Persimmons and crabs can inhibit the secretion of digestive juice and affect health. In addition, because they are all cold foods, they will cause gastrointestinal diseases after eating, so they should not be eaten together. Tannic acid in persimmon can precipitate with protein and calcium salt in fish, shrimp and other foods, and can stimulate gastrointestinal organs, easily causing nausea and constipation.

Not suitable for eating with octopus.

Octopus is sweet, salty and cold, non-toxic, cold and not diarrhea, and can nourish blood and replenish qi. Persimmon is sweet, astringent and cold, because both of them belong to cold medicine, so they can't be eaten together, otherwise it will damage intestinal absorption and easily lead to diarrhea. At the same time, octopus is also a high-protein food. Protein in persimmon meets tannic acid, which is easy to condense into protein tannic acid, which can cause vomiting, abdominal pain, diarrhea and other symptoms. Therefore, anyone who eats foods rich in protein should not eat persimmons immediately.

Not suitable for eating with kelp.

Kelp and persimmon with a lot of tannic acid can be eaten together. Calcium ions in kelp can combine with tannic acid in persimmon and other fruits to form insoluble conjugates, which affect the digestion and absorption of some nutrients and lead to gastrointestinal discomfort. Therefore, kelp is not suitable for eating with persimmon and other fruits.

Not suitable for eating with sweet potatoes.

The fermented products of sweet potato in the stomach can precipitate tannin and cellulose in persimmon rapidly, which affects the normal function of the stomach and may lead to intestinal obstruction.

It is not advisable to eat on an empty stomach.

When you are hungry, your stomach acid concentration is high, while persimmon contains a lot of tannins, gums and soluble astringents. If you encounter high concentration of gastric acid, stones may form. If stones become larger, it will block pylorus, increase gastric pressure, cause bloating and stomachache, and even cause symptoms such as gastrolith, gastric ulcer, gastrorrhagia and gastric perforation in severe cases.
