders such as brain function, neuronal development, stress, anxiety, mental state and emotional regulation. Gamma-amino butyric acid (GABA), serotonin, dopamine, and norepinephrine are neurotransmitters that are synthesized by some gut bacteria and can be the actors involved in this BGA. Others bioactives include tryptophan, or glutamate and their metabolites, short-chain fatty acids and the pool of bile acids. This broad spectrum of neuroactive compounds and the gut microbiome is unique to each of us and can be affected by lifestyle, diet, genetic make-up, lack of exercise, and medications that we consume. Thus, to (re) balance a disturbed gut microbiome, personalization of the microbiome modulators – probiotics, prebiotics, synbiotics, postbiotics, psychobiotics, etc. – will be critical. This is where machine learning, artificial intelligence, and tools to analyze massive datasets will be of utmost importance to unlock the full potential and allow these technologies to really support our gut microbiome.

• The gastro-intestinal tract is very long and comprised a myriad of microorganisms that are embedded in the gut lining, called the gut microbiome.
• The gut microbiome transforms nutrients and synthesises metabolites that may affect brain health and other targets beyond the gut.
• Personalization of the gut microbiome modulators will be critical to get the full benefits of these technologies.

“Within the 20 feet of our gastro-intestinal tract, trillions of microorganisms are shaping not just digestion but influencing our mind, emotions and brain. The gut’s unique microbial composition, a personalised composition of bacteria and their neuroactive compounds, is influenced by our lifestyle, diet and genetics. To harmonise this delicate balance, the future lies in the precision of personalised microbiome modulators, where machine learning and AI unlock the secrets of our gut’s intricate composition.” – Dr. Mathieu Millette, Ph.D., Mcb.A.

Postbiotics – What Are They and How Are They Different From Other -Biotics?

Global circumstances like war and COVID-19 are driving inflation and placing friction between the strong desire of consumers to eat healthy and sustainable food and their ability to afford it. These factors have contributed to a growth in the number of people who are undernourished globally, which is estimated to have grown by 28% between 2017 and 2023 (from 572 million to 735 million people, ).

As we work to develop food systems and food consumption patterns that are healthier, socially accepted and generate positive environmental impacts, we must ensure that the nutrition solutions we develop are affordable and accessible to society as a whole.

Research indicates that some consumers are willing to pay more for foods with lower environmental impact, however the percentage of the population able to afford this remains small and price remains the top priority for consumers. Since demand for healthy food remains high, we see a focus on “affordable nutrition” innovation in new ingredients, foods and beverages that provide a health benefit but at a lower cost.

• With a growing population, mainly in developing countries, foods that deliver affordable nutrition with minimal environmental impact are necessary.
• Dietary diversity could support the affordability and stability of the food system. Today, 75% of humanity’s food is generated from only 12 plants and 5 animal species. This makes our food supply incredibly vulnerable to disruptions in these few food sources (e.g., natural disaster, disease, war).
• Innovating products that achieve maximum nutrition value with lowest cost and environmental impact is necessary. Taste and sensory knowledge are a hidden opportunity – a broad knowledge of masking the off-notes of different protein types can allow flexibility in raw material sourcing as costs fluctuate.
• Whole grains, egg, dairy, fruits and vegetables are nutritionally dense and can be the best sources of nutrition, per dollar. Beans are a prime example of an inexpensive food that provides fiber, protein, minerals and calories.

  Straight from our experts:  

“Food systems cannot be deemed sustainable if the food is unaffordable to the majority of the population. Food innovation needs to focus on how can we make the food system more economically sustainable by maximising the nutritional density and affordability of a wide variety of foods to nourish communities globally.” – Roisin Murphy, Responsible Sourcing Manager, Kerry

Sodium and Sugar Reduction

Sugar and sodium reduction have been on nutrition trend lists for years, but a few key factors are expediting the pace of change as the food industry reformulates for healthier products.

For example, the World Health Organisation (WHO) continues to call on businesses and governments to reduce the risk of non-communicable diseases, malnutrition and obesity, including a reduction in consumption of salt and a reduction of saturated fats, sugars and calories. The WHO 2023 global report on sodium intake reduction shows that the world is off-track to achieve its 2013 global target of reducing sodium intake by 30% by 2025. Implementing highly cost-effective sodium reduction policies could save an estimated 7 million lives globally by 2030.

In addition, governments worldwide are introducing more and more legislation and initiatives to encourage healthier diets.

• Taxes on foods high in sugar or salt – More countries are implementing taxes on sugar-sweetened beverages, high sugar foods or high salt foods. In December 2022, WHO called on more countries to place taxes on sugar-sweetened beverages.
• Legislation  – Countries including Brazil, Mexico, Singapore and the UK continue to add legislation that places limits or penalties on foods and drinks high in saturated fat, sugar or salt (HFSS). According to the 2023 WHO Sodium Country Scorecard , more than a quarter of the world’s population lives in countries with mandatory measures towards sodium reduction, including mandatory declaration of sodium.
• Front-of-pack labeling  – Labels that penalise foods on front-of-pack for high sugar or salt content, such as the Health star rating in Australia/New Zealand or the Nutri-Score in many European countries, are rising up in more countries each year. There has been a 69% growth year-over-year in food and beverage launches sporting a regulated nutrition warning label (Innova trends). In 2023,  Canada introduced a front-of-pack nutrition symbol which is required on foods high in sugar, sodium and saturated fat. The United States are  exploring options  to standardize front-of-pack labeling with the US FDA spending much of 2023 testing consumer’s understanding of both black/white and color schemes through focus groups. The European Union is also set to propose a  unified front-of-pack labeling scheme for all member states in 2024 .

Reformulation to reduce sugar and sodium in foods comes with challenges around taste, functionality, food safety, cost and consumer acceptance. Stealth reformulations reducing sodium or sugar in small increments can achieve up to 10% reductions, however achieving a higher reduction while maintaining consumer acceptance requires innovation in the area of taste modulation. Recent advancements leverage contemporary taste and smell neuroscience and state-of-the-art fermentation technologies. To learn more, see KHNI webinar – Solving Sodium .

