This is because bananas are tropical and subtropical fruits. In order to facilitate storage and transportation, when picking bananas, you can’t wait for it to be cooked, but when the banana peel is green, you have to take it out. Many of the bananas we eat in the north are ripened after ripening.

Tannic acid has a very strong astringent effect. If you eat more immature bananas at a time, it will not only be laxative, but will cause constipation, especially for the elderly and children with weak gastrointestinal function.
