Potato Skin
Potato skins contain "solanine," which can cause poisoning after accumulating to a certain level in the body. Because the poisoning caused by it is chronic and its symptoms are not obvious, it is often overlooked. When cooked beef with potatoes, the different concentrations of gastric acid required for digesting these two foods will prolong the time food stays in the stomach, extending the time for gastrointestinal digestion and absorption, and causing gastrointestinal discomfort.
Sweet Potato Skin
Sweet potato skins contain a high amount of alkali, and eating too much can cause gastrointestinal discomfort. Sweet potato skins that are brown or have black-brown spots are infected with "black spot bacteria," which can produce "ipomeamarone" and "ipomeamarol." When these enter the human body, they can damage the liver and cause poisoning. In mild cases of poisoning, symptoms include nausea, vomiting, and diarrhea. In severe cases, it can lead to high fever, headache, shortness of breath, convulsions, vomiting blood, coma, and even death.
Persimmon Skin
When persimmons are unripe, tannic acid is mainly found in the pulp. After ripening, tannic acid is concentrated in the skin. When tannic acid enters the human body, it reacts with proteins in food under the action of gastric acid to form precipitates—persimmon stones—which can cause various diseases.
Ginkgo Skin
The skin of the ginkgo fruit contains toxic substances such as "ginkgolic acid," "ginkgolic acid," "ginkgolic acid," and "ginkgol," which can damage the central nervous system and cause poisoning after entering the human body. Additionally, the cooked ginkgo nut should not be eaten in large quantities.
Water Chestnut Skin
Water chestnuts often grow in paddy fields, and their skins can accumulate harmful biological waste and chemicals. Additionally, water chestnut skins also contain parasites. If you eat unwashed water chestnut skins, it can lead to disease. (Source: KangQ.com)
