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

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

CT scans linked vitamin D levels to fat within muscles after bariatric surgery

Researchers followed 113 adults for one year after bariatric surgery and found that those with higher postoperative vitamin D concentrations had less fat infiltration within certain muscles and lower visceral adiposity. They found no significant association between increases in vitamin D and changes in body composition after correction for multiple comparisons, while preoperative vitamin D levels did not independently predict postoperative body composition.

Amyloid fibers help sperm deliver RNA to mouse embryos

Researchers identified RNA-associated amyloid fibrils in human seminal fluid and demonstrated that synthetic PAP fibrils could enter mammalian sperm. In mouse IVF experiments, these fibrils helped sperm deliver RNA to embryos, where the detected reporter-protein signal was at least tenfold higher than without fibril exposure.

Semaglutide changes gut bacteria in rats beyond what eating less explains

Researchers compared semaglutide-treated male and female rats with pair-fed animals receiving the same amount and type of food to distinguish drug-associated microbiome changes from those linked to reduced eating. Semaglutide altered bacterial richness and community composition, with some changes absent from the pair-fed groups and uncertain consequences for health.

Beer and liquor show more oral bacteria links than wine in a large US study

Researchers analyzed beverage intake and oral microbiome data from 5,598 adults across three US cohorts and found that alcohol consumption showed the strongest associations with oral bacterial diversity and composition among the beverages examined. Higher alcohol intake was associated with greater bacterial richness and differences in genera linked to oral health, but the cross-sectional preprint could not establish whether alcohol caused these differences or influenced disease risk.

Can happy feelings trigger eating too? Researchers explored both sides of emotional eating

Among 3,834 members of weight-management programs, greater recent weight loss was associated with less emotional eating, fewer food cravings, and better mood. Participants identified distraction, meal planning, healthier food swaps, and group support as helpful strategies, but the observational study could not establish whether these approaches caused weight loss.

Beer, wine or spirits: A large study finds different mortality patterns for each

Researchers analyzed data from 340,924 UK Biobank participants and found that high total alcohol consumption was associated with greater all-cause, cardiovascular, and cancer mortality, while moderate consumption was linked to increased cancer mortality. Beer/cider and spirits showed associations with higher mortality across several outcomes, whereas low-to-moderate wine consumption was linked to lower mortality for certain outcomes, though the observational study cannot establish causation.