• Governments worldwide are introducing more and more legislation and initiatives to encourage healthier diets.   
• Consumers are becoming more health conscious, resulting in an increase in front of pack signposting.  
• Differing front of pack labelling and marketing restrictions across countries will make it more difficult for companies to sell products across several countries.  
• Decreasing nutrients of concern while maintaining taste, functionality and shelf life are challenging and require innovation in taste modulation and food science.  

“Changes in nutrition and labelling legislation are becoming more widespread, and consumers are becoming more health conscience. Front-of-pack signposting is becoming more widespread to make healthier choices more simple but is also driving the increasing need for innovative technology to help manufacturers create healthier, more sustainable products, that deliver on taste and experience.” – Pattie O’Keeffe, BSc, RNutr, Sustainable Nutrition Manager at Kerry

“Recent global events have highlighted the enormous cost to health services and governments – and where to invest in public health service – so it is likely that more pressure will be placed on the food industry to make further step changes in sodium reduction in multiple food categories to improve the outcomes of global populations.” – Dr. Kay Marshallsay, Global Portfolio Director – Fermented Products, Kerry

Despite challenges, there are significant opportunities in the plant-based market.

Meaningful changes to the way we eat will continue, but may be slower and take longer than was first thought. Flexitarianism is still the most common dietary approach, indicating an ongoing mainstream acceptance of plant-based meat alternatives. But as plant-based evolves, we need to continue to drive engagement and ensure plant-based products deliver on

We know that taste is the most important reason consumers will choose a plant-based product, and that taste is the main reason consumers will reject plant-based foods. Taste is missing in some plant-based categories more than in others – e.g., cheese vs milk – which spells opportunity for brands that can solve for it.

Health and nutrition is also a major driver in this relatively young category, with a need to move away from long ingredient decks and toward ingredients that deliver positive health benefits and associations. For example, a recent study we commissioned in Europe found that 60% of plant-based consumers view plant-based foods as healthier, so there is a need to make this a reality across applications.

Sustainability is also important to a growing number of consumers, with 60% of plant-based consumers from our European study saying they are positively influenced by the lower emission and resource intensity of plant-based options.

Despite these growing needs of the plant-based consumer, it is still essential to keep costs down.

Key Takeaways

• The plant-based category is still ripe with opportunities, but the meteoric growth has slowed.
• Taste is the main reason consumers choose a product – and is also the top reason products are rejected – highlighting the need for improvements in palatable plant-based test.
• A majority of plant-based consumers believe plant-based products are healthier than traditional products, but innovation in the space is needed to ensure foods and beverages deliver.
• Other considerations to keep in mind are the importance plant-based consumers place on sustainability as well as the need to keep costs competitive.

Straight from our experts

“First and foremost, we need to further develop plant-based products that perform sensorially and nutritionally at an accessible price point. ​I’m excited by the ‘meat plus’, space: real meat crafted with cereal and vegetables that deliver added nutrients with Nutri-Scores up to even A or B being possible. These products will combine the real taste of meat with plant-powered benefits, delivering taste, succulence, texture and added nutrients while also being more sustainable. It’s been done before, albeit before the consumer was ready and with poor product delivery. From what I’ve seen within our business, this could be the future or at least until the huge investment in cultivated meat comes good!” – David Hamilton, Global Creative Insight Officer, Kerry

The Unique Considerations for Food Safety & Shelf Life in Plant-Based Meat Alternatives

Globally, people are becoming more proactive about their health as a means to live longer and maintain quality of life as they age. One trend emerging from this is the focus on recovering and bouncing back from stressors on the body such as illnesses like cold and flu and muscle damage and inflammation from exercise. The role of specific nutrients in enhancing the management of mental stress is also gaining attention. For example, adaptogenic herbs and spices like turmeric and ashwagandha, are being explored for their potential stress-reducing properties.

Overall immune health is closely linked to this trend: 69% of consumers in a FMCG Gurus report said they gauge their immune health by how quickly they recover from illness.

In addition to diet, staying active is key to supporting a healthy lifestyle. However, exercise can cause stress on the joints and generate oxidative stress and inflammation, both of which can damage muscles and impact recovery. Studies suggest immune cells may prevent muscle damage by lowering levels of pro-inflammatory markers which, when over-stimulated, can drive chronic inflammation and aging.

Ingredients that are clinically documented to interact with these markers and help reduce exercise-induced inflammation – such as botanical extracts, collagen and omega-3s – are proving successful in this area. A balanced diet rich in anti-inflammatory foods such as berries, fatty fish, nuts and green leafy vegetables can also significantly reduce inflammation and aid in muscle and joint recovery. The role of antioxidants found in fruits and vegetables in combating oxidative stress — a key factor in recovery — is in need of further study.

• Consuming a diet rich in anti-inflammatory is crucial for reducing inflammation and aiding in muscle and joint recovery. Antioxidants combat oxidative stress, a key factor in the recovery process, particularly after exercise or physical exertion.
• Specific nutrients play a significant role in managing mental stress. Stress is directly related to the body’s ability to recover, so managing it thought dietary changes and supplements shows promise.
• Immune health plays many roles in recovery such as regulating inflammation, supporting muscle repair and overall health and vitality.

“The trend of recovery is deeply intertwined with nutrition and dietary choices. As consumers become more informed, there is an increasing demand for foods and supplements that support various aspects of recovery — from immune and joint health to stress management.” – Dr. Niamh Hunt, PhD, Senior Global Marketing Manager – Immune and Joint Health, Kerry .

Protein Production’s Future

A few examples include:

• Cultivated meat, or the production of muscle and fat tissue from cells grown in vitro or outside of a living organism under controlled conditions to yield a protein-rich tissue. This field is in constant development and could reduce land use required to produce meat by  up to 99% . Recent innovations have substantially driven down the average cost of producing a cultured meat patty, from US$1 million per kg in the year 2000 down to about US$100 per kg in 2020, according to Rethinkx – Rethinking Food and Agriculture . This is expected to fall to less than US$10 per kg by 2025, making cultivated meat cost-competitive with traditional beef.

• Precision fermentation, which uses microorganisms to produce specific proteins or other compounds. Fermentation has been used in food production for thousands of years, but recently advancements, such as precision fermentation, make it possible to produce milk proteins among other products.
• Enzyme engineering, which has been used in food production for centuries. This technique offers multifaceted benefits such as operational efficiencies, improved product quality, extended shelf life, waste valorisation and nutrient unlocking. Scientists are only beginning to tap into the vast potential of enzymes, with a small fraction currently utilised. The ongoing focus on health, sustainability and enzyme optimisation indicates a positive disruption in the food system, promoting efficiency and sustainability.

