Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Traditional Inuit Diet: Foods, Nutrition, and Health Effects

Traditional Inuit diets combine nutrient-dense marine and terrestrial country foods that remain important sources of protein, vitamin D, vitamin B12, iron, and other essential nutrients. The transition toward market foods is occurring alongside changes in cardiometabolic health, micronutrient intake, and gut microbiome patterns, while food insecurity, socioeconomic conditions, physical activity, colonial processes, and environmental change complicate the relationship between diet and health.

Experts call for eating-disorder screening before GLP-1 treatment

An international multidisciplinary panel developed consensus-based recommendations for GLP-1 receptor agonist use in people with eating disorders, calling for screening, individualized monitoring, patient education, and further research into safety and potential therapeutic effects. The experts cautioned that current evidence remains limited and inconsistent, particularly outside binge eating disorder, and identified major gaps in understanding the risk of new or recurrent eating disorders during treatment.

Shatavari may affect more than hormones, and the gut could help explain why

A review in Nutrients examined how bioactive compounds in Asparagus racemosus (Shatavari) may influence cognitive health through the microbiota-gut-brain axis, estrogen-related signaling, neuroinflammation, oxidative stress, and neurotransmitter regulation. Evidence from computational, cellular, animal, and limited human studies suggests several plausible biological pathways, but key questions remain about bioavailability, brain exposure, dosing, and clinical efficacy.

Fermented dairy was linked to lower mortality, but the pattern shifted at higher intakes

Analysis of 37,366 US adults found that fermented dairy consumption was associated with lower all-cause and cardiovascular mortality, with consumers showing adjusted hazards 18% and 20% lower, respectively, than non-consumers. Dose-response analyses indicated that the inverse association was concentrated at intakes below about 150 grams per day, while the observational study could not establish causality.

Scientists tested how much whole grain makes a difference. The answer was not simply “more”

A meta-analysis of 87 randomized trials found that increasing whole-grain intake was associated with improvements in several cardiometabolic risk factors, although many individual changes were small or clinically unimportant. Dose-response analyses suggested that the magnitude of the effects varied by outcome and intake level, with limited evidence at very high intakes.

Finnish adults eat too little of some foods and too much of others, study finds

Analysis of dietary data from 1,655 Finnish adults found that usual food intake often differed substantially from the quantitative targets later set by the Nordic Nutrition Recommendations 2023. Plant-based foods were generally underconsumed, while red and processed meat and dairy intake frequently exceeded study targets, with adherence varying by sex, education, physical activity, age, and energy intake.

Why frailty and heart health may be more closely connected than we thought

A narrative review proposes cardiovascular frailty as a distinct phenotype that brings together blood pressure regulation, vascular aging, oxi-inflammaging, and clinical frailty deficits. The authors argue that a validated cardiovascular frailty index could support earlier detection and personalized care, although longitudinal studies are needed before the concept can be used clinically.

What children eat may leave a measurable signature in their blood

Researchers analyzed 236 blood metabolites in 421 children to examine metabolic signatures associated with three dietary patterns characterized by core foods, animal protein sources, or poor-quality fats and sugars. The results identified distinct, biologically plausible metabolite patterns across dietary exposures, although most individual associations did not survive multiple-testing correction and require validation in independent cohorts.

A study of more than 21,000 adults found an unusual link between psilocybin and diet

Using data from more than 21,800 adults in two UK birth cohorts, researchers found that lifetime psilocybin and LSD use was associated with stronger pro-environmental attitudes and a greater likelihood of following a vegetarian diet, with psilocybin showing the clearer dietary pattern. Mediation analyses suggested that environmental attitudes statistically accounted for the psilocybin-vegetarianism association and part of the association with lower red meat consumption, but the observational design cannot establish causation.

Ultra-processed foods enter babies’ diets early. What comes with them?

In a Denver cohort of 114 healthy infants, higher ultra-processed food intake during complementary feeding was associated with greater added sugar and sodium intake at 9 and 12 months.
