Small, combined improvements to sleep, diet and physical activity may yield major heart benefits

New research shows that small improvements to sleep, diet quality, and physical activity, made in combination, are associated with a significantly reduced risk of major cardiovascular events such as stroke, heart attacks, and heart failure.

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.

Firmer potatoes lower post-meal blood sugar spikes

Minimally cooked potatoes may reduce blood sugar spikes, but benefits are short-lived and specific to certain populations, as shown in recent research.

Oral semaglutide fails to slow early Alzheimer’s decline in two phase 3 trials

Two large phase 3 trials found that oral semaglutide 14 mg did not slow cognitive or functional decline over 104 weeks in people with early symptomatic, amyloid-positive Alzheimer’s disease. Semaglutide was generally consistent with its known safety profile and showed some biomarker changes, but these did not translate into clinical benefit.

Do artificial sweeteners increase appetite or food intake?

The study evaluates artificial sweeteners' role in appetite regulation, showing no significant effects on hunger or energy intake during weight management.

Python blood compound could lead to new weight loss therapies

University of Colorado Boulder researchers have discovered an appetite-suppressing compound in python blood that helps the snakes consume enormous meals and go months without eating yet remain metabolically healthy.

Weight-loss drugs linked to preterm birth risk in women with pre-existing diabetes

Weight loss drugs have been linked to an increased risk of premature births among women who took them inadvertently just before or during early pregnancy to treat pre-existing diabetes.

Why do some people respond better to GLP-1 drugs? Gut microbiome may hold clues

A review in the Canadian Journal of Physiology and Pharmacology examines emerging evidence linking glucagon-like peptide-1 receptor agonists (GLP-1 RAs), the gut microbiome, and obesity treatment outcomes. The authors conclude that microbiome changes seen during therapy are most likely driven by diet, behavior, and weight loss, although microbial profiling may eventually help predict patient responses.

New aeroponic technology delivers essential Vitamin B12 through salad crops

A pioneering research-industry partnership has used advances in indoor farming technology to grow pea shoots fortified with Vitamin B12, opening an exciting route to market for farmers and addressing a major public health need.

Study identifies immune cells and RANK protein as fertility regulators

The kick off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then releases other hormones to start gonad –ovaries or testicles –maturation.

Can eating almonds reduce inflammation in obesity?

Adding almonds to the diet of adults with obesity enhances inflammatory cytokine profiles and diet quality, highlighting a simple anti-inflammatory strategy.

Hormone asprosin linked to long-term weight changes after menopause

Researchers at the University of California, Irvine Joe C. Wen School of Population & Public Health have identified how the hormone asprosin influences long-term weight change among postmenopausal women in the United States.

Postbiotics may help treat PCOS by restoring microbiome balance

Emerging studies suggest postbiotics could aid PCOS management by restoring gut microbiome balance and enhancing insulin sensitivity and hormonal regulation.

Specific gut bacteria may signal long-term risk of heart and metabolic disease

Researchers analyzed gut microbiome profiles from 4,792 adults in the HELIUS cohort and tracked cardiometabolic outcomes over time to determine whether specific microbes predict disease risk. Certain microbes were linked to higher or lower cardiovascular risk, while plant-derived microbial metabolites suggested potential diet–microbiome interactions influencing heart health.

Alcohol intake linked to lower micronutrient intake in men with type 2 diabetes

Researchers analyzed 1,565 Japanese outpatients with type 2 diabetes and found that higher alcohol consumption was associated with lower intake of several micronutrients, particularly potassium, calcium, and vitamins A and C, in younger men. The study also linked alcohol intake to a savory dietary pattern rich in rice, meat, fish, and seasonings, highlighting age- and sex-specific nutritional risks.

Ketone body can strengthen the fitness and antitumor activity of CAR T cells

A naturally occurring byproduct of liver metabolism–the ketone body, β-hydroxybutyrate (BHB)–can strengthen the fitness and antitumor activity of CAR T cells.

Engineered lettuce may turn injectable GLP-1 therapies into oral pills

Few drugs have entered mainstream awareness as quickly or as dramatically as glucagon-like peptide-1, or GLP-1 receptor agonists. Initially approved by the FDA for the treatment of type 2 diabetes, they have since also transformed the therapeutic landscape of obesity and weight management.
