Are grape skins and grape seeds really more nutritious than pulp?

Personally, I think the nutritional value of skin and seeds is higher than that of meat.

If the grape is regarded as a cell, then the skin is the cell wall = the stratum corneum that protects the cell.

The seed is the nucleus = it can decide whether the cell is male or female.

The pulp in the middle layer = cytoplasm, which provides nutrition for the growth of nucleus and cell wall.

But people can't live by nutrition alone, they need something special.

There is a doggerel that says better, eat grapes without spitting grape skins, and eat grapes without spitting grape skins. If you don't spit grape skins here, it means that grape skins can be eaten. Since the nutritional value of grape seeds was discovered, many people just chewed them up and ate them. Then come down and talk professionally about whether grape skins and grape seeds can be eaten. Their nutritional value.

Grape skin contains a kind of resveratrol, which is an amine compound, which can prevent cardiovascular and cerebrovascular diseases and has strong anti-cancer ability. Moreover, this substance is more than grape seed and grape meat, so grape skin is more nutritious. There is also a flavonoid in purple grape skin that can lower blood pressure and promote the increase of high-density protein in blood, thus reducing cholesterol content and better protecting the heart. Grape seed contains a kind of grape polyphenol, also called anthocyanin, which has strong antioxidant capacity and can resist oxidative aging of skin, so it is very popular among women.
