Effect of Watermelon on Gut and Cardiometabolic Health
Effect of Daily Fresh Watermelon Consumption on Gut and Cardiometabolic Health in Young Adults With Overweight and Obesity
Source: ClinicalTrials.gov · Last updated 9 Apr 2026
Brief summary (registry, in English)
The goal of this clinical trial is to evaluate the effect of daily fresh watermelon consumption for 6-weeks on gut health, including microbiome diversity, gut barrier and immune function in young adults with overweight and obesity. The main questions it aims to answer are: 1. Will consuming fresh watermelon daily for 6-weeks will improve intestinal barrier health and increase microbiome diversity such as an increased population of beneficial 'probiotic' bacteria when compared to control participants consuming a low-fat snack? 2. Will consuming fresh watermelon daily for six-weeks will improve other health measures, including body-composition, blood pressure, blood vessel function, blood lipid profiles, and measures of inflammation, as compared to control participants consuming a low-fat snack for the same time period?
