Two days ago, my daughter-in-law colleague was invited to dinner at home to celebrate moving to a new house, and when I came back, I brought back a bag of dried persimmons (also called persimmons), the tree of my colleague's hometown, her colleague dried it herself, and when she came out, she had to give a copy per person, and the finishing was also very neat, and the color was also very beautiful, I ate one that night, the sweetness was really high, because the persimmon peeled and dried, so there was no astringent taste, the children at home also liked to eat, and I wanted to eat one, but I heard that the old people could not eat more persimmons when I was a child, so I didn't eat it again on the child。
But that night my stomach was a little uncomfortable, a little flatulence, I suddenly remembered that I ate persimmons at night, and said that eating persimmons would cause stones, I was still very nervous, so I immediately ate a few tablets of stomach digestion, and slowly the stomach felt gone, and then I fell asleep and broke out in a cold sweat.
It is said that everyone must have heard of the news of stomach stones caused by improper eating of persimmons, and some people lost their lives because of eating persimmons. In general, persimmons are really not a conventional food in our place, and only in our local persimmon ripe season, will be sold, ripe persimmons are golden or red, look jubilant, plus the homonym of persimmon "everything goes well", so it also means that everything goes well, everything goes well, and a few freshly picked persimmons are placed at home to look at it is also happy.
We will pick the persimmons on the tree before they are fully ripe, and then eat them when they are soft and astringent. If you wait until it is fully ripe and then pick it, it will fall to the ground and break, and secondly, when it is about to ripen, the birds will taste it first, and they will not be able to fall into the whole persimmon. Third, if you want to dry persimmons, you have to peel them, and when they are hard, they are easier to peel, and they should be picked off and dried early. Therefore, if we want to eat whole persimmons, we have to pick them before they are ten ripe on the tree.
From a medicinal point of view,Persimmon has the effect of lowering blood pressure, improving circulation, and softening blood vesselsTherefore, if patients with high blood pressure eat persimmons in moderation, it can help lower blood pressure and prevent arteriosclerotic diseases.
But in everyday life, persimmons belong to the more difficult type of fruit to digestIf you eat a lot of persimmons, it is easy to cause indigestion symptoms such as bloating and hiccupsAt the same time, if you eat more unripe persimmons, it can also cause undesirable conditions such as gastric stones, the main reason is because it contains tannic acid, and the epidermis content is the most. Tannic acid, also called tannin, is the astringency of persimmons**. In addition to persimmons, grapes, hawthorns, pomegranates and other fruits, and even the tea you drink are rich in tannic acid.
Under certain conditions, tannic acid can combine with proteins to form a precipitate with large molecules and insoluble in waterTannic proteins。When there is a lot of gastric acid in the stomach, the tannin protein and the pectin and cellulose in the food bind the persimmon peel and persimmon core together, and quickly form bezoars in the stomach, also called gastric persimmon stones, and cause stomach discomfort.
Sweet and delicious persimmons are indeed delicious, but they can indeed cause diseases if not eaten properly. At this time of year, the gastroenterology department of various hospitals often receives some patients who have stones due to eating persimmons, and even some patients have stomach stones that are too big and hard to break, and can only be removed by surgery. Gastric persimmon stone disease is a stone formation in the stomach after eating a large amount of foods with high tannin content such as persimmon and hawthorn. These fruits contain a lot of tannic acid, and under the action of gastric acid, they combine with protein to form tannic acid protein, which is insoluble in water, and then condenses with plant fibers to form bezoars.
Eat these fruits in moderation and not on an empty stomach. When eating persimmons on an empty stomach, these substances combine with stomach acid to form hard lumps of varying sizes, known as gastric stones or gastric persimmon stones, which eventually lead to digestive tract obstruction. Therefore, do not eat persimmons on an empty stomach, diabetic patients should not eat more persimmons, if there is abdominal distension and abdominal pain after eating persimmons, they should seek medical attention in time.
Persimmons can be eaten, or there are some precautions, so, does this mean that we can't eat persimmons?
The tannic acid in persimmons is not as scary as everyone fears. First of all, persimmons of different ripenesses have a large difference in tannin content, generally at 04% 4%, the difference can be up to 10 times. When the persimmon is not ripe, the tannin content is higher, especially in the outer skin layer of the pulp, and the tannin is more distributed, but the tannin is very little after ripening. To judge whether the persimmon tannin content is high, you can use the simplest method - the tongue. Generally speaking, the content of tannic acid in sweet persimmons after ripening is very small (0.less than 5%). If the persimmon is very astringent, it means that the tannin content is higher. As long as you buy regular persimmons or fully ripe persimmons, there is very little tannin, and you can eat them with confidence.
Of course, there are still some taboos for eating persimmons, and if it is a persimmon with high tannin acid, it is indeed risky. But most of the persimmons we buy now are sweet persimmons or persimmons that have been artificially deastringent, with low tannin content, and there is usually no problem, and you can still eat them with confidence.
Because children's gastrointestinal function is usually weak, eating persimmons on an empty stomach may be prone to discomfort. You should pay attention to observe the child's reaction after eating persimmons, and if you feel uncomfortable after eating, then don't give her (him) to eat.
SecondIt should not be eaten with high-protein foodsThe reason is also because of the high level of tannic acid, because tannic acid is easy to react with proteins, especially proteins, to precipitate and cause stones. Do not eat with high-protein foods such as crab, fish, shrimp, etc., nor with bananas, nor with kelp, seaweed, sweet potatoes, and spinach.
Unripe persimmons have a higher tannin contentIt is best not to eat on an empty stomachTry to wait until it is mature before giving it to your child. Do not eat raw persimmons and do not eat persimmon skins.
People with excessive gastric acid secretion and poor gastric motility, or those with stomach diseases such as gastric ulcers, try not to eat persimmons, especially those that are too astringent and unripe.
If you often feel stomach discomfort after eating persimmons, you should go to the hospital for a check-up** in time to avoid aggravation of the condition. People with heavy humidity should eat less persimmons, persimmons belong to cold food, and cold food will generally damage the spleen and stomach and aggravate moisture.
Finally, what to eat is also in moderation, the same is true for persimmons, how much "amount" should be mastered each time to eat persimmons, it is generally believed that in the case of non-fasting, it is appropriate to eat persimmons no more than 200 grams each time.