To transform food production, the industry seeks novel functionalities through directed evolutionary biotechnological processes. This includes optimising enzymes through bioengineering to create healthier, tastier products with reduced environmental impact. Enzyme engineering allows the modification of properties like activity, selectivity and stability through changes in amino acid sequences.

These technologies promise enhanced agricultural efficiency, reduced food waste and the creation of healthier, more sustainable products. Overcoming challenges in consumer acceptance and regulatory compliance requires collaborative efforts between scientists, bioengineers and regulatory bodies. The fusion of enzyme engineering with cutting-edge bioinformatics opens new frontiers, paving the way for a future where sustainable nutrition becomes a reality.

Key takeaways

• Rapid developments in enzyme and strain engineering, precision fermentation, artificial intelligence, big data and agri-tech have been adopted by a new generation of scientists, fueled by the purpose of creating a sustainable food system.
• Cross collaboration and ventures within the food industry – together with influence on governmental action – is required to drastically improve and accelerate the acceptance of new-to-market protein alternative technologies.
• Consumer acceptance of alternative proteins will require continued improvements in sensory attributes. This places a significant demand on innovation efforts in disciplines including fats, cell line developments and biochemical improvements to plant proteins in order to develop products accepted by consumers.

“Rapid advancements in bioengineering and big data are transforming the food industry and disrupting the way in which we produce food. I believe more efforts must be taken to prepare the careful introduction of these new products to the market – we do not know yet how consumers will adopt these novel foods.” – Dr. Niall Higgins, PhD, Business Development Manager – Enzymes, Kerry

From a scientific perspective, it is more and more evident that we are actually not all born equal, with respect to our physiology and health needs. Health needs differ by person, and they change throughout life. Gender, age, ethnicity and life phases such as pregnancy or menopause all influence required nutritional support.

Consumers are searching for personalised advice and personalised nutritional solutions backed by scientific rationales. The scientific community has a keen interest in these topics as well, as the overall conviction is that personalised approaches towards health benefits will be more effective than general ones.

For example, scientists are trying to better understand the impact  ourindividual microbiome has on the way our body reacts to foods. At the same time, ever more affordable test kits are giving consumers a better understanding of their unique metabolism and microbiome. Combining this personal biological data with that of digital health trackers is creating powerful datasets that can guide dietary choices and supplement use to help consumers recieve desired health benefits.

The science of personalised nutrition is growing and holds promise for the future, enabling a more effective approach to human health.

• Acknowledging that individuals have unique physiological and health needs influenced by factors such as age, gender and life phases like pregnancy or menopause is the cornerstone of personalised nutrition
• There is demand for personalised nutritional solutions supported by scientific rationale, as both consumers and the scientific community recognise the potential effectiveness of tailored health approaches.

“ 2024 will see the rise of personalised nutrition, acknowledging our diverse health needs. Backed by science, this trend considers individual factors like age, gender and the microbiome. Consumers seek personalised advice, empowered by the fusion of personal biological data and digital health tracking. It’s a revolutionary approach, recognising that nutrition and health are specific and unique .” – Alexandra Boelrijk, Global RD&A Senior Director – ProActive Health, Kerry

Globally, approximately 250 million people suffer from vision loss and impairment which can have a significant impact on quality of life. Leading causes include cataract, AMD, glaucoma and diabetic retinopathy. These conditions mostly affect older adults, and with our ageing population the number of affected individuals is anticipated to increase exponentially over the next decade.

Simultaneously, as the world becomes increasingly digital and with the rise of e-gaming, younger consumers are finding themselves immersed in screens for extended periods, which is also driving interest in supporting eye health.

As individuals recognise the significance of maintaining optimal vision and preventing eye-related issues, eye health support now includes recommendations including  dietary changes, supplements, blue light blocking technologies (such as glasses and screen filters) and lifestyle strategies such as the 20-20-20 rule, which advises digital device users take a 20-second break to look at something 20 feet away every 20 minutes to helpalleviate eye strain.

The eyes are particularly sensitive to oxidative stress, because they use a lot of oxygen, have high levels of specific types of fatty acids and get a lot of exposure to intense light. This combination of factors can lead to the creation of reactive oxygen species, causing damage to the eye tissues. Consequently, there has been significant research interest in the potential benefits of antioxidant vitamin and mineral supplements, with vitamins such as A, C and E being suggested as a simple and cost-effective strategy for preserving eye health. Additionally, because the eye has a high fatty acid composition, omega-3 fatty acids have been shown to be important for the development and maintenance of eye tissue.

Incorporating a diverse range of fruits and vegetables, nuts, seeds, and fish into one’s diet is another tactic gaining popularity as a proactive measure to sustain healthy eyes. Here are eight commonly recommended consumables for eye health.

A holistic lifestyle approach is emerging as a key component of this trend. Beyond nutrition and screen habits, individuals are recognizing the importance of regular eye check-ups, achieving adequate amounts of sleep, managing chronic conditions like diabetes, and avoiding harmful behaviors, such as smoking, as integral components of comprehensive eye care. This understanding of the interconnectedness of various lifestyle factors provides individuals with a more holistic and proactive approach to preserving their vision.  

Key Takeaways  

• The connection between nutrition and eye health is becoming more evident, with an increasing number of studies highlighting the importance of specific nutrients. A growth in supplements supporting eye health will help fill the gap in nutrient-rich diets for vision.
• With the widespread use of digital devices in both personal and professional spheres, concerns about digital eye strain have intensified and consumers are taking a proactive approach, seeking out fortified foods and supplements as well as blue light blocking technologies to preserve their long-term vision.
• Holistic Lifestyle Approaches: Understanding the interconnectedness of various lifestyle factors provides individuals with a more holistic and proactive approach to preserving their eye health.

Study finds resistance to critically important antibiotics in uncooked meat sold for human and animal consumption

by European Society of Clinical Microbiology and Infectious Diseases

New research presented at the ESCMID Global Congress (formerly ECCMID) in Barcelona, Spain (27–30 April) has found substantial levels of resistance to critically-important antibiotics in meat sold for human and animal consumption. The study is by Dr. Jordan Sealey, Professor Matthew Avison and colleagues from the University of Bristol, UK.

