Why you should eat grapes “with skin” [푸드인사이트]

This is an angle that points to hot problem-causing foods or foods that are good to eat at this time.
Clinical nutritionists introduce the nutrition and efficacy of foods, how to choose, how to store and how to eat.

The berries are savory and soft, with an excellent sweet and sour flavour. There are many ways to eat grapes, but the important thing is to eat them with the peel. Let’s find out why.

Grapes that are effective in relieving fatigue, antioxidants and improve cholesterol levels
Grape is rich in various nutrients enough to be called the queen of the fruit world, which has a good effect on health. It is rich in vitamin C, vitamin B1 and vitamin B2 along with moisture and organic acids, so it is good for skin health and fatigue recovery. Furthermore, it is rich in polyphenols such as tannins, catechins and anthocyanins, which act as antioxidants, anticancer and antibacterials. Potassium, which is abundant in grapes, aids in the excretion of sodium and prevents blood pressure from rising. In one study, 15 g of grape pectin was given to 200 people for 4 months for 4 months, and as a result of examining blood cholesterol levels, it was reported that LDL cholesterol was significantly reduced and the ratio of HDL-cholesterol was increased.

Polyphenols – flavonoids and resveratrol, more abundant in the peel than in the pulp
The representative function of many polyphenols in grapes is their strong antioxidant function. Among the polyphenols, flavonoids act as very powerful antioxidants in our body to prevent cardiovascular diseases and act as anticancer agents. Grapes are a representative food rich in flavonoids. It is particularly abundant in the peel rather than the pulp. Grape skins are rich in flavonoids and resveratrol. Resveratrol is a substance known to have anticancer, antiviral, neuroprotective and antidepressant effects. In a national study comparing resveratrol content by grape variety, the seedless variety, which is easy to eat with the skin on, had the highest content at 14.36 mg/100 g. Another internal study investigated the content of functional components in grape matsutake pulp, skin, seeds and branches.

grape skins. The main causes of the French paradox
Flavonoids and resveratrol are effective in the prevention of cardiovascular diseases such as arteriosclerosis by preventing the accumulation of lipid peroxides in blood vessels. Among countries that consume a lot of animal fat, the French paradox, which means that only the French have a very low incidence of heart disease, is also because the French often drink wine made from fermented grape skins. That’s why we should eat grapes with their skin on.

You don’t have to worry about white powder on the skin of the berries because the sugar in the berries itself isn’t a harmful substance, but it just floats to the surface. Rather, the state of white powder on the surface is the state of good taste of the grape. However, it is good to wash it lightly with water to remove pesticide residue and dust. When washing grapes, it is best to soak them in water for 1 to 2 minutes and shake them several times rather than washing them with running water. This alone removes most pesticide residues. A few drops of baking soda or vinegar can also help.
