Many foods are not suitable for eating on an empty stomach, which may cause some harm to the stomach. Persimmon is a fruit that many people have eaten, and it tastes sweet, but some elements in persimmon may cause harm to human body. There are some things to pay attention to when eating persimmon, so can persimmon be eaten on an empty stomach? What is the harm of eating persimmons on an empty stomach?

1. Is it good to eat persimmons on an empty stomach?

Eating persimmons on an empty stomach is not good. People secrete more gastric acid on an empty stomach, and their gastrointestinal function is weak. At this time, eating persimmons may cause discomfort, such as hiccups, acid reflux, nausea, vomiting, abdominal pain and diarrhea.

2. Why can't you eat on an empty stomach

Persimmon contains tannic acid, which can combine with protein under certain conditions to form a water-insoluble precipitate-tannic acid protein. When there is more stomach acid on an empty stomach, tannic acid protein reacts with pectin and cellulose in food to form stomach persimmon stone. This kind of stomach persimmon stone will cause mechanical damage to gastric mucosa, press the gastric wall, block pylorus, and further stimulate the increase of gastric acid secretion, which will lead to erosive gastritis and gastric ulcer in severe cases.

3. What kind of persimmons are good to eat

Persimmons can be divided into astringent and sweet types. Sweet persimmons are naturally astringent on trees before ripening, while astringent persimmons are suitable for eating after being picked and artificially astringent. Most persimmons in the market are astringent, and the tannic acid content is low, so just choose mature persimmons that are astringent.

4. How many persimmons can you eat a day?

According to the Dietary Guidelines for China Residents, it is recommended to eat 2-4g of fruit every day, so 1-2 persimmons of medium size (about 15-2g/persimmon) are enough every day.

5. Precautions for eating persimmons

1. People with weak gastrointestinal function should not eat astringent persimmons. Persimmons with heavy astringency have high tannic acid content, which is easy to cause adverse reactions in the stomach.

2. People with diabetes should eat persimmons carefully. Persimmons have a high sugar content, close to 2%, mostly simple disaccharides and monosaccharides, and mature persimmons are soft and rotten and can be swallowed without full chewing, so the response to raising blood sugar is higher.

3. If you feel uncomfortable after eating persimmon, you should seek medical advice promptly.

6. Dietary taboos for persimmons

1. Persimmons and crabs are alike

Persimmons are sweet, astringent and cold in nature. Eating persimmon and crab together will inhibit the secretion of digestive juice of human body and affect health. Crab is also a cold food, and it is easy to hurt the spleen and stomach when they are eaten together, so don't eat together.

2. Persimmon and sweet potato are alike

When the sugar in sweet potato is fermented in the stomach, it will increase the secretion of gastric acid, and precipitate with tannic acid and cellulose in persimmon to produce lumps, which will affect the gastrointestinal function and even lead to intestinal obstruction in severe cases.

3. Persimmons are similar to fish.

Tannic acid contained in persimmons reacts with protein and calcium salts in fish, and precipitates will appear, which will stimulate our gastrointestinal organs and easily lead to gastrointestinal diseases, such as nausea and constipation.
