Potatoes that have sprouted or have green skin are even more dangerous. At that time, the toxins produced in the potatoes are even higher. If you see this phenomenon, you should absolutely not eat both the flesh and the skin.

Tomato

Persimmon peel

Ripe, plump, red persimmons are a favorite fruit of many people.

The characteristic of this fruit is that when ripe it is very soft, peeling it is difficult. Peel it before eating, because the persimmon peel can cause stomach pain.

When tannic acid enters the stomach, it creates chemicals that combine with proteins in food, creating large and small lumps, called persimmon stones, in the stomach, leading to many dangerous health problems.
