• Fiber is an important part of your diet, but according to bellaonline.com, studies show that only five percent of Americans eat as much fiber as they should. Adults should consume between 24 and 38 grams of fiber daily. Adequate fiber is essential for optimal health, as it aids digestion and lowers your risk for high cholesterol, heart disease, diabetes, and colon cancer. The following foods are some high-fiber foods that will help you reach the optimal fiber intake.
