How do everyday spices help protect the heart?

A Nutrition Reviews supplement article reviewed controlled studies showing that culinary spice and herb blends may improve selected cardiometabolic risk markers, including post-meal triglycerides, insulin responses, inflammation, endothelial function, and 24-hour blood pressure. The review also highlighted exploratory evidence that spices and herbs may influence immune-cell activity, circulating phytochemical metabolites, and gut bacterial composition, while emphasizing the need for longer and more diverse studies.

Can AI help build a fairer food system from farm to plate?

AI could help make food systems more personalized and climate-resilient by linking nutrition, health, farming, logistics, and sustainability data. The review highlights promise in precision nutrition, vertical farming, traceability, and smarter supply chains, while warning that privacy, equity, energy use, data silos, and governance gaps must be addressed.

Persistent gut microbiome changes linked to sustained colorectal cancer risk

More than a decade after removal of an adenoma-a precancerous mass-from the colon, alterations to the gut microbiome and metabolites remain and may drive heightened risk of colorectal cancer (CRC), according to a new study led by researchers at Harvard T.H. Chan School of Public Health.

How the right diet could support the gut bacteria that matter most

This review examines how gut keystone bacteria shape microbiome stability, disease risk, and responses to diet. It highlights why better identification methods, experimental validation, and precision diet-probiotic strategies are needed to restore gut homeostasis.

Retatrutide reshapes metabolism in obesity and type 2 diabetes, study finds

Retatrutide altered circulating metabolites and lipids linked to fatty acid oxidation and insulin resistance in people with obesity, with or without type 2 diabetes. These biomarker changes suggest improved metabolic health, but the post-hoc analysis remains hypothesis-generating and does not prove direct clinical benefit.

New online toolkit helps clinicians integrate nutrition into patient care

A new online resource aims to help health care providers turn a growing body of research on nutrition and health into effective care for patients.

Diet and inflammation may play a role in progressive vitiligo

A small case-control study linked higher Dietary Inflammatory Index scores with progressive vitiligo, suggesting that pro-inflammatory dietary patterns may be associated with disease occurrence or progression. The findings support further research into diet, inflammation, and the gut-skin axis as potential targets for vitiligo prevention and management.

Indian adapted Mediterranean diet targets inflammation in heart disease trial

The paper describes a single-center randomized controlled trial testing whether an Indian Adapted Mediterranean Diet can reduce dietary inflammation in adults with stable coronary artery disease or moderate-to-high cardiovascular risk. The protocol will assess changes in the Dietary Inflammatory Index, inflammatory biomarkers, cardiometabolic risk factors, body measurements, and metabolic hormones over six months.

Novel RNA modification mechanism drives metabolic fatty liver disease progression

Nonalcoholic fatty liver disease (NAFLD) is a prevalent metabolic disorder with a complex pathogenesis. Although epitranscriptomic modifications such as N6-methyladenosine (m6A) have been implicated in NAFLD, the role of N1-methyladenosine (m1A) and its regulators is largely unexplored.

Outdoor running combats winter vitamin D deficiency better than supplements

An EHU study says that vitamin D supplements can help to strengthen the immune system, but not to improve athletic performance.

Food insecurity links to poorer mental and physical health in Tasmania

Food insecurity among adults in Tasmania was strongly associated with lower diet satisfaction and poorer self-rated mental and physical health, with diet dissatisfaction showing the strongest link. The findings suggest that food insecurity limits not only nutrition, but also food choice, agency, wellbeing, and equitable access to acceptable, affordable, and culturally appropriate diets.

CDC report reveals what 24 years of nutrition biomarkers say about America’s health

The 2026 CDC Nutrition Report will make nearly 24 years of NHANES biomarker data easier to use, covering up to 131 nutritional biomarkers in the US population aged 1 year and older. By standardizing blood and urine biomarker trends, demographic patterns, and comparisons of supplement use, the report aims to support nutrition policy, clinical reference intervals, and public health monitoring.

Yoga and meditation show promise for gut health

This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.

Tulane study explains why gut damage persists despite HIV treatment

For many people living with HIV, today's treatments can suppress the virus and dramatically improve health. But even when HIV is controlled, damage to the gut caused by the disease can persist, fueling chronic inflammation linked to serious health problems.
