What happens if you have less fiber than need?

If you have less fiber than you need, you may experience a number of health problems, including:

* Constipation. Fiber helps to bulk up stool and make it easier to pass. Without enough fiber, stool can become hard and dry, making it difficult to move through the intestines.

* Diarrhea. Fiber can also help to absorb water and electrolytes in the intestines, which can help to prevent diarrhea.

* Hemorrhoids. Hemorrhoids are swollen veins in the rectum or anus. They can be caused by straining to pass hard stools.

* Diverticular disease. Diverticular disease is a condition in which small pouches form in the colon. These pouches can become inflamed or infected, leading to pain, bleeding, and diarrhea.

* Colorectal cancer. Some studies have shown that a diet low in fiber may increase the risk of colorectal cancer.

In addition to these health problems, a diet low in fiber can also lead to weight gain and obesity. Fiber helps to fill you up and keep you feeling full, so you are less likely to overeat.

For these reasons, it is important to eat a diet rich in fiber. The recommended daily intake of fiber is 25 grams for women and 38 grams for men. You can get fiber from a variety of foods, including fruits, vegetables, whole grains, and legumes.
