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.

Moderate coffee intake may lower heart failure risk

A systematic review and dose-response meta-analysis of seven prospective cohorts found that drinking 2 to 4 cups of coffee a day was associated with a modestly lower risk of incident heart failure. The lowest estimated risk appeared at 1 to 2 cups daily, although the evidence for a true non-linear J-shaped pattern was suggestive rather than definitive.

Wholegrain rye changes gut bacteria and lowers inflammation in obesity trial

In a 12-week randomized trial, replacing refined wheat with wholegrain rye in a calorie-restricted diet did not produce greater weight loss in adults with overweight or obesity. Wholegrain rye did, however, lower C-reactive protein and alter gut microbiota and short-chain fatty acids in ways that may have positive cardiometabolic implications.

Palmatine improved fatty liver markers in a preclinical type 2 diabetes study

Researchers used a bioinformatics-plus-rat-model approach to investigate how palmatine may help treat T2DM-associated MASLD, identifying five core targets: ADRB2, BCL3, EGR1, FOS, and MAP3K8. In rats, palmatine improved liver injury, inflammation, oxidative stress, glycolipid metabolism, steatosis, and fibrosis, while reducing apoptosis-related signaling, providing a preclinical foundation for further therapeutic study.

Leaving home may worsen diet quality in young adults, Australian study finds

Australian longitudinal data suggest that leaving the parental home is associated with a small decline in overall diet quality and a short-term rise in discretionary food intake during the transition from adolescence to adulthood. The study also found that diet quality tended to worsen most among those moving in with a partner, while the discretionary-food gap narrowed over time.

Replacing sedentary time improves insulin resistance in adolescents

Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Higher meat intake may slow cognitive decline in older adults with APOE ε4

In older Swedish adults, higher meat intake was associated with slower cognitive decline and lower dementia risk among people carrying APOE ε3/ε4 or ε4/ε4, but not among other genotype groups. A higher processed-to-total meat ratio was linked to worse dementia outcomes, while unprocessed red meat and poultry showed no substantial difference.

U.S. study links ultra-processed foods to lower odds of fertility

A cross-sectional NHANES study of 2,582 U.S. women found that higher ultra-processed food intake was associated with lower odds of being classified as fertile based on self-reported infertility history. Greater Mediterranean diet adherence was linked to higher odds of fertility in adjusted models, but that association was no longer significant after accounting for obesity.
