Persimmons are considered a valuable source of vitamins and a whole range of nutrients. It seems strange even the very idea that everyone's favorite berry can carry at least some health hazard and have a negative effect on the body. Oddly enough, but recent studies by scientists were able to prove the existence of obvious risks associated with the use of persimmons. Soothing is the fact that we are not talking about all berries, but only strongly astringent, that is, not fully ripe, fruits. Their use can cause intestinal obstruction, which threatens with serious consequences, up to and including the need for surgery.
The fact is that persimmon fruits are a source of tannic acid (tannin), which provokes an astringent effect. In unripe fruits, its concentration is much higher, which creates certain risks when consumed.
Once in the stomach, tannic acid comes into contact with gastric juice. As a result of the chemical reaction of these elements, a sticky mass is formed, which envelops the food contained in it, as well as pieces of the fruit - a "stomach stone" is created. A sufficiently dense formation is able to maintain its structure and threaten health, since there is a real risk of blocking the lumen in the intestine. If a gastric stone has formed, then one of the main methods of eliminating it remains surgical removal. Only in rare cases does an independent destruction and exit from the body occur.
Given this circumstance, when choosing a product, it is important to pay attention to the level of ripeness of persimmon fruits. Special care and caution is required for people belonging to risk categories:
with a history of gastrointestinal diseases;
who have undergone surgical treatment of diseases of the stomach, intestines, as well as neighboring organs;
suffering from diseases that can provoke depression of the intestines;
having an adhesive process in the abdominal cavity, caused by concomitant pathologies, as well as surgical intervention not related to the treatment of gastrointestinal diseases.
Of course, you should not be panicked to eat persimmons, but caution will help prevent a deplorable situation. Viscous persimmon is not the most delicious and healthy berry. In most cases, it is not only not very pleasant to eat, but also difficult to swallow due to the appearance of an unpleasant and rather strong viscosity. If you bite off a large piece and chew it not well enough, you can seriously choke. This circumstance also does not contribute to obtaining benefits from the use of berries.
