About the study
We are examining whether consuming a fiber-enriched soda (Olipop) before a high-fat meal leads to a more favorable cardiometabolic response than when consuming a control beverage before the same high-fat meal.
What is being tested
- Prebiotic soda followed by high-fat meal (other)
- Control beverage followed by high-fat meal (other)
