Why does eating grapes cause diarrhea

Grapes are rich in nutrients and contain many nutrients that are good for human health. Women can eat more of it to supplement iron and beautify themselves. However, there are many things to pay attention to when eating grapes. If you eat them with other foods such as persimmons or crabs, it may affect the absorption of nutrients. In addition, if you drink water immediately after eating grapes, you are very likely to suffer from diarrhea. So what is going on?

Grapes cannot be eaten with the following things.

seafood

Everyone knows that persimmons cannot be eaten with crabs. This is because persimmons contain tannic acid and crab meat is rich in protein. When the two meet, they coagulate into tannic acid protein, which will hinder digestion. The sour feeling of grapes is actually the taste of tannic acid. If grapes are eaten in large quantities with crabs or seafood, there is also a risk of poisoning from eating persimmons and crabs together. Therefore, it is best to separate grapes and seafood by four hours.

milk

Grapes will increase the acidity of the stomach and intestines, making milk difficult to digest and absorb, and in severe cases may even cause diarrhea.

Iron supplements , calcium supplements

Tannic acid is like a "magnet". If you are taking iron and calcium supplements, do not eat them with grapes, because the iron and calcium in them will be absorbed by the tannic acid, and the iron and calcium will coagulate together and form stones. It is recommended to wait half an hour before eating.

Drink water immediately after eating grapes

Drinking water immediately after eating grapes may cause diarrhea within a quarter of an hour. Because grapes, water, and stomach acid rapidly oxidize and ferment, which accelerates intestinal motility, diarrhea occurs.

Sulfonamides , digestive enzymes

Grapes contain acidic ingredients such as tartaric acid, which can change the acidity of the stomach and intestines and affect the absorption of drugs. Sulfonamides used to treat urinary tract infections are highly soluble in alkaline environments but tend to crystallize in acidic environments. Some digestive enzyme drugs can work well in alkaline environments, but they are easily destroyed in overly acidic environments, thus losing their efficacy. It is best to take the above-mentioned medicines half an hour apart from grapes.
