Dietary fiber-rich foods will help you treat constipation, prevent colon cancer, and strengthen your digestive tract.
Studies have shown that Africans living in rural areas hardly suffer from any digestive tract diseases because their diets are mostly whole grains that are rich in fiber. 
A high fiber diet also promotes weight loss and lowers blood sugar levels. 
The recommended daily intake of fiber according to the Academy of Nutrition and dietetics is 25 grams for women and 38 grams for men. 
However, in most western cultures, adults and children get only about 10-15 grams of fiber from the western diet that is usually high in sugar and unhealthy carbs.
To correct this, start by incorporating whole grains, legumes, fruits, and vegetables into your diet.
What is dietary fiber?
Dietary fiber also called roughage or bulk is a type of carbohydrate that is not easily digested by the body.
They are two major types of fiber – soluble and insoluble fiber.
Foods rich in soluble fiber (e.g oat) digest easily in the stomach to form a gel-like bulk that helps lower cholesterol while foods rich in insoluble fiber (e.g whole wheat) add bulk to your stool and help prevent constipation.
They are both important and provide your body with the following health benefits:
- Prevents heart disease: Dietary fiber may help prevent heart disease by helping to reduce the body’s blood cholesterol absorption.
- Promotes weight loss: Foods that are high in fiber tend to be low calories. The fiber slows the speed with which food passes from the stomach to the rest of the digestive system – thus making you feel full for longer periods.
- Prevents diabetes: Because fiber slows down how quickly food is broken down, it may help control blood sugar levels for people with diabetes by reducing blood sugar levels after meals.
- Prevents constipation and colon cancer: Fiber makes bowel movements easy and helps prevent excessive straining that may cause hemorrhoids.
