NCT04015544

Brief Summary

The primary purpose of this study is to determine the effectiveness of six weeks of watermelon puree supplementation, compared to control (no treatment), on blood antioxidant capacity, inflammation markers in the blood, biomarkers of metabolism in the blood, and cardiovascular disease markers in the blood, and biomarkers in the blood related to watermelon ingestion in overweight post-menopausal women. The secondary purpose is to compare body composition and body mass between the watermelon supplement group and the control group.
