Taboo of potatoes: avoid eating even the skin.

Potatoes contain a toxic substance called solanine, which can cause acute poisoning if ingested in large quantities. This toxic substance is mostly concentrated in the skin, and red skin or purple skin is more than yellow skin. The number of people whose skin turns blue due to light increases with the depth of color. So when eating, you must peel it, especially the green peel, because even if potatoes are peeled after being cooked, about 65,438+00% of solanine in the peel may be transferred to the pulp.

In addition, the sprouted potatoes are more toxic, and the solanine content is 100 times higher than normal, so the buds and roots must be dug out when eating, because the substance is soluble in water and should be soaked in clear water. In addition, this substance is very easy to decompose when it meets acetic acid, and it can also be detoxified when heated and cooked. Therefore, it is advisable to stew with strong fire, and adding vinegar during cooking is more conducive to the decomposition of toxic substances. In order to prevent poisoning, it is best to discard the potatoes that germinate a lot. You should go to the hospital for treatment immediately after poisoning.
