Fiber Basics

Dietary fiber is the part of fruits, vegetables, and grains that is *not
digested when eaten* It comes in two basic categories - soluble and
insoluble. About three-quarters of the fiber in cereal is the insoluble
type, which contributes to what is often referred to as "intestinal
regularity." Less well known is the role of soluble fiber. About one-quarter
of the total fiber in food is the soluble type. Oats, beans and other
legumes, and some fruits and vegetables are all good sources of soluble
fiber. So is psyllium, a grain found in some cereals and in certain bulk
fiber supplements.
Here are some of the benefits of consuming soluble fiber:

 a.. When eaten on a regular basis as part of a low-fat, low cholesterol
diet, soluble fiber can help lower blood cholesterol, particularly if you
have elevated cholesterol levels
 b.. Soluble fiber slows the time it takes for the stomach to empty. This
enhances your weight loss efforts by helping you feel full for a longer
period of time
 c.. Diets high in soluble fiber may help control blood sugar levels in
people with diabetes
 d.. Foods that are good sources of fiber also tend to be rich in vitamins,
minerals, and plant chemicals, such as antioxidants
