    Sweet potatoes grow in the ground for a long time, and the skin is in direct contact with the soil, and many harmful substances are adsorbed in the sweet potato skin. And sweet potato skin contains more alkali, too much consumption will cause gastrointestinal discomfort. In addition, some street vendors who sell roasted sweet potatoes choose coke as a fuel to save costs. The harmful substances such as sulfur dioxide generated can easily accumulate in the skin of sweet potatoes, so eating roasted sweet potatoes with skin may cause cancer.
