First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether eating 2.5 cups of fresh watermelon every day for six weeks can improve gut health, including increasing good bacteria, and boost heart health in young adults aged 18-30 who are overweight or have obesity. Participants will be randomly assigned to eat either watermelon or a low-fat control snack. Researchers will measure changes in gut and mouth bacteria, digestion speed, and blood vessel function.
