Grapes are a rich source of fiber and polyphenols. Grapes increase diversity of gut bacteria and reduce cholesterols.
- Grapes increase microbial diversity, which help improve your gut health
- Grapes are a rich source of fiber and polyphenols
- Also, helps reduce cholesterol levels, thereby, lowering heart disease risk
In the intervention study, conducted at the University of California, Los Angeles, and led by principal investigator Zhaoping Li, M.D., Ph.D., healthy subjects consumed the equivalent of 1.5 cups of grapes per day – for four weeks.
The subjects consumed a low fiber/low polyphenol diet throughout the study.
After four weeks of grape consumption there was an increase in microbial diversity as measured by the Shannon index, a commonly used tool for measuring diversity of species.
Among the beneficial bacteria that increased was Akkermansia, a bacteria of keen interest for its beneficial effect on glucose and lipid metabolism, as well as on the integrity of the intestinal lining.
Bile acids, which are linked to cholesterol metabolism, were decreased by 40.9%.
This study deepens our knowledge and expands the range of health benefits for grapes, even as the study reinforces the heart health benefits of grapes with lowered cholesterol.