Meat sold for consumption by humans and companion animals in the UK is regulated by the UK Government Food Standards Agency (FSA) to ensure it falls within bacterial limits deemed safe. However, while meat is tested for the types and amounts of pathogens present, it is not tested for resistant opportunistic pathogens (e.g. Escherichia coli).

Multiple studies have shown a strong association between feeding dogs a diet of uncooked meat (raw dog food) and an increased risk of excreting E. coli resistant to critically important antibiotics in their feces. It is possible that pet animals eating raw meat increases the risk of spreading resistant pathogens to their human owners in the household.

Here, the authors investigated 58 samples of uncooked meat (15 each of beef, chicken, lamb and 13 of pork) sold for human consumption after cooking (MHC) and 15 samples of chicken-based raw dog meat (RDM) for resistant E. coli.

Samples were enriched and plated onto agar containing common antibiotics—amoxicillin, amoxicillin-clavulanate, cefotaxime, ciprofloxacin, spectinomycin and streptomycin, of which some are considered critically important for human health, to test for resistant E. coli.

The team found the highest sample-level positivity rate for resistant E. coli in uncooked meat for human consumption was in chicken—100% of samples were positive for resistance to spectinomycin and streptomycin, and 47% of samples were positive for resistance to critically important fluoroquinolones. For lamb, pork and beef the values were 27%, 38% and 27% for spectinomycin, 40%, 38% and 47% for streptomycin and 7%, 8% and 13% for fluoroquinolones, respectively.

Similar levels of resistance were seen in chicken raw dog food samples as seen in chicken meat; 87% positive for spectinomycin and streptomycin resistance, and 47% for fluoroquinolones. Sample level positivity for resistance to critically important cefotaxime was 27% for raw dog food.

The authors say, "While most people know that if they don't use proper hygiene when handling uncooked meat they can pick up ' food poisoning ,' most people are not aware that you can also pick up antibiotic-resistant opportunistic pathogens. Owners who feed their dogs raw dog food perhaps don't realize this uncooked meat also contains these pathogens and maybe don't use proper hygiene after preparing the meat, and don't consider their dog as a potential source of these pathogens if it is raw fed."

The most common STs in raw dog food were ST10, ST162, ST744—in the authors' previous study on fluoroquinolone resistance in dogs, excretion of these STs was found to be strongly associated with dogs being fed a raw food diet.

The authors conclude, "This study confirms that uncooked meat carries multiple resistant E. coli, commonly including resistance to critically important antibiotics important for human health. If ingested, these bacteria can enter the gut, and may cause resistant opportunistic infections (e.g. urinary tract infections) in the future. It is therefore very important that people cook meat thoroughly before eating, and use appropriate hygiene practices during meat preparation.

"Our findings that raw dog food is similarly contaminated with resistant bacteria provides an explanation for why dogs fed raw meat are more likely to excrete these bacteria. Appropriate hygiene practices after handling raw dog food, and dogs that are fed such raw meat , are strongly advised."

Are We Evolving? New Research Reveals That Human Brains Are Getting Larger

By University of California - Davis Health April 22, 2024

Recent research shows that human brains have grown in size over generations, potentially reducing the risk of dementia, with health and educational advancements playing a significant role in this increase.

Recent research indicates that brain size has been progressively enlarging in individuals born post-1930s.

A recent study conducted by researchers at UC Davis Health has revealed that human brains are increasing in size. According to the study, individuals born in the 1970s exhibited brain volumes that were 6.6% larger and brain surface areas nearly 15% greater than those of people born in the 1930s.

The researchers hypothesize the increased brain size may lead to an increased brain reserve, potentially reducing the overall risk of age-related dementias.

The findings were published in JAMA Neurology .

“The decade someone is born appears to impact brain size and potentially long-term brain health,” said Charles DeCarli, first author of the study. DeCarli is a distinguished professor of neurology and director of the UC Davis Alzheimer’s Disease Research Center. “Genetics plays a major role in determining brain size, but our findings indicate external influences — such as health, social, cultural, and educational factors — may also play a role.”

75-year study reveals brain changes between generations

The researchers used brain magnetic resonance imaging (MRIs) from participants in the Framingham Heart Study (FHS). The community-based study was launched in 1948 in Framingham, Massachusetts, to analyze patterns of cardiovascular and other diseases. The original cohort consisted of 5,209 men and women between the ages of 30 and 62. The research has continued for 75 years and now includes second and third generations of participants.

The MRIs were conducted between 1999 and 2019 with FHS participants born during the 1930s through the 1970s. The brain study consisted of 3,226 participants (53% female, 47% male) with an average age of about 57 at the time of the MRI.

The research led by UC Davis compared the MRIs of people born in the 1930s to those born in the 1970s. It found gradual but consistent increases in several brain structures. For example, a measure that looked at brain volume (intracranial volume) showed steady increases decade by decade. For participants born in the 1930s, the average volume was 1,234 milliliters, but for those born in the 1970s, the volume was 1,321 milliliters, or about 6.6% greater volume.

Cortical surface area — a measure of the brain’s surface — showed an even greater increase decade by decade. Participants born in the 1970s had an average surface area of 2,104 square centimeters compared to 2,056 square centimeters for participants born in the 1930s — almost a 15% increase in volume.

The researchers found brain structures such as white matter, gray matter and hippocampus (a brain region involved in learning and memory) also increased in size when comparing participants born in the 1930s to those born in the 1970s.

Larger brains may mean a lower incidence of dementia

According to the Alzheimer’s Association, approximately 7 million Americans are currently living with Alzheimer’s disease. That number is expected to rise to 11.2 million by 2040.

Although the numbers are rising with America’s aging population, the incidence of Alzheimer’s — the percentage of the population affected by the disease — is decreasing. A previous study found a 20 percent reduction in the incidence of dementia per decade since the 1970s.

Improved brain health and size may be one reason why.

“Larger brain structures like those observed in our study may reflect improved brain development and improved brain health,” DeCarli said. “A larger brain structure represents a larger brain reserve and may buffer the late-life effects of age-related brain diseases like Alzheimer’s and related dementias.”

