Students in a new study were neither clearly positive nor negative about more climate-friendly school meals.

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.

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.

Women with type 2 diabetes saw striking changes after 24 weeks of this eating pattern

A 24-week randomized trial found that a lacto-vegetarian diet combined with 14-hour time-restricted eating improved glycemic control, insulin resistance, body weight, and lipid measures in Indian women with type 2 diabetes. The combined, nutritionist-supported intervention was generally well tolerated, but its individual dietary and fasting effects cannot be separated and longer-term studies are needed.

What a 38-year study suggests about red meat, white meat, and mortality

Lower intake of red and processed meat was associated with small reductions in all-cause, heart disease, cancer, and stroke mortality in a cohort of nearly one million US adults followed for decades. White-meat-only diets showed additional benefits in some subgroups, while vegetarian diets produced few consistent associations and were limited by small participant numbers and a single baseline dietary assessment.

Whole grains, legumes and vegetables stand out in a major review of diabetes diets

Healthy plant-based diets rich in whole grains, legumes, fruits, vegetables, nuts, and seeds are associated with better glycemic control and a lower risk of type 2 diabetes. The review finds that food quality and processing matter more than simply avoiding animal foods, while unhealthy plant-based patterns and higher red and processed meat intake are associated with greater metabolic risk.

Meat, stress and risk-taking: what 38 experiments reveal about masculinity threat

Experimental evidence suggests that masculinity threat can push some men toward health-risk behaviors, with the clearest and most consistent effects seen in meat-related food choices. Across 38 experiments, effects on stress, fitness, risk-taking, and relationships were mixed or limited, while individual beliefs about masculinity shaped how men responded.

Dutch study shows why plant-based eating can miss key nutrients

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.

Plant-based diets offer heart benefits but may require supplements

A study reveals unsupplemented vegan diets in Northeast China lead to micronutrient deficiencies, despite benefits for body composition and cholesterol levels.

USC study links modified Mediterranean diet to longer lifespan

A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published today in the journal Cell Metabolism.

Yoga and meditation show promise for gut health

This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.

Four-week diet intervention shifts biological aging markers

A short-term shift to whole-food, plant-based diets alters aging biomarkers in older adults, suggesting rapid physiological adaptation rather than age reversal.

Research links specific diets to reduced biological age

Older Australians who reduce either dietary fat or animal-based protein show signs of reduced biological age, new research from the University of Sydney shows.

Study debunks steroid myths, framing creatine as an essential energy-providing molecule

Creatine, a compound often associated with gym-goers and athletes, has long been touted as a performance-enhancing supplement. But beyond the hype, what does science actually reveal about its effects on the body and mind?

High-quality plant-based diets linked to lower dementia risk

Eating a higher quality plant-based diet is associated with a lower risk of Alzheimer's disease and other related dementias compared to eating a lower quality plant-based diet, according to a study published April 8, 2026, in Neurology, the medical journal of the American Academy of Neurology.
