Summary
This trial studies how regular/skim milk & full-fat/fat-free yogurt affect gut bacteria & heart health risk factors. Results may help refine dietary guidance for CVD risk reduction.
Who is the study for?
This trial is for men and postmenopausal women over 50 with a BMI between 25-35, who don't smoke, have regular bowel movements, and are not on certain medications. Excluded are those underweight or overweight beyond the set limits, recent smokers or nicotine users, hormone therapy recipients, anemia patients within two years, recent blood donors or antibiotic users.
What is being tested?
The study tests how full-fat and fat-free milk and yogurt affect gut microbes and heart disease risk factors. Participants will consume these dairy products to see if fat content and fermentation influence cardiovascular health.
What are the potential side effects?
Potential side effects may include changes in digestion due to different fat contents in dairy products. Full-fat options might impact cholesterol levels more than fat-free ones.
