Grapes are rich in edible value and nutritional value, but we should not eat more grapes, otherwise it will also lead to some health problems, especially for diabetics, because grapes have high sugar content, which will easily lead to high blood sugar.
Precautions for eating grapes:
1, if you eat too much grapes, you will have constipation. The high heat content of grapes is not suitable for people with yin deficiency and internal heat and constipation.
2, grapes are rich in sugar, eating more will easily lead to increased blood sugar, and diabetics must be careful to eat.
3, eating a lot of grapes and then drinking water can easily lead to diarrhea. Grape itself has the effect of relaxing bowels and moistening intestines. Drinking water immediately after eating grapes will dilute gastric acid before the stomach can digest and absorb water. Grape, water and gastric acid are rapidly oxidized and fermented, which accelerates intestinal peristalsis and produces diarrhea. And grapes can't be eaten with milk and seafood, because grapes contain fruit acid, which will coagulate protein in milk and seafood, which will not only affect absorption, but also cause abdominal distension, abdominal pain, diarrhea and other symptoms in severe cases.
4, eating a lot of grapes and then drinking water can easily lead to diarrhea.
5, grapes contain a variety of fermented sugars, which are highly corrosive to teeth, and it is easy to cause dental caries when eaten in large quantities.
Extended data:
A little knowledge about grapes:
1, the relationship between grape size and nutrition:
There is no necessary connection between the two. Because the size of grapes is influenced by many factors, such as variety, field management, weather and so on, it is unscientific to link the size of grapes with nutrition.
Grape varieties used for wine-making generally require small fruit grains, thick peel, seeds and high juice yield; However, table grapes generally pursue large fruit, thin skin, beautiful appearance and few seeds.
2. Frost on grapes:
Frost on grapes is a sugar alcohol substance secreted by fruits and vegetables themselves, also known as fruit powder, which belongs to a biosynthetic natural substance. These compounds are insoluble in water, so they can't be completely removed by soaking, washing and rubbing.
Grape is a kind of fruit that is not easy to be infected with insects. Now, bagging is mostly used in planting, and the probability of using high-concentration pesticides is very small. If it is determined that it is the hoarfrost of grape itself, it is not necessary to wash it off.
Distinguishing method between hoarfrost and pesticide: Normal "hoarfrost" is distributed naturally and evenly, and does not cover the color of grape skin itself, which makes grapes look more beautiful. The appearance distribution of pesticide "hoarfrost" is uneven, and there will be dark blue traces in it.
3, grape skin:
Grape skin contains resveratrol, which has certain effects of reducing blood lipid, preventing arteriosclerosis and enhancing immunity. Among them, anthocyanins have strong antioxidant and cardiovascular protection functions, so it makes sense to "eat grapes without spitting grape skins".
