The efficacy, function and medicinal value of grape skin

Grapes are a fruit that many people like to eat. They are sweet, juicy and nutritious, but when people eat grapes, they often spit out the slightly bitter skin, not knowing that the grape skin is more edible than the grape pulp. In fact, grape skin is also a highly nutritious food. Its anthocyanin content is much higher than that of grape pulp, and it has excellent health benefits after consumption.

1. Protect the heart and prevent high blood pressure

Grape skin is the protector of the human heart. This food ingredient is rich in flavonoids and some trace elements such as magnesium. These substances can improve human heart function, enhance myocardial contractility, accelerate blood circulation, and keep people's blood pressure in a stable and normal state. It has a significant preventive effect on the high blood pressure that often occurs in humans today.

2. Prevent cancer

Grape skins contain resveratrol, a natural anti-cancer ingredient that can prevent human tissue cells from becoming cancerous. The flavonoids and phenolic components contained in grape skins can inhibit the activity of nitrosamines, a carcinogen in the human body, and enhance the body's own immunity, which are of great benefit in preventing cancer.

3. Prevent hyperlipidemia

Eating more grape skins can effectively prevent the occurrence of hyperlipidemia, because the cellulose and pectin they contain are much higher than grape pulp. They can inhibit the body's absorption of cholesterol, purify the blood, accelerate the decomposition and metabolism of cholesterol in the blood, and reduce the triglyceride content, thereby reducing the occurrence of hyperlipidemia.

4. Delay aging and prolong life

When people eat grapes, if they eat the skins instead of spitting them out, they can also absorb a large amount of anthocyanins, trace element selenium and flavonoid glycosides. These substances are natural antioxidants that can reduce the occurrence of oxidative reactions in the human body, eliminate accumulated free radicals in the body, enhance the body's own immunity, delay aging and prolong life.
