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.

Campus dining halls fail to provide appealing protein choices for college students

A new University of Maine study has identified what researchers describe as a campus protein challenge. Although students generally consumed adequate amounts of protein, many reported that campus dining halls failed to provide protein choices they considered flavorful, appealing or prepared in ways they viewed as healthful.

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.

Cardiovascular disease surpasses cancer as top killer of Hispanic populations in the U.S.

Cardiovascular disease has surpassed cancer as the leading cause of death among Hispanic adults in the U.S., driven by rising rates of obesity, diabetes, high blood pressure and other risk factors that often begin earlier in life for Hispanic people.

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. UPF intake showed no consistent relationship with growth through 12 months, while dietary diversity was not reduced among infants consuming more UPFs.

An 8-hour eating window stood out for weight loss, but the full picture is more complicated

A pooled analysis of individual data from five time-restricted eating trials involving 124 adults linked shorter eating windows with modestly greater weight loss. Eight-hour TRE was associated with greater weight loss than 12-hour TRE and controls, while cardiometabolic outcomes showed no consistent relationship with eating-window duration and several weight associations weakened after adjustment.

Cockroaches have a reputation for surviving almost anything, but this diet proved deadly

A laboratory study tested how ultra-processed, unprocessed, and mixed diets affected survival in 127 lobster cockroaches, Nauphoeta cinerea. Cockroaches fed only ultra-processed foods had higher mortality than those given unprocessed or mixed diets, although the study could not determine whether processing, ingredients, nutrition, or differences in food intake caused the effect.

Early studies hint that ketones may affect pathways linked to PTSD

An integrative review found that ketogenic therapy may influence metabolic, inflammatory, oxidative stress, and neurotransmitter pathways implicated in PTSD, with animal studies and small human studies reporting early signs of symptom improvement. Human evidence remains limited to very small cohorts, case reports, and pilot studies, and controlled trials have yet to establish clinical efficacy.

Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.

Healthy checkout ordinance linked to lower soda and candy sales

A new study found that a healthy checkout ordinance implemented in Berkeley, Calif. supermarkets, drug stores, and mass-market retailers in 2021 was linked to notable decreases in soda sales overall and small-package candy in supermarkets, but greater enforcement of such policies is essential for sustained and meaningful public health benefit.

Refined starch activates immune pathways after low-carb weight loss

After substantial weight loss on a very-low-carbohydrate diet, participants who switched to a diet rich in refined starch showed greater activation of circulating immune and metabolic pathways than those who continued the low-carbohydrate diet or consumed a high-carbohydrate diet rich in added sugar. Mouse experiments suggested that activation of the complement immune pathway may help explain the inflammatory response associated with starch intake.