One of the study’s strengths is the design of the FHS study, which allows the researchers to examine brain imaging of three generations of participants with birthdates spanning almost 80 years. A limitation is that non-Hispanic white participants make up the majority of the FHS cohort, which is not representative of the U.S. population.

3 comments on "are we evolving new research reveals that human brains are getting larger".

Remember why big brains in the first place. Humans are both highly cooperative AND fiercely competitive. Gains from cooperation are balanced against thefts from defection/competition. So we enjoy gains, whilst keeping a wary eye on the partner. Big brains let us evaluate when the other will cooperate OR defect. We evolved to know when to keep playing or quit.

This is much too fast for evolution to be a likely cause. It’s only three or four generations. The likely cause is improved diet and nutrition, and possibly improved sanitation and other health measures. It’s consistent with the broad increase in IQs and height observed over the last 150 years or so, which is likewise thought to be primarily due to improved diet and nutrition.

Having brains get larger in order to store more Ads and and other worthless information is hardly evolving. The human mind peaked around the era of Socrates. Humans these days are stunted mental midgets.

The effects of cannabidiol and its main metabolites on human neural stem cells

2023 FDA Science Forum

Cannabidiol (CBD) is used for a variety of purposes by different groups of people, including to reduce nausea in pregnancy. In recent years, demand for CBD or CBD containing products has increased at an alarming rate. When consumed during pregnancy, CBD can pass through the placenta and enter the fetal blood stream. There are concerns about the effects of CBD and its major metabolites (7-OH-CBD and 7-COOH-CBD) on fetal development. In the present study, human neural stem cells (NSCs) were treated with CBD and its metabolites at different concentrations and durations to understand how the drug may affect fetal brain development. Drug effects on NSC viability and proliferation rate were assessed using MTT reduction, LDH release and EdU incorporation assays. Cell cycle analysis was performed using flow cytometry after cellular DNA was stained with propidium iodide. CBD, 7-OH-CBD and 7-COOH-CBD dose-dependently reduced NSC viability. At clinically relevant concentrations (i.e. human plasma concentrations), CBD, 7-OH-CBD and 7-COOH-CBD caused more obvious cell death when exposure duration increased. CBD and 7-OH-CBD reduced NSC numbers in the G1 phase after 24h exposure. However, 24h exposure did not cause significant change in NSC proliferation. This study demonstrates that clinically relevant concentrations of CBD, 7-OH-CBD and 7-COOH-CBD affect basic physiological features of human NSCs, suggesting the drug may have adverse effects on the developing human brain in vivo.

Proper nutrition offers one of the most effective and least costly ways to decrease the burden of many diseases and their associated risk factors, including obesity. Nutrition research holds the key to increasing our understanding of the causes of obesity and its related comorbidities and thus holds promise to markedly influence global health and economies. After outreach to 75 thought leaders, the American Society for Nutrition (ASN) convened a Working Group to identify the nutrition research needs whose advancement will have the greatest projected impact on the future health and well-being of global populations. ASN’s Nutrition Research Needs focus on the following high priority areas: 1 ) variability in individual responses to diet and foods; 2 ) healthy growth, development, and reproduction; 3 ) health maintenance; 4 ) medical management; 5 ) nutrition-related behaviors; and 6 ) food supply/environment. ASN hopes the Nutrition Research Needs will prompt collaboration among scientists across all disciplines to advance this challenging research agenda given the high potential for translation and impact on public health. Furthermore, ASN hopes the findings from the Nutrition Research Needs will stimulate the development and adoption of new and innovative strategies that can be applied toward the prevention and treatment of nutrition-related diseases. The multidisciplinary nature of nutrition research requires stakeholders with differing areas of expertise to collaborate on multifaceted approaches to establish the evidence-based nutrition guidance and policies that will lead to better health for the global population. In addition to the identified research needs, ASN also identified 5 tools that are critical to the advancement of the Nutrition Research Needs: 1 ) omics, 2 ) bioinformatics, 3 ) databases, 4 ) biomarkers, and 5 ) cost-effectiveness analysis.

INTRODUCTION

The attainment of good nutrition depends on and encompasses the entire food supply. Plant and animal foods and their various components are the primary vehicles that provide nourishment to human beings. Nutrition is vital, not only in the growth and development of humans and animals but also in the prevention and treatment of disease. Nutrition is also fundamental to the maintenance of good health and functionality. Basic and applied research on the interrelations between nutrition and noncommunicable diseases, nutrient composition, and nutrition monitoring represents the underpinnings for healthy populations and robust economies. Thus, innovative nutrition research and education provide the basis for solutions to larger health-related issues, allowing individuals to live healthier, more productive lives.

The importance of nutrition, as an integral part of the solution to many societal, environmental, and economic challenges facing the world, has just started to be fully appreciated. The American Society for Nutrition (ASN) has identified the “grand” challenges facing nutrition research and science in the 21st century, termed “Nutrition Research Needs.” Findings from these Nutrition Research Needs will elucidate strategies that can be applied toward the prevention and treatment of both infectious and noncommunicable diseases, including cardiovascular disease, diabetes, and cancer. Nutrition research holds the key to increasing our understanding of the underlying causes of obesity and its related comorbidities and thus holds promise to markedly influence global economies. Knowledge about adequate nutrition also has an important role in reducing or ending global and domestic food insecurity through direct and purposeful agricultural practices. Population growth will undeniably lead to increased global demand for a safe, available, sustainable, and affordable food supply, while continuing to demand nutritional adequacy.

The ASN Nutrition Research Needs project was originally conceptualized by ASN’s Public Policy Committee to identify worldwide nutrition research needs. This effort will be used to educate and communicate to policy makers and other stakeholders the need and value of increased nutrition research funding to meet societal needs. ASN’s Public Policy Committee reached out to nearly 75 thought leaders in September 2011 to develop a draft list of nutrition research needs.

In February 2012, ASN convened a Working Group of nutrition scientists and researchers representing a cross-section of the Society’s membership to determine the nutrition research needs that will have the greatest impact on the health and well-being of global populations. The names of the Working Group members are listed in the Acknowledgments. Starting with the draft list, the Working Group narrowed down and pulled together 6 nutrition research needs for which advancement would have the greatest projected impact on future health and well-being.

