Question

Quizplus · Accepted Answer

Sugary candy is high in simple carbohydrates that are quickly absorbed in the small intestine. If too much sugar is consumed and not enough digestive enzymes are available, undigested sugars can pass through the small intestine and reach the colon. In the colon, undigested sugars can attract water and cause diarrhea.
