Apple
The amount of soluble fiber pectin in apples helps a lot for people with diarrhea and apples contain more pectin (the fiber found in fruit) than any other fruit. Pectin will be broken down in the intestines by good bacteria, forming a protective lining of the stomach, helping to soothe and prevent intestinal irritants. Besides, apples also contain natural sugar content to help replenish energy for the body during illness.
This breakdown also increases prebiotics, which increases the number of “good” gut bacteria (which attack diarrhea-causing bacteria as soon as they appear). Cooked apples are easily digestible and help the body absorb the natural nutrients in them better. Taking 1-2 apples a day will significantly help you reduce the symptoms of diarrhea.
