Opening remarks: Persimmons contain many carbohydrates, but not many other nutrients. Although persimmons are delicious but they cannot be eaten, it is generally believed that it is advisable to eat persimmons no more than 200 grams each time without fasting.
There are thousands of varieties of persimmons, according to whether it can be divided into astringent persimmon and persimmon persimmon before it matures on the tree. Among them, the astringent persimmons (most of the persimmons listed on the domestic market) must be artificially removed before they can be eaten.
The material basis that causes astringency of astringent persimmon is tannic acid (also known as tannic acid). The persimmon contains a lot of carbohydrates. Each 100 grams of persimmon contains 10.8 grams, mainly sucrose, glucose and fructose. This is why everyone feels the persimmon is sweet. The other nutrients in the persimmon are few and contain only a small amount of fat, protein, calcium, phosphorus, iron, and vitamin C.
1. Can not eat persimmon on an empty stomach
Because persimmons contain more tannic acid and pectin, they will form large and small hard blocks under the action of stomach acid under fasting conditions. If these hard blocks cannot reach the small intestine through the pylorus, they will stay in the stomach and form stomach persimmons. Small stomach persimmons are initially like apricot kernels, but they will accumulate even more. If the stomach persimmon stone can not be naturally discharged, then it will cause obstruction of the digestive tract, there will be severe pain in the upper abdomen, vomiting, and even vomiting blood and other symptoms, once found in the surgery as big as the fist stomach persimmon stone. If the stomach is "bottomed", stomach persimmons can be avoided.
2. Do not eat 200 grams each time
The tannic acid in the persimmon can form compounds that cannot be absorbed by the body with calcium, zinc, magnesium, iron and other minerals in the food, so that these nutrients cannot be used. Therefore, eating more persimmons can easily lead to the lack of these minerals. Because the persimmon contains more sugar, people who eat persimmons feel fuller than those who eat the same amount of apples and pears, which can affect appetite and reduce the intake of meals. It is generally believed that in the case of non-fasting, it is appropriate to eat persimmon no more than 200 grams each time.
3. Eat after mouthwash
Persimmons are high in sugar and contain pectin. After eating persimmons, some of them remain in the mouth, especially in the teeth, and weak acidic tannins are very easy to erode the teeth and form decayed teeth, so they eat persimmons. Drink a few saliva afterwards, or gargle in time.
There are some seemingly tempting reddish persimmons on the market, but they are not sweet at all. They are probably cooked with hormones. Because it is difficult to distinguish from the outside, it is recommended that you first buy a taste, and then decide whether you need to buy more.
4. Persimmon skin can not eat
Some people feel that eating persimmons while chewing persimmon skin is more flavorful than eating persimmons. In fact, this method of eating is unscientific. Because most of the tannic acid in the persimmon is concentrated in the skin, when the persimmon is astringent, it is impossible to remove all the tannic acid. If the skin is eaten together, it will be easier to form the stomach persimmon, especially the astringent process is not perfect. At the time, its skin contained more tannic acid.
5. Avoid eating with crab, fish, shrimp
In Chinese medicine, crabs and persimmons are cold foods and therefore cannot be eaten together. From a modern medical point of view, crabs, fish, and shrimp containing high protein are easily congealed into pieces by the action of tannins, namely stomach persimmons.
Diabetics do not eat, persimmon contains 10.8% of sugar, and most of them are simple disaccharides and monosaccharides (sucrose, fructose, glucose is this type), so it is easy to absorb after eating, so that blood sugar high. For people with diabetes, especially poor blood glucose control is even more harmful.
