Since many people believe that fruit and vegetable peels contain a large amount of nutrients, they eat the peels when consuming any fruits or vegetables. However, the peels of some fruits and vegetables can easily cause illness or poisoning when consumed, so these peels should be avoided.
Potato Peel
Potato peels contain "solanine", which can cause poisoning when it accumulates to a certain level in the body. Because the poisoning it causes is chronic and its symptoms are not obvious, it is often overlooked.
When stewed beef with potatoes, because the two foods require different concentrations of gastric acid for digestion, it will prolong the residence time of food in the stomach and extend the time for gastrointestinal digestion and absorption, causing gastrointestinal discomfort.
Sweet Potato Peel When a persimmon is unripe, tannic acid is mainly found in the flesh. After it ripens, the tannic acid is concentrated in the peel. When tannic acid enters the human body, it reacts with proteins in food under the action of gastric acid to form a precipitate—bezoar—which can cause various diseases. Ginkgo Peel The peel 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 when they enter the human body. In addition, the cooked ginkgo nut should not be eaten in large quantities. Water Chestnut Peel Water chestnuts often grow in paddy fields, and their peels can accumulate harmful biological excretions and chemicals. In addition, water chestnut peels also contain parasites. If you eat unwashed water chestnut peels, it can lead to disease.