The ASN then informed its membership of the 6 priority research needs and sought further member input. A workshop was held during ASN’s 2012 Scientific Sessions and Annual Meeting in San Diego, CA, with nearly 250 attendees. The research needs were also shared via ASN’s member newsletter, which reaches the entire membership base of nearly 5000 individuals, to inform and seek input from members who did not attend the annual meeting or the workshop. Member feedback on the Nutrition Research Needs was incorporated during development of the final document.

THE TOP NUTRITION RESEARCH NEEDS

The top 6 nutrition research needs cut across the entire research spectrum from basic science to health policy, from discovery to application. Specific research areas are listed under each research need. These 6 nutrition research needs are highlighted in the hope that they will prompt scientists from all disciplines to collaborate to advance these challenging research needs that have high potential for translation and public health impact. Although the topics presented focus principally on human nutrition research, the Working Group recognized that nutrition research using animal models is an essential foundation for making new discoveries that can be translated to advances in human nutrition. Further, the importance of animal nutrition research is emphasized within these research needs in particular: “Understanding the role of nutrition in health maintenance” and “Understanding the food supply/environment.” The research community will benefit from clearly articulated nutrition research priorities that will lead to science-based information, help to shape policy and enhance future funding for nutrition research, and thereby further promote the field of nutrition science.

1) Understanding variability in individual responses to diet and foods

A top priority for future nutrition research is the need to better understand variability in metabolic responses to diet and food. Enormous variability exists in individual responses to diet and food components that affect overall health. Discoveries underpinning this variability will lead to advances in personalized nutrition interventions and will better inform health and food policies, including Dietary Reference Intakes (DRIs) for nutrient needs and, ideally, future recommendations for known bioactive food components. Research in the following areas is necessary to determine the origins and architecture of variability and to explain similar or dissimilar responses to diet and food components by subpopulations, as influenced by genetic, epigenetic, and ethnic and/or racial differences.

Omics research, such as nutrigenetics and nutrigenomics (e.g., epigenetics, transcriptomics, proteomics, and metabolomics), will help to determine how specific nutrients interact with genes, proteins, and metabolites to predict an individual’s health. Omics provide information on individualized nutrient requirements, including how nutrients are digested, absorbed, and metabolized, and their functions in the body. Omics will help to determine and reflect an individual’s nutritional status and will aid in the creation of new nutritional and disease biomarkers.

Microbiome.

Diverse microbes, such as bacteria and viruses, live in and on the body and contribute to the microbiome, which is estimated to have 10 times as many cells as the body itself ( 1 ). Microbes can vary in type and quantity, making each organism’s microbiome unique—although subpopulations may have similar microbiome characteristics. The microbiota needs to be better defined, and changes due to diet, age, physiologic state, and disease need to be determined. Research is needed to determine the microbiome’s role in varying biological responses to diet and food components and its importance in disease prevention and progression. Conversely, research is also needed to determine how the microbiome is influenced by diet and other environmental factors.

Biological networks.

Basic research is needed to provide a better understanding of biological networks, such as an individuals’ genome (DNA/RNA protein profiles), and how these networks affect metabolic responses to diet and food. Environmental interactions, including nutrients and other dietary components, bacteria, viruses, and chemical contaminants, all may affect the responsiveness of biological networks to specific foods and the entire diet.

Tissue specificity and temporality.

Research is needed to describe the mechanisms by which dietary factors affect variability in development and functioning, including which tissues are most influenced by dietary factors and when during the most critical stages in life this influence occurs.

2) Understanding the impact of nutrition on healthy growth, development, and reproduction

Epigenetics/imprinting..

Epigenetics and imprinting research examines how exposures to dietary components during critical periods of development may “program” long-term health and well-being. Research is needed to determine how early nutritional events contribute to disease later in life and alter normal developmental progression.

Early nutrition.

Research is necessary to better understand the role of diet and individual food components on normal growth and development. This includes the role of parent’s preconception diets, the maternal diet during pregnancy, and early nutritional events. Studies indicate that the timing of an infant’s introduction to solid foods may increase the likelihood of becoming obese later in life ( 2 ). These findings are important given that the number of overweight children in the United States has increased dramatically in recent years ( 3 ). Research is now needed to determine the best approaches to influence these factors during early life. The important role of nutrition throughout early life on growth and development, as well as on health and well-being, needs to be continually assessed.

Nutrition and reproductive health.

The impact of nutrition on reproductive health, including before and after conception, requires further research. Nutrition has a direct impact on both maternal and paternal fertility and the ability to conceive and also plays a key role in preventing diseases related to reproductive organs, including prostate and ovarian cancers. Although numerous studies have investigated how fruit and vegetable consumption may affect risk of breast, prostate, and other cancers, there is no clear consensus in the scientific literature. Thus, well-designed controlled intervention studies are needed to determine whether effects are limited to subpopulations, what factors influence a response and what mechanisms may account for changes in health.

3) Understanding the role of nutrition in health maintenance

Health maintenance includes noncommunicable disease prevention and treatment as well as weight management. The role that food components, particularly novel ingredients, contribute to health maintenance requires continuing research. Researchers and the public rely on dietary guidance, including the DRIs, to guide nutrition recommendations and health policy. Research is needed to better define the nutrient needs that best support health maintenance in all populations and their subgroups, from infancy throughout life. Nutrition across life is a fundamental issue that requires investigation so that recommendations will “match” with true biological needs.

Optimal bodily function.

Research is needed to determine the roles that nutrition and fitness, both singularly and together, have in maintaining bodily functions, including cognitive, immune, skeletal, muscular, and other functions. Evolving research areas include prevention of disease-related processes, such as inflammation, and definition of mechanisms that have an important role in health maintenance, such as immunocompetence. Animal models are used to understand the requirements for optimal health in humans and production animals.

Energy balance.

Research is also needed to examine the use of a systems approach to achieve energy balance including and integrating environmental, biological, psychosocial, and food system factors. A systems approach is preferable because the standard experimental approach of varying one factor at a time has accomplished little to address the populationwide problem of energy imbalance. A solution-oriented approach that is comprehensive in nature and takes into account the complexities of achieving energy balance must be created. Although far more research is needed to identify systemwide changes that maximize energy balance, intriguing examples exist. “Shape Up Somerville, MA,” effectively reduced weight gain in high-risk children through a multifaceted community-based environmental change campaign ( 4 ). Shape Up Somerville increased the community’s physical activity and healthful eating through physical infrastructure improvements and citywide policy and programming changes.

