1. Bananas
The number one food on our list is a banana. Why, you ask? Bananas are rich in pectin. It is a type of soluble fiber that absorbs water from the gut thus causing the thickening of loose stool. This fruit is light and easily digestible - just what you need when your gut is disturbed.
Another reason why banana is great for diarrhea is because it is rich in potassium - a key type of electrolyte that prevents water loss or dehydration. Banana is also a part of the BRAT diet.
