Grape seeds are a good source of antioxidants, but that doesn't mean you have to eat grapes with seeds. Because when grape skins and grape seeds are chewed and swallowed, a large amount of tannins will coagulate protein on the surface of the tongue, mouth and esophagus, resulting in strong astringency and damage to the digestive tract, and the effective components in them will still pass through the intestine and are not easily absorbed by the human body. Resveratrol and polymerized procyanidins can only play their nutritional role if they are dissolved in the mixture of ethanol and water and made into wine. Therefore, the best way to fully absorb the nutrients in grapes is to drink wine.
