Four Types of Fruit and Vegetable Skins Are Toxic and Should Not Be Eaten
The debate over whether apple peels should be eaten has been ongoing, but it is certain that the peels of these four fruits and vegetables should not be eaten! They can be harmful to health.
Potato Skins
Potatoes contain glycoalkaloids, a toxic substance that is almost entirely concentrated in the potato skins, especially in the parts that have turned green or sprouted. Some people like to cook beef with potatoes in their skins, but the cooked skins still retain the glycoalkaloids. Consuming them in large quantities can cause symptoms such as vomiting, dizziness, and diarrhea.
Persimmon Skins
The skins of ripe persimmons contain large amounts of tannic acid, which is why they have a astringent taste. In the stomach acid, tannic acid reacts with the protein in food to form a precipitate, known as a persimmon stone. This substance can easily cause symptoms such as discomfort in the upper abdomen, bloating, and loss of appetite. Therefore, do not eat unpeeled persimmons, and do not eat them on an empty stomach.
Sweet Potato Skins Water Chestnut Skins Water chestnuts grow in paddy fields, and their skins absorb many harmful and toxic biological waste products, and also contain parasites. Eating raw water chestnut skins can cause symptoms such as diarrhea and vomiting. Furthermore, it should be noted that water chestnut skins contain a lot of starch, and diabetics should consume them with caution.
