Why do many people follow this kind of diet? What the benefits they got from High-fiber diets ?

Fiber plays a very important role in a healthy diet. Fiber is also known as roughage. It is the indigestible part of plant foods that pushes through our digestive system, absorbing water along the way and easing bowel movements.

People who eat relatively high amounts of whole grains were reported to have low risks of lymphomas and cancers of the pancreas, stomach, colon, rectum, breast, uterus, mouth, throat, liver, and thyroid. A diet high in fiber is protective

against heart disease.

High-fiber diets are more likely to improve health than cause any health problems. Also useful for people who wish to lose weight. Fiber has no calories, yet provides a "full" feeling because of its water-absorbing ability. This can help treat or prevent overweight/obesity.

Below are some ways that you can do to increase the fiber in your diet:
Eat a high-fiber cereal for breakfast.
Increase fiber in meat dishes by adding pinto beans, kidney beans, black-eyed peas, bran, or oatmeal.
Eat whole grain breads
You can fruits to your diet by eating them during meals or snacks
