Grapes contain many essential nutrients, such as vitamins, minerals, proteins and fats. The grapes are sweet and sour, so they are loved by many people. But when we were eating grapes, we couldn't stand the taste of grape skins, but we also felt that grape skins were of little use and were not clean. Therefore, we all had the habit to spit out the grape skins. In fact, this practice was wrong. As long as the skin is clean, it is still good to eat it. Here we have a look at the effectiveness and role of grape skin.

Grape skin contains resveratrol
Resveratrol is a polyphenolic compound. In addition to this ingredient in grapes, peanuts, mulberry and other foods also contain this element. It has a strong biological activity and is a type of drug that is inferior to mold. The resulting phytoalexins, in addition to being energetic, can also prevent cardiovascular and cerebrovascular diseases and fight cancer.
Grape skin resists high blood sugar
The grape skin always contains natural pigments, which can actively promote the decomposition of sugars in the human body and can effectively counteract the effects of high blood sugar. It can also avoid the problem of poor digestion caused by eating too many grapes.

What to watch for grape skin
When eating grape skins, it is important to wash away impurities and pesticide residues on the surface of the grape skins. When cleaning, add a little salt and flour to the skin and gently knead it. After washing several times, dry it and serve.
