Do you spit grape skin when eating grapes?
The nutritional content of grapes.
The function of grapes: 1. The sugar in grapes is mainly glucose, which can be quickly absorbed by the human body.
When hypoglycemia occurs in the human body, if grape juice is added in time, symptoms can be relieved quickly; 2. French scientists have found that grapes can better prevent thrombosis than aspirin, and can lower human serum levels and plateletsThe cohesive force has a certain effect on the prevention of cardiovascular and cerebrovascular diseases; 3, the flavonoids contained in grapes are a powerful antioxidant, which can fight aging and remove free radicals in the body; 4, grapes contain an anti-cancer microbial elementResveratrol) can prevent healthy cells from becoming cancerous and prevent spread.
Grape juice can help patients with organ transplant surgery reduce rejection and promote early recovery.
The best cleaning steps for grapes: Step 1. When washing the grapes, first remove the rotten grapes. Use scissors to cut the grapes at the junction between the grapes and the fruit.
Do not cut the peel, it is easy to contaminate the flesh when washing after peeling, and do not leave a small section of stems. Grapes with small stems are not easy to clean, and it is also easy to stab other grapes.
Tip: Do not remove the fruit from the ear, so the stem will bring out the fruit brush in the grape, leaving a hole in the fruit, and the flesh is easy to rot.
After cutting the ears, you can see that the situation where the grapes meet is intact.
Step 2: Put the grapes in the basin, add some water, squeeze some toothpaste in your hands, rub your hands, then gently scrub the grapes.
Step 3. Drain the dirty water and rinse it with water.
Step 4. Rinse with fresh water until there is no foam. Rinse well and place in a sieve and drain. Then use a flat dish, spread a clean towel, and pour the grapes into it, about one layer of grape thickness at a time.Shake the pan to make the grapes roll evenly.
In this way, the remaining moisture can be absorbed.
Special reminder: the entire washing process should be fast (within five minutes), so as to avoid the grapes absorbing water and bursting and easy to rot.
The above measures try to ensure that the grapes do not come into contact with too much water before eating, otherwise, the grapes will easily crack and rot, and will lose most of the nutrients and effective ingredients.
In addition, the grapes should be washed when they are eaten, because they will break easily if they are not eaten after washing.
After washing, even if kept in the refrigerator, it can only be kept for two or three days.
Should I eat grapes?
Grape skin contains anthocyanins. In addition to anthocyanins, grape skin also contains another antioxidant: resveratrol.
Both types of substances are good for the human body.
So, when we eat grapes, do we even swallow the seeds (the content of proanthocyanidins in grape seeds) is swallowed together to get the protection of these powerful antioxidants?
First, current food safety issues are becoming less and less satisfactory.
The author has planted a grape before, knowing that grapes use a large amount of pesticides and it is easy, and it is impossible to produce grapes without spraying.
Commercially available grapes start from flowering, generally 7?
The fungicide should be sprayed once every 10 days. In the later stage, in order to prevent grape anthracnose from harming the grape fruit, it is necessary to spray the fruit regularly.
These pesticides cannot be completely removed during the washing process.
At present, there are many detergents on the market that claim to be able to remove pesticides from fruit surfaces, and the actual effect is not as good as the publicity.
First, the antioxidants such as proanthocyanidins and resveratrol in grapes are not very soluble in water (resveratrol is more difficult to dissolve in water).
Anyone who has studied nutrition knows that nutrients must be dissolved in water or trace amounts to be absorbed by the body.
Low solubility means that most of these nutrients will pass through the intestines and fail to achieve the desired effect.
Therefore, for your own health and safety, it is better to let go of the rich cellulose and antioxidants that are not easily absorbed in the grape skin.
