Previous research has already shown that eating certain fruits, such as apples and grapes, can promote blood vessel health because they contain polyphenols, which are antioxidants. Eating these fruits also reduces the levels of blood sugar and blood pressure.
On the other hand, in some cases, it has been shown that the consumption of polyphenols reduce the inflammation, a contributing factor to heart disease.
In this new study, the researchers looked at other possible health benefits of eating grapes.
To learn more regarding the possible positive health benefits, the group enlisted the help of 19 healthy adults.
Each volunteer ate a special diet low in polyphenols and fiber for four weeks. Then, each subject ate the same diet but adding grape powder. The volunteers took 46 grams of powder per day, which is equivalent to two servings of grapes.
Specifically, the levels of the bacteria increased akkermansia, which is known to have a positive impact on glucose levels and lipid metabolism. The researchers also found a decrease in the overall cholesterol levels of the 6.1% and a 5.9% drop in LDL.
Finally, it was also detected that some steroid acids in the bile were reduced by 40.9%.
