Blueberries reduced blood vessel inflammation in mice, but only with gut microbes present

A preclinical study found that gut microbes help convert blueberry phytochemicals into circulating metabolites, including hippuric acid, that are associated with reduced vascular inflammation. In mice fed a high-fat diet, blueberry supplementation reduced inflammatory markers and monocyte adhesion to blood vessels, but these benefits disappeared following antibiotic-mediated gut microbial depletion.

FSU neuroscientist wins grant to study temperature's impact on salt taste

A Florida State University neuroscientist has received a new grant from the National Institutes of Health to investigate how a food or drink's temperature affects the way our brains process the taste of salt, a neural mechanism that plays a significant role in shaping eating behaviors and nutrition habits.

Vitamin C supplements during pregnancy may support infant emotional health

New research from Oregon Health & Science University shows that additional vitamin C intake during pregnancy can be an effective, low-cost and accessible intervention to promote infant emotional well-being.

Eating sugary foods more than twice a week was linked to 28% higher breast cancer risk

In a prospective study of 71,264 Korean women followed for an average of 9.2 years, researchers identified 713 breast cancer cases and examined how different dietary sugar sources related to cancer risk. Women consuming high-sugar foods more than twice weekly had a 28% higher breast cancer risk than those consuming them no more than once a month, while total sugar intake and fruit consumption showed no significant association.

Long-term study supports cardiovascular safety of contemporary hormone replacement therapy

Contemporary hormone replacement therapy (HRT) was not associated with an increased risk for heart attack, stroke, blood clots or death among women ages 45 to 59, according to a large, long-term study of over 52,000 women in Israel.

More screen time, less sleep: What researchers observed in children with obesity

A cross-sectional study of 70 children in Spain found that those with obesity reported more daily recreational screen time, shorter sleep duration, and more frequent chronic sleep disturbances than their normal-weight peers. Higher screen-time scores were significantly associated with greater odds of obesity, while the association with sleep disturbances did not reach statistical significance.

Younger adults in America's famous Blue Zone are eating differently

A cross-sectional study of 615 adults in the Loma Linda Blue Zone area and surrounding communities found that vegetarian diets were more common among older adults and Seventh-day Adventists, with vegetarians also reporting significantly lower BMI than non-vegetarians. The findings raise concerns about whether younger generations are maintaining the region's traditional dietary practices, although further research is needed to establish whether vegetarian adherence is declining over time.

Two healthy diets stood out in a study of more than 7,000 adults

In a cross-sectional analysis of 7,256 adults from the Maastricht Study, researchers found that greater adherence to the DASH and Dutch Healthy Diet patterns was associated with higher very-low-frequency (VLF) heart rate variability power, particularly among participants not taking beta-blockers. No significant associations were observed across time-domain HRV measures after full adjustment, and the findings do not establish that these diets improve cardiovascular function.

Researchers explore why male and female brains adapt differently to overeating

Overeating alters neural pathways involved in feeding and metabolism, but how fast do these adaptive changes occur? And do these adaptations occur similarly in males and females?

Study links ultra-processed foods to poorer dietary quality

A higher proportion of ultra-processed food in the diet is generally associated with poorer dietary quality and, among adults, a somewhat higher prevalence of overweight and obesity.

Does choosing organic baby food change its mineral content?

The study of baby foods in France identifies key elements and packaging influences, emphasizing the need for ongoing monitoring of chemical contaminants.

Why you still want dessert even when you're completely full

A 2026 narrative review examines how food liking (pleasure) and wanting (motivation) interact with hunger and satiety to influence food choices, explaining why certain foods may remain appealing even after a satisfying meal. The authors report that food reward can change independently of hunger under specific conditions, but evidence remains limited that these changes reliably predict subsequent eating or improve weight-management outcomes.

Eating walnuts was linked to higher IgG levels, but what does that mean for health?

A two-year randomized trial involving 474 older adults found that daily consumption of 30–60 grams of walnuts was associated with 6% higher total serum IgG concentrations compared with a control diet, with an 11% difference observed among US participants. Walnut consumption did not significantly affect IgM, MDA-LDL or MDA-LDL-specific antibodies, and whether the modest IgG difference has meaningful cardiovascular benefits remains unknown.

Cold showers improve personal health while reducing carbon emissions

How can we encourage people to adopt more environmentally friendly habits? To explore this question, a psychologist at the University of Basel asked participants in a study to take cold showers. Those who stuck with the routine experienced several benefits.

Study finds unexpected lower gut bacterial diversity in vegans

The gut is home to billions of microorganisms. It is a complex ecosystem that regulates many of the body's functions and helps keep us healthy – when it is in balance.

Mayo Clinic enters new medical era with precure research

Mayo Clinic researchers are uncovering the earliest shifts in disease biology - long before symptoms appear - revealing how disease takes root and opening new possibilities to identify, predict and potentially prevent disease before symptoms develop.

Why do we turn to comfort food? A survey of 1,203 adults offers clues

A cross-sectional study of 1,203 UK adults found that stronger expectations of positive emotions from high-fat, salt and/or sugar foods were weakly associated with poorer diet quality and more frequent comfort eating. Negative emotional expectations about many foods also tracked with comfort eating, but the study did not establish whether eating these foods actually changed mood.

Discarded fruit and vegetable parts offer overlooked fiber benefits

Most of us routinely discard the peels, skins, stalks, and seeds of fruits and vegetables at mealtime. But new research from King's College London suggests these scraps could be a valuable – and overlooked – source of dietary fiber, offering potential benefits for both public health and the environment.

Brief dietary changes may prime the immune system for inflammation

Scientists have long known that diet shapes the immune system. Now, a UC San Francisco team has found that even a brief dietary change can substantially change how the body responds to skin irritation, at least in mice.

Worried nuts will cause weight gain? A large review puts that concern in perspective

A systematic review and meta-analysis of randomized trials found that eating nuts modestly reduced body fat and improved cholesterol levels without significantly changing body weight. The review did not establish that nuts rich in monounsaturated fats offered greater body-composition benefits than those rich in polyunsaturated fats.
