When people eat some vegetables, some people say that they should be peeled, while others say that the peel is also nutritious and does not need to be removed. In fact, both of these statements make sense. Some vegetables do not need to be peeled when eaten, such as tomatoes and cucumbers, but the peels of some vegetables are poisonous and must be processed when eaten. In life, four kinds of vegetables must be peeled when eaten, and these toxic peels must not be eaten. Next, I will show you which four kinds of vegetables have poisonous peels.

Four kinds of vegetables should be peeled before eating. The peel is poisonous and should not be eaten.

1. Peel potatoes before eating

Potatoes must be removed before eating, because potato skins contain glycoalkaloids, which are toxic ingredients. After entering the human body, they will cause a variety of poisoning reactions, such as dizziness, diarrhea, etc. In addition, glycoalkaloids will accumulate in the human body. Although a small amount of potato skins will not cause poisoning, they will cause poisoning reactions over time.

2. Peel the sweet potatoes before eating

Sweet potato peel contains a large amount of alkaline components. After these alkaline components enter the human body, they will cause gastrointestinal discomfort, especially after black spots appear on the surface of the sweet potato. Its toxic components will increase and some sweet potato ketones will be produced. People will be poisoned after improper use and will have various adverse symptoms such as nausea and vomiting.

3. Ginkgo peel

Ginkgo, also known as gingko, contains a large amount of ginkgolic acid in its peel, which is also a toxic ingredient. Once it enters the human body, it will damage the human nervous system and cause poisoning. The peel must be removed when eating ginkgo.

3. Water chestnut skin

Water chestnut is an aquatic vegetable and its peel cannot be eaten because there are many harmful substances or microorganisms on its surface. These substances will endanger intestinal health after entering the human body and cause diarrhea or abdominal pain. In addition, there are some parasites in the water chestnut skin, and people are prone to parasitic diseases after eating it.
