Can you eat grape skins?
When people eat grapes, they often spit out the skins because grape skins have an astringent taste. However, from a nutritional perspective, you should not spit out the skins when eating grapes.
Grape skins are rich in a type of polyhydroxy phenolic compound—resveratrol, which has the effects of lowering blood lipids, preventing thrombosis, preventing arteriosclerosis, and enhancing immunity.
Another important substance in grape skins—tannin, has the effects of anti-allergy, anti-aging, enhancing immunity, and preventing cardiovascular and cerebrovascular diseases.
The anthocyanins contained in grape skins have strong antioxidant, anti-mutagenic, liver function protection, and cardiovascular protection functions.
Grape skins also have anti-cancer effects. Researchers at the University of Illinois College of Pharmacy in the United States have found that this substance exists to varying degrees in more than 70 plants, such as peanuts and grapes, and is most abundant in grape skins and red wine.
Because most grapes on the market currently have pesticide residue problems, they must be washed thoroughly before being eaten with the skins.
