The Flexitarian Diet: A Flexible Path to Better Health

The flexitarian diet offers a flexible, plant-forward approach that reduces meat intake without full elimination, improving heart health, metabolic outcomes, and environmental sustainability. Evidence links it to lower cholesterol, better weight control, reduced cancer risk, and improved nutrient sufficiency compared to strict vegan diets.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Fruit fly gut cells track hunger using internal cell viscosity

Researchers led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered that the natural turnover of gut cells in the fruit fly depends on how much food the flies get, rather than any specific nutrient.

Low-fat vegan diet helps people lose weight without cutting back on food

A low-fat vegan diet lowers the energy density of the foods people eat by roughly 30%, allowing them to eat satisfying amounts of food while taking in fewer calories and losing weight-without deliberately restricting calories-according to new research published in JAMA Network Open.

New research highlights carbohydrate role in early human brain development

Fruit, honey and other naturally sweet foods may have helped fuel the evolution of the human brain, according to new research from the University of Sydney and the University of Glasgow.

Genetic analysis of 1 million people points to FNIP1 as a promising metabolic target

Mega-scale exome sequencing of 1,032,116 people identified 59 independent genes linked to the TG:HDL ratio, including 44 rare-coding associations not detected in the previous largest analysis. Ultra-rare FNIP1 loss-of-function variants were associated with favorable fat distribution, lower liver fat and glycemia, and around 60% lower odds of a composite cardiometabolic disease outcome.

D-serine promotes gastric cancer growth by suppressing tumor immunity

Researchers from Keio University have found that D-serine increases the growth of gastric cancer by creating an immunosuppressive and anti-inflammatory tumor microenvironment.

Nighttime light linked to conflicting signs of biological aging

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.

Swiss flagship project harnesses AI and sensors for diabetes prevention

Type 2 diabetes generates high healthcare costs in Switzerland and causes significant suffering for those affected.

First-trimester protein intake linked to lower odds of small-for-gestational-age birth

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

Mouse study shows how liraglutide briefly rewires gut bacterial communities

Researchers treated male high-fat-fed mice with liraglutide for 14 days, then tracked fecal bacterial communities after a 7-day washout using 16S rRNA sequencing. Liraglutide shifted the microbiome toward Lactobacillus- and Leptogranulimonas-related taxa while reducing several fermentative taxa, but most changes moved back toward baseline after treatment stopped.

Better sleep may boost academic and social success in adolescents

A new UC Davis Health study published in Psychological Medicine suggests that when it comes to helping adolescents succeed in school and maintain healthy friendships, sleep may matter more than screen time, exercise or diet.

Exercise helps protect Hispanic adults from late life cognitive decline

Previous studies have examined the associations between adherence to LS7 and cognitive outcomes, with findings suggesting that higher LS7 scores are associated with better cognitive performance, reduced dementia risk and improved brain health.

Researchers suggest a potential therapeutic strategy for muscle loss associated with obesity

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

Blood filtration method helps clear circulating lipids and toxic microplastics

The machine is not new. Some version of it has run in hospital treatment rooms for about four decades, drawing blood from one arm, separating out the plasma, passing it across a filter or an adsorber, and returning it to the other arm.

Daily social connections may improve long-term health and cognition

Calling a friend after a long day. Showing up to a neighbor's dinner when you'd rather stay home. Lingering a little longer in a conversation that didn't need to last.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.

Texas A&M study links polyethylene microplastics to fatty liver disease

Microplastics have become nearly impossible to avoid. They have been detected in oceans, drinking water and even the human body, but scientists are still uncovering how they affect human health.

Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.
