Professional nutritionists point out that grapes are warm and sweet, which can nourish liver and kidney, promote fluid production to quench thirst, strengthen bones and muscles, tonify qi and blood, and induce diuresis to relieve stranguria. They can be used for adjuvant treatment of diseases such as spleen deficiency, shortness of breath, edema and dysuria. The most important thing is that grapes help pregnant women to protect their babies. But you should also pay attention to some things when eating grapes, and don't eat too much.

First, you can't drink water immediately after eating grapes.

Drink water immediately after eating grapes, and you may have diarrhea in less than a quarter of an hour. This is because grapes themselves have the effect of relaxing bowels and moistening intestines. Drinking water immediately after eating grapes dilutes the gastric acid before the stomach digests and absorbs water. Grape, water and gastric acid are rapidly oxidized and fermented, which accelerates intestinal peristalsis and produces diarrhea.

Second, don't drink milk and eat grapes.

Grapes contain vitamin C, and some ingredients in milk will react with vitamin C contained in grapes, which is harmful to the stomach. Taking both at the same time can also cause diarrhea and vomiting in severe cases.

Third, don't eat grapes after eating seafood.

Eating fruits such as grapes, hawthorn, pomegranate and persimmon while eating seafood will cause vomiting, abdominal distension, abdominal pain and diarrhea. Because these fruits contain tannic acid, tannic acid will solidify and precipitate when it meets protein in seafood, forming indigestible substances.

Fourth, you should not eat too much grapes.

Because of the high sugar content of grapes, diabetics should pay special attention to avoid eating grapes. Pregnant women should beware of diabetes during pregnancy, so pregnant women should eat grapes in moderation. It is advisable to eat grapes every 4 hours before eating products, so as to avoid tannic acid in grapes and calcium in aquatic products from forming substances that are difficult to absorb and affecting health.
