Persimmon has high nutritional value and is rich in sucrose, glucose, fructose, protein, carotene, vitamin C, citrulline, iodine, calcium, phosphorus and iron. The vitamin and sugar content is about1~ 2 times higher than that of ordinary fruits. If a person eats a persimmon a day, the vitamin C intake can basically meet half of the daily needs. Traditional medicine in China 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 and flat, and its nature is astringent and can be harvested. Therefore, it has the functions of strengthening the spleen and astringent intestines, treating cough and stopping bleeding. " At the same time, persimmon stem, persimmon cream and persimmon leaves can all be used as medicine. Persimmon fruit is sweet, cold and non-toxic; Persimmon stems are astringent in taste and flat in nature, and enter the lung, spleen, stomach and large intestine meridians; It has the functions of clearing away heat, eliminating dryness, moistening lung, resolving phlegm, softening hardness, quenching thirst, promoting fluid production, invigorating spleen, treating dysentery, stopping bleeding, and can relieve constipation, hemorrhoid pain or bleeding, dry cough, sore throat, hypertension and other symptoms. 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 as tea, it can also promote metabolism, lower blood pressure, increase coronary blood flow and relieve cough and phlegm. It can tonify deficiency, relieve hangover, relieve cough, promote bowel movement, remove heat, stop bleeding and satisfy hunger. Precautions Eat persimmons on an empty stomach Because persimmons contain more tannic acid and pectin, they will form lumps of different sizes under the action of gastric acid on an empty stomach. If these lumps can't reach the small intestine through pylorus, they will stay in the stomach to form stomach persimmon stones. Small stomach persimmon stones are like apricot kernels at first, but they 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. The stomach persimmon stone as big as a fist was found during surgery. If the stomach has a "bottom", the formation of stomach persimmon stone can be avoided. Persimmon skin Some people feel that chewing persimmon skin while eating persimmons is more delicious than eating persimmons 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 in persimmon when it is astringent. If it is eaten together with the skin, it is easier to form stomach persimmon stone, especially when the astringency removal process is not perfect, its skin contains more tannic acid. Taboos for eating together Don't eat with high-protein crabs, fish, shrimps and other foods. In traditional Chinese medicine, crabs and persimmons are cold foods, so they can't eat together. From the point of view of modern medicine, crabs, fish and shrimps with high protein are easily solidified into pieces under the action of tannic acid, that is, stomach persimmon stone. Persimmons can't be eaten with sweet potatoes and spinach. Other taboo persimmons contain tannin, which is easy to combine with iron, thus hindering the body's absorption of iron in food, so anemia patients should eat less. People with diabetes should not eat persimmon because it contains10.8% sugar, and most of them are simple disaccharides and monosaccharides (such as sucrose, fructose and glucose), so it is easy to be absorbed after eating, which makes blood sugar rise. For diabetics, especially those with poor blood sugar control are more harmful. People with chronic gastritis, delayed emptying, dyspepsia and other low gastric motility should not eat persimmons after subtotal gastrectomy.
