Ladies and gentlemen, I want to know the name of a fruit. Please tell me what you know.

Persimmon Persimmon is rich in carbohydrates such as sucrose, fructose and cellulose, and also contains nutrients such as protein, calcium and phosphorus. The astringency of persimmon is caused by tannic acid (also known as tannic acid), so it is not advisable to eat more.

Traditional Chinese medicine believes that persimmon is sweet, astringent and cold, and belongs to lung meridian. Compendium of Materia Medica records that persimmon is the fruit of spleen, lung and blood. Its taste is sweet, astringent and acceptable. Therefore, it has the functions of strengthening the spleen and astringing the intestines, treating cough and stopping bleeding. " At the same time, persimmon stems, persimmon cream and persimmon leaves can all be used as medicine.

There are thousands of persimmon varieties in the world, and they can be divided into astringent persimmons and sweet persimmons according to whether they can naturally get rid of astringency before they mature on trees. Among them, astringent persimmons (most of the persimmons listed in China belong to this category) must be artificially astringent before they can be eaten. The material basis of astringency of persimmon is tannic acid (also called tannic acid). Persimmon contains a lot of carbohydrates, and every100g of persimmon contains10.8g, mainly sucrose, glucose and fructose, which is why everyone thinks persimmon is very sweet. Persimmon has few other nutrients, only a small amount of fat, protein, calcium, phosphorus, iron and vitamin C, etc. In addition, persimmon is rich in pectin, which is a kind of water-soluble dietary fiber. It has a good laxative effect and has a good effect on correcting constipation and maintaining the normal growth of intestinal flora.

Traditional Chinese medicine believes that persimmon is sweet, astringent and cold, and has the functions of clearing away heat and dampness, moistening lung and resolving phlegm, softening hardness and quenching thirst, invigorating spleen and stopping dysentery, and stopping bleeding, and can relieve constipation, hemorrhoid pain or bleeding, dry cough, sore throat and hypertension. Therefore, persimmon is a natural health food for patients with chronic bronchitis, hypertension, arteriosclerosis and internal and external hemorrhoids. If persimmon leaves are decocted or boiled into tea, it can also promote metabolism, lower blood pressure, increase coronary blood flow, relieve cough and resolve phlegm.

Although eating persimmons has many benefits, there are several points to be reminded:

You can't eat persimmons on an empty stomach because persimmons contain more tannic acid and pectin. On an empty stomach, they will form lumps of different sizes under the action of gastric acid. If these masses can't reach the small intestine through pylorus, they will stay in the stomach and form gastric persimmon stones. The persimmon stone with a small belly looks like almonds at first, but it will accumulate more and more. If the stomach persimmon stone cannot be discharged naturally, it will cause digestive tract obstruction, severe pain in the upper abdomen, vomiting and even hematemesis. A fist-sized stomach persimmon stone was found during the operation. If the stomach has a "bottom", the formation of stomach persimmon stone can be avoided.

Persimmon skin can't be eaten. Some people think that chewing persimmon skin while eating persimmon is more delicious than eating persimmon alone. In fact, this way of eating is unscientific. Because most of the tannic acid in persimmon is concentrated in the skin, it is impossible to remove all the tannic acid when persimmon is astringent. If the skin is eaten together, it is easier to form stomach persimmon stone, especially when the astringency removal process is not perfect, and its skin contains more tannic acid.

Don't eat with high-protein crab, fish, shrimp and other foods. In traditional Chinese medicine, crabs and persimmons are cold foods and cannot be eaten together. From the point of view of modern medicine, high-protein crabs, fish and shrimps are easy to solidify into blocks under the action of tannic acid, that is, stomach persimmon stone.

Diabetics should not eat persimmons, because persimmons contain 10.8% of sugar, and most of them are simple disaccharides and monosaccharides (such as sucrose, fructose and glucose), which are easily absorbed after eating, and make blood sugar rise. It is more harmful to people with diabetes, especially those with poor blood sugar control.
