Give several examples of soluble and insoluble dietary fibers. List food sources of these fibers. Contrast the physical characteristics and features of these two types of fibers and their effects on gastrointestinal tract function
What will be an ideal response?
Some dietary fibers dissolve in water (soluble fibers), form gels (viscous), and are easily digested by bacteria in the colon (fermentable). Commonly found in oats, barley, legumes, and citrus fruits, soluble fibers are most often associated with protecting against heart disease and diabetes by lowering blood cholesterol and glucose levels, respectively.
Other fibers do not dissolve in water (insoluble fibers), do not form gels (non-viscous), and are less readily fermented. Found mostly in whole grains (bran) and vegetables, insoluble fibers promote bowel movements, alleviate constipation, and prevent diverticular disease.