4) Understanding the role of nutrition in medical management

The rapid translation of nutrition research advances into evidence-based practice and policy is a priority for ensuring optimal patient care and effective disease management. Nutrition researchers have a key role in bridging the gap between disease prevention and disease treatment by fostering clinical research, providing innovative education for caregivers and patients, and delineating best practices for medical nutrition in primary care settings.

Disease progression.

To improve the medical management of disease, research is needed to determine how nutritional factors influence both disease initiation and progression, as well as how nutrition affects a patient’s response to therapy. Genetic and epigenetic variations among individuals can result in both positive and negative responses to diets, to specific foods, and to novel food components. The issue of individual variability is of considerable importance in refining medical management, including nutrition support, and requires continuing research.

Expanded research will allow us to better understand and minimize unfavorable impacts of both reduced and elevated nutrient intakes on disease progression and overall health. Disease/mortality response curves are U-shaped for many nutrients (that is, there is an increased risk of adverse outcomes if the nutrient is ingested in either too low or too high amounts). The importance of achieving a proper nutrient balance is seen in the example of chronic inflammation. Chronic inflammation contributes to many noncommunicable diseases and can result from high intakes of proinflammatory omega-6 fatty acids in the face of low intakes of anti-inflammatory omega-3 fatty acids ( 5 ). Research will help to determine the desired intake for essential and nonessential nutrients alone and when combined with other nutrients in the diet.

Nutrition support for special subgroups.

Nutrition research is needed to establish the required nutritional needs that best support survival, growth, and development in subpopulations, such as in chronically diseased patients, in children, and in aging adults. With the success of medical advances, as have been seen with in vitro fertilization and neonatal care, caring for preterm infants presents a new challenge in early nutritional management. Preterm infants have special nutrition needs that will greatly affect their future growth and development, as well as their eventual health status as adults.

5) Understanding nutrition-related behaviors

Drivers of food choice..

Understanding the link between behavior and food choices can help tackle obesity and other nutrition-related issues that are a public health priority. Individual food choices can be influenced by a number of different drivers including the following:

• Government policy
• Environmental cues
• Cultural differences
• Communication tools, such as social networking and food marketing

Research is needed to identify the impact of these various drivers and understand how they work alone or together to influence nutrition-related behavior. Research will show how these drivers should be altered to have the highest positive influence on individual behavior and therefore public health. For example, the state of Mississippi recorded a 13% decline in obesity among elementary school students from 2005 to 2011 ( 6 ). Multiple changes in the environment occurred, such as the setting of standards for foods sold in school vending machines, setting a requirement for more school exercise time, mandating healthier environments in childcare settings, and establishing programs that encouraged fruit and vegetable consumption. The challenge now is to determine what effect these combined actions will have on obesity-related behaviors in the long run.

Nutrition and brain functioning.

Further explorations of the biochemical and behavioral bases for food choices and intake over time are essential. Brain function as it relates to food desire and choice needs to be clarified through research, and the multiple hormones that affect eating require further study as well. Factors such as meal frequency and size, speed of meal consumption, and how these factors are influenced by social cues require objective data, which can only be provided by research. Understanding how the marketing of healthy behaviors could help consumers achieve dietary guidance goals should be a priority. As part of this approach, innovative and practical methods for accurately measuring and evaluating food purchases and eating occasions must be developed.

Imprinting.

Because of the high propensity of obese children remaining obese as adults ( 7 ), additional research is needed to determine how eating and satiety behaviors are imprinted during critical periods of development and to show how food components affect neural biochemistry and brain functioning—and therefore shape behavior. This research will provide us with a better understanding of how and why an individual makes particular food choices. Although scientists recently validated the concept that food availability during pregnancy has permanent effects on gene expression in children ( 8 ), human studies are needed to confirm or refute the hypothesis that fetal programming, resulting from maternal obesity, leads to excess weight in children and into adulthood.

6) Understanding the food supply/environment

Food environment and food choice..

Simply knowing or understanding what constitutes a healthy diet is not enough to change an individual’s diet or lifestyle. Understanding how the food environment affects dietary and lifestyle choices is necessary before effective policies can be instituted that will change a population’s diet in a meaningful way. Examples of key questions that should be addressed include the following:

• Is current dietary guidance an effective way of communicating dietary change?
• Do food assistance programs promote positive dietary patterns or have negative dietary and health consequences?
• What role does food advertising play in food decision-making among different age groups and educational levels?
• How do farm-to-fork food systems, with an increased emphasis on local agricultural production and consumption, influence dietary patterns and behaviors?
• How can farm-to-fork food systems ultimately be used to promote healthy behaviors and improve public health?
• How can we most effectively measure, monitor, and evaluate dietary change?

Food composition and novel foods and food ingredients.

Having an affordable, available, sustainable, safe, and nutritious food supply is also an important underpinning for making significant changes to a population’s diet and lifestyle. Examples of key research areas to address include the following:

• Enhancing our knowledge of the nutrient and phytonutrient content and bioavailability of foods produced, processed, and consumed
• Studying how to better align and foster collaboration between nutrition and agricultural production
• Can shifting agricultural focus from principally agronomic to include quality factors (such as taste, flavor, and nutritional value) have positive effects on fruit and vegetable consumption?
• Can we leverage technologies, such as biotechnology and nanotechnology, to develop novel foods and food ingredients that will improve health, both domestically and abroad, and provide credible, tangible functional health benefits?

Public/private partnerships.

To tackle these enormous challenges requires the coordinated efforts of public and private partners. The development of public/private partnerships between food and agricultural industries, government, academia, and nongovernmental organizations has the potential to advance nutrition research, enabling meaningful changes to be made to American and global diets (e.g., increased fruit and vegetable consumption to match government recommendations). We need to examine successful examples of public/private partnerships that have resulted in improved nutritional status and food security in specific populations ( 9 ).

