Fiber in Food

How much fiber should someone have each day?

The recommended daily allowance of dietary fiber for men is 30-38 grams per day and for women, 21 to 25 grams. Currently, most Americans consume only about half the recommended amount. At this level, they are missing out on fiber's potential health benefits.

How much fiber is in foods that I eat?

There are two types of fiber, soluble and insoluble.  Insoluble fibers are found in the cell walls of plants.  This type of fiber increases in size, absorbs moisture and acts as a natural laxative.  Sources of insoluble fiber include a whole grains nuts green beans, peas and the skins of fruits and vegetables.  Soluble fiber is fiber that dissolves in water. Soluble fiber will cause food absorption to slow down in the digestive system, and also stabilizes blood sugar levels.  Soluble fiber comes from oat bran, dried beans and peas, barley, carrots, apples, and most other fruits and vegetables.  The chart below shows the fiber content of some
common beans, fruits and vegetables.  (Source: Center for science in the public interest.)
