Red Apple
Apples are abundant in fiber and they have a special type of soluble fiber called pectin which has shown to improve digestion. Pectin has been found to curb diarrhea-causing bacteria and it adds bulk to stools which can alleviate diarrhea. Further, apple skin comes with a good source of insoluble fiber called cellulose which helps food pass through the digestive tract efficiently. This can ease your constipation.