Nutrition research is truly a cross-cutting discipline, and the Working Group identified several tools that are also necessary to advance the priority needs in nutrition research. Adequately powered intervention trials continue to be essential for validating research theories arising from experimental and epidemiologic studies. However, the development of new, impactful tools will help us to more effectively quantify dietary intake and food waste and to determine the effectiveness of nutrition standards, such as DRI values and the Dietary Guidelines for Americans . Although not a traditional tool, multidisciplinary partnerships among scientific societies, government, industry, academia, and others are fundamental to advance the nutrition research agenda. ASN and its membership must be proactive not only in efforts to advance nutrition research (including initiating and leading partnerships) but also in developing the tools needed to enhance the field. ASN recognizes the need to facilitate effective communication among academia, industry, government agencies, consumers, and other stakeholders to advance nutrition.

Omics (especially genomics, proteomics, and metabolomics) will enable us to determine how specific nutrients interact with genes, proteins, and metabolites to predict the future health of an individual. A field of study that encompasses technological advances as well as omics-based research, it is sometimes referred to as personalized nutrition. Omics hold the keys to major nutrition breakthroughs in noncommunicable disease and obesity prevention. Omics provide information on how well nutrients are digested, absorbed, metabolized, and used by an individual. Moreover, omics will lead to new biomarkers that reveal a person’s nutritional status and health status all at one time.

2) Bioinformatics

Bioinformatics is an interdisciplinary field that uses computer science and information technology to develop and enhance techniques to make it easier to acquire, store, organize, retrieve, and use biological data. Bioinformatics will enable nutrition researchers to manage, analyze, and understand nutrition data and to make connections between diet and health that were not previously possible. Databases are necessary to gain the full benefits of bioinformatics, because they make nutrition data easily accessible in a machine-readable format.

3) Databases

Accurate, up-to-date food and nutrient databases are essential to track and observe trends related to the nutrition and health of individuals. Databases link food and supplement composition and intake data to health outcomes. Nutrient databases should be expanded to cover more foods and their bioactive components, including nonessential nutrients. Nutrition data must be incorporated into databases related to novel research areas, such as nutrigenomics and the microbiome, to adequately link these areas with nutrition. Data collection must also be improved with enhancements such as photographic food intake documentation, direct upload of food composition and sensory characteristics (if not proprietary) from food manufacturers, and biological sample collection.

4) Biomarkers

Intake, effect, and exposure biomarkers allow us to determine and monitor the health and nutritional status of individuals and subpopulations, including ethnic and racial minorities. Biomarkers that are responsive to diet and nutrition will help assess disease progression and variability in response to treatment, while improving early diagnosis and prevention. Biomarkers must continue to be developed and validated to accurately track food and nutrient intake given our rapidly changing food supply.

5) Cost-effectiveness analysis

Cost-effectiveness analysis is a tool used to calculate and compare the relative costs and benefits of nutrition research interventions. Cost effectiveness analysis helps to determine the most cost-effective option that will have the greatest benefit to public health.

CONCLUSIONS

The multidisciplinary nature of nutrition research requires collaboration among research scientists with differing areas of expertise, many different stakeholders, and multifaceted approaches to develop the knowledge base required for establishing the evidence-based nutrition guidance and policies that will lead to better health and well-being of world populations. Proper nutrition offers one of the most effective and least costly ways to decrease the burden of chronic and noncommunicable diseases and their risk factors, including obesity. Although there is skepticism about the ability to complete large, well-controlled dietary interventions at a reasonable cost in the United States, the success of the Lyon Diet Heart study in France ( 10 , 11 ) and the PREvención con DIeta MEDiterránea (PREDIMED) study in Spain ( 12 ), both of which used variations of the Mediterranean diet, show this approach can be successful, even in the presence of drug treatment of cardiovascular risks in the latter study. Both of these studies showed significant reductions in cardiovascular disease (and cancer in the Lyon study) after relatively modest dietary changes.

Perhaps the greatest barrier to advancing the connections between food and health is the variability in individual responses to diet; it is also the origin of public skepticism to acceptance of dietary advice and the opportunity for entrepreneurship in the private sector. Imagine being able to identify, with certainty, those most likely to benefit from prescriptive nutrition advice through the various omic technologies and then providing these groups of people with customized nutrition advice based on their metabolic risk profiles. This is the new frontier of the nutritional sciences that offers the opportunity to predictably engineer our physiologic networks for health through diet. The confidence this approach would bring to the skeptical consumer would improve adherence to weight management and disease treatment techniques and improve the chances of success for disease prevention. To realize the full positive impact of achieving good nutrition on disease prevention and the health of populations, we must have the will to invest in and support the 6 key areas of nutrition research that have been outlined above.

Advanced cell atlas opens new doors in biomedical research

Researchers at Karolinska Institutet have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease. The study is published in Genome Biology.

Simultaneous measurement of numerous biomolecular variables, known as multi-omics, enables deep and comprehensive profiling of human biology. The new Single Cell Atlas (SCA) is based on analyses of thousands of human tissue samples from 125 different adult and fetal tissues. The researchers combined eight cutting-edge omics technologies, including single-cell RNA sequencing, whole-genome sequencing, and spatial transcriptomics to map and localise genes expressed in the tissue.

The platform provides unique insights into individual cell properties and their interactions within tissues. The extensive collection of data is freely accessible through the platform's website.

"The Single Cell Atlas not only saves time and resources but also fosters a collaborative environment for scientists from diverse fields, paving the way for new discoveries and innovations," says the study's first author Lu Pan, researcher at the Institute of Environmental Medicine, Karolinska Institutet, Sweden.

Looking ahead, the team plans to refine the SCA by introducing more detailed analyses and annual updates. These enhancements will fill gaps in tissue representation and expand the sample size, allowing for more precise research.

"The creation of the SCA marks a significant step forward in biomedical research," says the study's last author Xuexin Li, researcher at the Department of Physiology and Pharmacology (previously at the Department of Medical Biochemistry and Biophysics), Karolinska Institutet. "Our goal is to continually enrich the atlas, making it an invaluable resource for understanding human health and disease."

The research was done in collaboration with China Medical University and several other international collaboration partners in The Single Cell Atlas Consortium. The study was financed by Karolinska Institutet and the KI Network Medicine Global Alliance (KI NMA). Coauthor Volker Lauschke is CEO and shareholder of HepaPredict AB, co-founder and shareholder of PersoMedix AB, and discloses consultancy work for Enginzyme AB. The other authors declare that they have no competing interests.
