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.

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.

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.

Higher ferritin threshold could detect childhood iron deficiency much earlier

Many cases of iron deficiency in school-aged children could be diagnosed earlier, according to a new study published in Blood Red Cells & Iron, a journal of the American Society of Hematology (ASH).

Pregnancy-related disorders may shape offspring heart health into adulthood

Hypertensive disorders in pregnancy may lead to lasting cardiovascular issues in offspring, highlighting the need for improved maternal health strategies.

New therapies could help type 1 diabetes care move beyond insulin alone

Disease-modifying therapies for type 1 diabetes are beginning to move care beyond insulin replacement by targeting immune dysregulation, beta-cell stress, and preservation of endogenous beta-cell function. Teplizumab marks a major clinical milestone, but the review emphasizes that durable metabolic remission will likely require earlier screening, better patient selection, and sequential or combination therapies.

Once-daily orforglipron helps preserve weight loss after semaglutide or tirzepatide

Oral orforglipron helped adults maintain clinically meaningful weight loss after prior injectable tirzepatide or semaglutide therapy. The phase 3b ATTAIN-MAINTAIN trial suggests switching to once-daily oral therapy may help reduce weight regain when injectable treatment is discontinued.

Could GLP-1 drugs help breast cancer patients live longer?

A large retrospective cohort study of adult female breast cancer patients found that GLP-1 receptor agonist use was associated with better all-cause survival and recurrence-free survival in patients with obesity or type 2 diabetes. The strongest associations were seen versus non-use in obesity and versus insulin or metformin in type 2 diabetes, while comparisons with SGLT2 inhibitors were less consistent and require further study.

New AI chip identifies meibomian gland dysfunction within milliseconds

A research team from Peking Union Medical College Hospital and Tsinghua University has developed a compact optical AI chip that can identify meibomian gland dysfunction (MGD)-a major cause of dry eye disease-with more than 96% accuracy by analyzing the tissue's spectral signatures.

Why are so many mothers missing diabetes follow-up after childbirth?

A New York City cohort study found that few women with postpartum-onset diabetes received guideline-recommended A1C monitoring over three years. Non-Hispanic Black women and mothers with more children faced lower monitoring rates, while Medicaid coverage was linked to better follow-up.

Two leading heart risk tools pass a major global test

A multinational Nature Medicine validation study found that PREVENT and SCORE2 cardiovascular risk equations performed generally well across 6.4 million people from observational cohorts and randomized trials. The findings support broader use of these tools for CVD risk stratification, while highlighting the need for local calibration and more validation in underrepresented regions.

Postpartum diabetes monitoring remains low among many new mothers

Few women with postpartum-onset diabetes meet recommended A1C monitoring guidelines, highlighting a need to improve routine diabetes care-particularly among Black women-according to new research at Columbia University Mailman School of Public Health.

Targeting a parasite-specific enzyme offers new hope for malaria treatment

Research published in The FEBS Journal may help overcome challenges to the treatment of malaria-a tropical disease caused by infection of red blood cells with Plasmodium parasites, which are transmitted through infected mosquito bites.

Semaglutide as a promising new treatment for alcohol use disorder

Research indicates semaglutide can significantly decrease alcohol consumption and cravings in individuals with comorbid obesity and alcohol use disorder.

GLP-1 drugs promise wider health benefits, but experts urge caution on use

GLP-1 receptor agonists are reshaping care for type 2 diabetes, obesity, chronic kidney disease, and obstructive sleep apnea, with evidence for glycemic, weight-loss, cardiovascular, and renal benefits. The review urges nurse practitioners to balance expanding clinical promise with careful prescribing, patient education, monitoring, access advocacy, and vigilance for gastrointestinal, endocrine, pregnancy-related, and rare serious risks.

Yoga to help manage obesity-related heart and metabolic risks

The impact of yoga on heart health in obesity is modest, suggesting it as a complementary approach for improving metabolic outcomes in high BMI populations.

Scientists will probe whether processing itself makes ultra-processed foods harmful

A randomized controlled trial protocol will test whether the cardiometabolic risks linked to ultra-processed foods stem from industrial processing, poor nutrient composition, or both. Using four controlled diets, researchers will separate the effects of UPF content from saturated fat, added sugar, and sodium on LDL cholesterol, insulin resistance, and blood pressure.

Intercellular heme transfer pathway sustains red blood cell production under stress

Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry oxygen to tissues, even after shedding the vital structures they need to produce it.

Tirzepatide vs. semaglutide: Study compares cost and health outcomes in obesity

In a US societal-perspective lifetime simulation based on SURMOUNT-5 data, tirzepatide was projected to deliver lower total costs and better health outcomes than semaglutide for adults with obesity or overweight without type 2 diabetes.
