An apple a day keeps the doctor away. Eating apples help to treat constipation because they’re high in dietary fiber. Apple with skin provides 3.3 grams of fiber per serving.
Chayote squash, also know as cho cho, is loaded with healthy fiber. According to the USDA, one cup of cooked chayote has 4.5 grams of fiber, which is 12 percent of the daily requirement. Dietary fiber from this alkaline fruit adds bulk and fluid to the stool, which keeps digestive tract healthy and prevents constipation.
