According to the study report, all participants consumed 46 grams of grape powder for a month – about one and a half cups of berries. In parallel, the study participants ate foods with low levels of fiber and polyphenols, which are found in abundance in grapes. One month later, all participants had their gut microbiota levels measured.
It turned out that thanks to this plant, there were not only a lot of beneficial bacteria, but their diversity was also recorded. Among other microorganisms, there has been an increase in bacteria such as Ackermannsia, which improves the metabolism of glucose and peptides, and also maintains the integrity of the intestinal mucosa.
At the same time, the total cholesterol of all participants decreased by 6.1%, and bile acids – by 40.9%, and the level of low-density cholesterol also decreased – by 5.9%.
