Yogurt, prebiotics, and probiotics link to lower colorectal cancer odds in U.S. adults

A national NHANES analysis of 9,405 U.S. adults aged 50 and older found that any yogurt, prebiotic, or probiotic consumption was associated with about 50% lower odds of self-reported colorectal cancer. Because the study was cross-sectional, it cannot prove causation but supports further research into microbiota-targeted dietary strategies.

Updated ABCs framework gives clinicians a clearer path to prevent heart disease

A 2026 State-of-the-Art review updates the ABCs of cardiovascular disease prevention to help clinicians apply contemporary risk assessment, lifestyle, pharmacologic, and cardiometabolic strategies in routine care. The framework emphasizes PREVENT™ risk equations, Life’s Essential 8, CKM syndrome, obesity care, lipid lowering, blood pressure control, healthy aging, heart failure prevention, and atrial fibrillation management.

Study links semaglutide and tirzepatide to fewer anxiety and depression diagnoses in obesity care

A US electronic health record study found that adults with obesity who started semaglutide or tirzepatide had lower recorded hazards of anxiety and depression than matched patients using naltrexone-bupropion. However, among adults without type 2 diabetes, tirzepatide was linked to higher recorded hazards of anxiety and insomnia than semaglutide, underscoring the need for cautious monitoring.

Early diabetes drug treatment links to better survival after diagnosis thresholds

A Korean target trial emulation found that starting antidiabetic medication within 12 months of newly crossing type 2 diabetes diagnostic thresholds was associated with lower five-year all-cause mortality. MACE risk was numerically lower with earlier treatment, but the reductions in cardiovascular events were not statistically significant, underscoring the need for larger studies.

Elite athletes with higher vitamin D show healthier lipid profiles

Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

Oral semaglutide improves blood sugar, weight, and liver markers in real-world diabetes care

A nationwide Finnish registry study of 7,249 GLP-1RA-naïve adults with type 2 diabetes found that once-daily oral semaglutide was associated with 12-month improvements in HbA1c, body weight, lipid markers, and ALT.

Oral GLP-1 drug elecoglipron helps adults lose up to 11.8% body weight

Once-daily oral elecoglipron produced dose-dependent weight loss in adults with obesity or overweight without diabetes, with mean reductions reaching 10.5% at 26 weeks and 11.8% at 36 weeks in the highest-dose weekly-titration group. The phase 2 trial found no evidence of a weight-loss plateau by 36 weeks, while gastrointestinal adverse events were common but generally manageable.

Extreme trait values often have simpler genetic explanations than thought

Researchers at the Icahn School of Medicine at Mount Sinai have found evidence that people who fall at the extreme high or low ends of certain traits, such as cholesterol, blood glucose, height, and age at menopause, are more likely to have a simple genetic explanation than previously thought.
