Why does eating persimmons on an empty stomach cause kidney stones? How to eat persimmons without developing kidney stones

October is the season for eating persimmons. Persimmons are juicy and sweet. Although they are delicious, you should not eat too much, and it is best not to eat them on an empty stomach. Eating them on an empty stomach will increase the probability of getting stones. Why is this? Is there any way to eat persimmons without getting stones?

Why does eating persimmons on an empty stomach cause stones?

Persimmon stones are called gastric persimmon stones or persimmon stones. This is mainly because the tannic acid (tannin) in persimmons combines with proteins, cellulose and other substances in food to form water-insoluble lumps of substances. If they are not eliminated from the stomach in time, they will form stones.

The more common symptoms of persimmon stones are abdominal pain, bloating, stomach pain, vomiting, and sometimes intestinal obstruction.

Sometimes stones can wear away the gastric mucosa, leading to symptoms such as ulcers, but this is relatively rare.

According to clinical observations, people who eat persimmons on an empty stomach are more likely to develop persimmon stones, but the probability itself is not high. In other words, most people who eat persimmons on an empty stomach will not have stones.

In addition, eating persimmons after a full meal may cause persimmon stones, and both fresh persimmons and persimmon cakes can cause stones.

How to eat persimmons without getting stones

The key to avoiding stones is to avoid eating astringent persimmons, because the astringency comes from tannic acid. If you encounter astringent persimmons, you can leave them alone for a while, and the tannic acid will gradually decrease through the natural ripening process.

You can use ripening methods to accelerate the ripening process, for example, put apples, bananas and persimmons in a plastic bag and seal it, and they will be ripe in a day or two.

In addition, the formation of persimmon stones is also related to the stomach's digestive ability. Gastric acid will destroy the structure of persimmon stones, but the elderly and children have weak digestive abilities and are more likely to form stones, so these people should avoid eating persimmons on an empty stomach.

There is another important point. According to doctors' observations, people who eat several persimmons at a time or eat persimmons every day for several consecutive days have a higher probability of getting persimmon stones. Therefore, you should eat persimmons in moderation and control it according to your physical condition.

How to remove the astringency of ox-heart persimmon

1. Preservative method. The preservative method is one of the simplest methods to remove the astringency of persimmons. Take appropriate amounts of methanol, ethanol, potassium permanganate, chlorothalonil and other reagents and prepare them into preservatives. Spray the preservative on the surface of persimmons. Ten kilograms of persimmons require 25-75 ml of preservative. Persimmons will gradually remove the astringency during storage, and the shelf life can reach 100 days.

2. Pounding persimmon fruit method. If there are 100 kilograms of persimmons, select 1.5 kilograms of small persimmons, pound the small fruits and put them into a water tank, add an appropriate amount of water and stir. Pour the persimmons that need to be de-astringent into the water, continue to add water until the water goes over all the persimmons, soak for two or three days and you can eat it. This de-astringent method can maintain the original flavor of the persimmons, and it is fast and efficient.

3. Mixed fruit de-astringency method. Mix the persimmons that need to be de-astringent with ripe apples, kiwis, pears, etc. and place them in a closed place and keep at room temperature. After a week, the persimmons will be de-astringent. This is because the ripe fruits will release gases such as ethylene, which can promote the enzyme activity of the astringent persimmon itself, thereby promoting respiration and achieving the purpose of de-astringency.
