Moderate coffee intake may support heart health, AHA says

The American Heart Association finds that habitual coffee consumption is associated with lower risks of several cardiovascular outcomes, although most evidence comes from observational studies. Moderate intake is generally safe for most adults, while energy drinks and individual caffeine sensitivity may increase cardiovascular concerns.

Childhood ultra-processed food intake associates with altered insulin responses

Researchers analyzed dietary and metabolic data from 508 nondiabetic Mexican American children in the SAFARI family cohort, finding that higher ultra-processed food scores were associated with lower insulin sensitivity and altered early insulin secretion measures. The exploratory cross-sectional study did not establish causality, and its multiple comparisons, historical dietary data, and questionnaire-based UPF estimates warrant confirmation in longitudinal studies and trials.

Less sitting in pregnancy is linked to fewer adverse outcomes

A JAMA cohort study of 470 pregnant women found that lower sedentary time, higher light-intensity activity, and more daily steps across pregnancy were associated with fewer adverse pregnancy outcomes. The findings support testing practical “sit less, move more” interventions, but cannot establish cause and effect.

City of Hope launches trial to map how tumors change during immunotherapy resistance

City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the United States with its National Medical Center ranked among the nation's top cancer centers by U.S. News & World Report, has opened an innovative Phase 2 clinical trial designed to map how tumors change as they begin to resist immunotherapy, treatment that improves the immune system's ability to fight disease.

Early electroacupuncture intervention protects pancreatic function in prediabetes

Prediabetes refers to a metabolic state in which blood glucose is higher than normal but has not yet reached the diagnostic threshold for diabetes. It may involve impaired fasting glucose, impaired glucose tolerance, or elevated glycated hemoglobin A1c (HbA1c), and is closely associated with progressive β-cell dysfunction.

Medically tailored grocery deliveries improve blood sugar control among diabetes patients

A study from researchers at top US health insurance and medical services provider Kaiser Permanente, the Food is Medicine Institute at the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University and The George Institute for Global Health found medically tailored grocery deliveries improved blood sugar control among adults living with type 2 diabetes who have public health insurance, when compared with usual care.

Thymus hormone identified as key player in reversing age-related inflammation

Chronic, low-grade inflammation in the body-a phenomenon known as "inflammaging" because it increases with age-has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

High costs continue limiting insurance coverage for GLP-1 medications

Despite growing evidence that GLP-1 medications improve health and are worth their cost, many insurance plans still limit coverage. University of Mississippi researchers are examining why, and where that leaves patients.

Study reveals geographic gaps in breastfeeding initiation across America

A nationwide analysis led by a UC Riverside (Calif.) professor provides one of the clearest pictures yet of where mothers are least likely to begin breastfeeding their babies in the United States and what circumstances associate with lower rates.

Semaglutide vs. liraglutide: Head-to-head study reveals a diabetes risk difference

Researchers compared semaglutide with liraglutide in 57,456 insured adults without recorded diabetes or cardiovascular disease who initiated formulations indicated for chronic weight management. Semaglutide users had a lower risk of incident diabetes, particularly beyond six months of follow-up, but limited cardiovascular events prevented a precise comparison of cardiovascular risk.

Semaglutide fuels rapid growth in US GLP-1RA use as payments rise

Nationally representative US data show GLP-1RA use rose 230% among adults with diabetes and 643% among those without reported diabetes between 2017 and 2022, largely driven by semaglutide. Mean annual out-of-pocket payments decreased, but mean total annual payments per user increased, raising concerns about long-term affordability.

High doses of caffeine from energy drinks cause cardiovascular harm

Previous studies have found that caffeine is the world's most popular stimulant and psychoactive substance, and coffee is the most common way people consume caffeine.

Filtered coffee links to slower biological aging while instant coffee shows the opposite

Filtered coffee consumption was associated with slower biological aging, while instant coffee was linked to faster aging in UK Biobank participants. The cross-sectional findings do not prove causation, but they suggest that brewing method may influence coffee’s relationship with aging biomarkers.

Vitamin D falls short as an add-on treatment for endometriosis

An eight-week randomized trial of 66 women found that adjunctive vitamin D did not significantly or meaningfully improve endometriosis pain or quality of life compared with placebo during dienogest therapy. The results do not support routine short-term adjunctive supplementation, although the brief trial and absence of post-treatment vitamin D measurements leave longer-term effects uncertain.

Frequent TV watching may harm long-term brain health

"Turn off that TV, it'll rot your brain!" has been a household refrain for decades. While "rot" might be too strong a term, researchers are finding that the overall sentiment could have some merit.

Study reveals how adolescent brain remodeling reshapes memory retrieval

Scientists have long known that the human brain continues developing well beyond the teenage years, with important changes involving decision-making and emotional regulation extending into the mid-to-late 20s.

Popular diabetes drugs do not alter the risk of developing a blinding eye condition

An estimated 27% of U.S. adults with diabetes are using glucagon-like peptide-1 receptor agonists (GLP-1 RAs) - a type of medication that mimics the GLP-1 hormone - to lower blood sugar and support weight loss. Some research has suggested that their use can reduce the risk of developing other diseases.
