A natural way to lower cholesterol might be as close as the produce section of your favorite market: New study in the journal Nutrients suggests that grapes may not only improve this marker of heart health, but also increase the diversity of your beneficial gut bacteria.

Researchers asked 19 healthy adults to follow a diet low in fiber and polyphenols – the compound in fruits and vegetables that reduces inflammation and helps regulate blood pressure – for a month to see how the powder of grapes would subsequently affect them. They continued to eat the same diet but added 46 grams of powder, the equivalent of two servings of fresh grapes, which comes in two cups.

After four weeks of daily grape powder, participants all saw an increase in the diversity of gut bacteria, particularly a type associated with glucose regulation and fatty acid breakdown. They also recorded an almost 8% drop in “bad” cholesterol levels, as well as a 40% drop in steroid acids, a substance that plays a role in how cholesterol works in the body. In large amounts, these acids can cause blood vessels to clog, increasing the risk of heart attack and stroke.
