Study questions benefits of fish oil after mild brain injuries

A first-of-its-kind study led by the Medical University of South Carolina raises questions about the value of fish oil supplements for people with repetitive mild traumatic brain injuries.

Early genetic signals connect diabetes subgroups to heart disease risk

A growing body of research shows that diabetes can be stratified into five different subgroups. Researchers at Lund University have now investigated whether a person's genetic predisposition to different diabetes subgroups can help assess the risk of developing coronary artery disease.

WSU researchers use spice extracts to enhance medical bone implants

An extract of turmeric and ginger helps bone implants bond strongly while killing bacteria and cancer cells, according to new research from Washington State University with implications for millions of patients with joint replacements and bone cancer.

Analysis reveals long-term male bias in European meat access

Access to nutritious food is a fundamental pillar of human success, but such access has been unequal throughout history. In pre-industrial European societies, meat was a highly sought-after food, and access to it was often related to a higher social status.

New obesity definition could delay treatment and widen health gaps

The Lancet obesity framework aims to improve risk assessment but risks delaying treatment and deepening health inequities, according to recent evaluations.

Could vitamin D in midlife protect your brain from early Alzheimer’s?

Higher serum vitamin D in midlife is associated with reduced tau burden in the brain, highlighting its potential role in early dementia risk assessment.

Challenging processed meat risks for dry-cured ham consumption

The effects of dry-cured ham on cardiometabolic health are nuanced, with evidence suggesting it may not adversely affect key health markers in moderation.

How gut microbes may shape heart attack damage and recovery

This review argues that gut microbes and the metabolites they produce, especially SCFAs and TMAO, may shape how the heart responds to myocardial infarction through epigenetic pathways such as DNA methylation, histone modification, and non-coding RNAs. It also outlines potential intervention routes, including diet, probiotics, postbiotics, and metabolite-targeted therapies, while noting that much of the evidence remains translational and not yet clinically definitive.

Large-scale exposome research shows how multiple factors influence disease risk

For decades, scientists have been carefully unraveling the role of genes in disease by examining how small variations in a person's genetic code can shape lifelong risk of developing common conditions such as cancer, diabetes, or heart disease.

Princeton researchers reveal new links between high-fat diets and aggressive breast cancer

Princeton researchers have revealed new links between high-fat diets and aggressive breast cancer, demonstrating the important role fat plays in making some cancers more invasive.

Study shows how environmental factors accelerate biological age of the brain

The latest findings from the Global Brain Health Institute (GBHI) at Trinity College Dublin identify important brain health implications for prevention, public health, and policy.

Pediatric experts say plain yogurt is safe from 6 months and belongs in a baby’s diet

An expert panel review says plain, whole yogurt with no added sugar or sweeteners can be introduced from 6 months as part of complementary feeding, provided it does not replace breast milk or infant formula as the main source of nutrition. It also explains that yogurt provides live microorganisms and key nutrients, is generally well tolerated, and helps address common myths about inflammation, mucus, acne, sugar, and safety.

Salt-adding behavior varies by gender and lifestyle factors

Salt has been used as seasoning and food preservative for thousands of years, but having too much of it can lead to various diseases, including high blood pressure, cardiovascular diseases, and kidney disease.

Oral molecule prevents kidney stones and restores survival in mice

Scientists at the Buck Institute for Research on Aging have shown that an orally administered small molecule, N-propargylglycine (N-PPG), can completely prevent the formation of calcium oxalate kidney stones, protect against kidney failure, and fully restore normal survival in a mouse model of Primary Hyperoxaluria Type 2 (PH2), a rare and currently untreatable genetic disorder that causes progressive kidney failure in infants and young adults.

Moderate wine intake tied to slower biological aging in men

Researchers studying 22,495 adults in Southern Italy found that men with moderate wine intake in the traditional Mediterranean diet range showed slightly slower biomarker-based biological aging, with the lowest estimated aging signal at about 170 mL per day. The study also found that overall ethanol intake did not show the same moderate-level pattern, and higher total alcohol intake was linked to faster biological aging in dose-response analyses.

Researchers find 25 ways to rate meals and diets for both health and environmental impact

This systematic review identified 25 food-based indices, termed NECIs, that combine nutritional value and environmental impact to classify or rank meals and diets. It found wide methodological variation across 27 approaches, suggesting a need for more harmonized tools to support healthier and more sustainable food choices.

Obesity, sleep, smoking, and inactivity show the strongest links to hypertension in U.S. adults

A cross-sectional analysis of 20,912 U.S. adults found that obesity, overweight, inadequate physical activity, smoking, and short or long sleep were each associated with higher odds of hypertension, while overall diet quality by HEI-2015 was not significantly associated. Sleep associations differed by sex, and lower sodium intake remained linked to lower odds of hypertension in sensitivity analyses.
