Study Overview
Brief Summary
Mango is rich in bioactive compounds such as dietary polyphenols and carotenoids, which may explain its beneficial effect on health. Polyphenols accumulate in the gut where they can positively modulate the microbiota. As gut microbiota may have a strong influence on cardiometabolic health, we hypothesize that mango consumption improves metabolic profile in overweight or obese individuals through beneficial changes in gut microbiota. The study of metagenomics, transcriptomics and metabolomics will be used to validate this hypothesis.
