    Some people think that the sweet potato skin is healthy when eaten. In fact, it often has a great impact. The sweet potato grows underground for a long time, and its skin directly contacts the soil. Many harmful substances are absorbed in the sweet potato skin. And sweet potato skin contains a lot of alkali, excessive consumption will cause gastrointestinal discomfort. Some stall owners operating roasted sweet potatoes use coke as fuel to save costs. The harmful substances such as sulfur dioxide that are generated are also easily deposited in the skin of sweet potatoes, which can cause cancer if eaten in the skin.
