Eating more fiber may reduce your risk of dying from heart disease, infections and respiratory diseases, researchers from the U.S. National Cancer Institute reported.

The study also ties fiber with a lower risk of developing some cancers, diabetes and obesity, the researchers added.

In addition, fiber helps bowel movements and lowers cholesterol levels, blood sugar and blood pressure. It also promotes weight loss and reduces inflammation, they noted.

The men and women who ate the highest amount of fiber were 22 percent less likely to die from any cause compared to those who ate the lowest amount, said lead author Dr. Yikyung Park of the National Cancer Institute.

Most Americans aren't getting enough roughage in their diets. The average American eats only about 15 grams of fiber each day, much less than the current daily recommendation of 25 grams for women and 38 grams for men, or 14 grams per 1,000 calories.

The study, appearing in Monday's Archives of Internal Medicine, involved more than 388,000 adults, aged 50 to 71, who participated in a diet and health study conducted by the National Institutes of Health and AARP.
