Introduction: Some people say that fruit and vegetable skins contain too much pesticide and are fatal to eat; others say that all the nutrition is in the skin, and you should eat them with the skin on. So, should you eat fruits and vegetables with their skins on or not? Below, we list 5 types of fruits and vegetables that should not be eaten with their skins.
1. Sweet Potato Skin
Sweet potato skins contain a high amount of alkali, and consuming too much can cause gastrointestinal discomfort. Sweet potato skins that are brown or have black-brown spots are infected with "black spot disease," which can produce "ipomeamarone" and "ipomeamarol." When these substances 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.
In addition, some street vendors selling roasted sweet potatoes save money by using coke as fuel. The harmful substances produced, such as sulfur dioxide, can easily accumulate in the sweet potato skin. Therefore, eating roasted sweet potatoes with their skins on poses a cancer risk.
