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.

What links smoking, body fat, mental health, genes, and heart risk? Inflammation may be part of the answer

In a large UK Biobank study, higher levels of the chronic inflammation marker GlycA were associated with smaller heart chambers, thicker heart walls, impaired diastolic function, reduced stroke volume, and a 43% higher risk of major adverse cardiovascular events in the highest versus lowest GlycA group. Genetic susceptibility also modified the associations between environmental exposures, inflammation, and cardiovascular risk, while inflammatory proteins in the IL-1, TNF, and IL-6 pathways statistically mediated several of these associations.

Children who ate healthier plant foods had slightly lower blood pressure later

Researchers followed 3,990 Dutch children for an average of 1.6 years and found that higher healthful plant-based diet scores were associated with modestly lower blood pressure and total cholesterol. Children with higher unhealthful plant-based diet scores had lower estimated food costs and distinct metabolite profiles, while healthful scores showed no clear cost association.

Several cups of coffee a day showed no clear diabetes link over 10 years

Researchers followed 1,158 adults in Italy for 10 years, comparing those who drank at least two to three cups of coffee daily with those who drank none. They found no statistically significant difference in new cases of impaired fasting glucose or type 2 diabetes, but the small non-consumer group limits how confidently the study can rule out a difference in risk.

Sugary drinks stood out in this stomach cancer study, but diet drinks did not

In two large US prospective cohorts, consuming more than one sugar-sweetened beverage a day was associated with higher gastric cancer incidence compared with consuming less than one serving a month. Artificially sweetened beverages were not associated with gastric cancer incidence, and the authors called for further studies to confirm the findings and clarify possible biological mechanisms.

Older adults with higher polyphenol intake were less likely to have mild cognitive impairment

In a cross-sectional study of 92 older Italian memory-clinic patients, higher habitual intake of total dietary (poly)phenols and several specific subclasses was associated with a lower likelihood of mild cognitive impairment (MCI). Total (poly)phenol intake was not associated with cognitive test performance or circulating inflammatory biomarkers, and the authors cautioned that the small observational study cannot establish causality.
