Aging population drives rise in smoking-related mortality risks

Smoking kills. But why does smoking seem more likely to kill now than a few decades ago? In 1987, a smoker had a 3.4% chance of dying within five years. By 2013, a smoker had a 4.9% chance of drying within five years.

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.

New roadmap integrates arts into global health and wellbeing

Researchers have developed a roadmap for integrating the arts across health and wellbeing systems globally, from population health and prevention to community pathways and clinical care.

Experimental RNA therapy enhances weight loss while preserving lean muscle

GLP-1 drugs have revolutionized obesity treatment, but they can lead people to lose muscle mass along with fat. And when patients stop treatment, they often regain their weight - primarily as fat.

Maldives meets UN target for reducing premature chronic disease deaths

The Maldives has become the only country in the World Health Organization's South East Asia region to meet the UN target for reducing premature deaths from non-communicable diseases (NCDs), such as cardiovascular and chronic respiratory diseases, cancers and diabetes.

Early life sugar exposure linked to higher adult anxiety risk

Exposure to sugar in the first 1,000 days of a child's life increases the risk of developing anxiety in adulthood, a new study from the University of Surrey reports.

Stalled gut microbiome development triples risk for type 1 diabetes in children

Type 1 diabetes affects more than 9 million people worldwide, including 1.8 million children and adolescents.

Sugary drinks stood out in this stomach cancer study, but diet drinks did not

In two large US prospective cohorts, consuming more than one sugar-sweetened beverage a day was associated with higher gastric cancer incidence compared with consuming less than one serving a month. Artificially sweetened beverages were not associated with gastric cancer incidence, and the authors called for further studies to confirm the findings and clarify possible biological mechanisms.

Older adults with higher polyphenol intake were less likely to have mild cognitive impairment

In a cross-sectional study of 92 older Italian memory-clinic patients, higher habitual intake of total dietary (poly)phenols and several specific subclasses was associated with a lower likelihood of mild cognitive impairment (MCI). Total (poly)phenol intake was not associated with cognitive test performance or circulating inflammatory biomarkers, and the authors cautioned that the small observational study cannot establish causality.

Scientists discover metabolite fueling aggressive brain tumor growth

Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from scientists at Children’s Medical Center Research Institute at UT Southwestern (CRI) published in Cell.

Being active may not tell the whole story when it comes to weight gain

A five-year study of 2,606 young and early-midlife Finnish municipal employees examined how leisure-time physical activity and sedentary behavior were associated with gaining at least 10% of baseline body weight. About 24% of women and 12% of men experienced major weight gain, with the analysis pointing to the importance of considering activity and sedentary time together.

Can maternal diet prevent infant food allergy? A large trial puts eggs and peanuts to the test

A large Australian randomized trial of 2,137 pregnant women tested whether substantially increasing egg and peanut consumption during pregnancy and breastfeeding could prevent food allergy in infants with a strong family history of allergic disease. Higher maternal intake did not significantly reduce IgE-mediated egg or peanut allergy at 1 year, although the lower-than-expected allergy rate limited statistical power and the results could not exclude a clinically important benefit.

New indicators could accelerate development of anti-aging drugs

Twelve candidate indicators, based on studies in mice, could make developing anti-aging interventions faster-while offering new insights into age-related diseases.

Time-restricted eating may slow early-stage Huntington's disease

A simple change in when people eat may offer a promising new approach for Huntington's disease, according to research led by Oregon Health & Science University.

Study identifies bile acid that helps reduce excess fat accumulation in the liver

Non-alcoholic fatty liver disease (NAFLD), now known as metabolic dysfunction-associated steatotic liver disease (MASLD), is a common condition that causes excess fat to build up in the liver, affecting about one-quarter of adults worldwide.

Fermented dairy was linked to lower mortality, but the pattern shifted at higher intakes

Analysis of 37,366 US adults found that fermented dairy consumption was associated with lower all-cause and cardiovascular mortality, with consumers showing adjusted hazards 18% and 20% lower, respectively, than non-consumers. Dose-response analyses indicated that the inverse association was concentrated at intakes below about 150 grams per day, while the observational study could not establish causality.

Scientists tested how much whole grain makes a difference. The answer was not simply “more”

A meta-analysis of 87 randomized trials found that increasing whole-grain intake was associated with improvements in several cardiometabolic risk factors, although many individual changes were small or clinically unimportant. Dose-response analyses suggested that the magnitude of the effects varied by outcome and intake level, with limited evidence at very high intakes.

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.

Eating four to six wholegrain servings daily protects heart health

Eating four to six servings of wholegrain each day reduces several major risk factors for cardiovascular disease, according to a new study published in the European Heart Journal today (Wednesday).
