Why was fiber once thought to be useless and why is this false?
What will be an ideal response?
Fiber is the indigestible component of carbohydrates. The human digestive system cannot break down this non-starch polysaccharide to use its contents for fuel or nutrients. If we ate nothing but fiber, we could fill our stomachs but still starve. As a result, fiber was once thought useless, as waste to be removed through processing, which led to the production of food products almost devoid of fiber like white bread. We now know fiber has value. In fact, it has a number of health benefits due to its ability to lower circulating LDL levels through binding cholesterol and carrying it out of the body through the GI tract before the LDL can reach the bloodstream.
It reduces demands on the insulin system by slowing down the release of glucose from foods eaten, and prevents constipation by stimulating the movement of food through the GI tract at a steady pace. Although the evidence is inconclusive regarding whether eating a high fiber diet prevents colon cancer, it is strong regarding fiber's benefits in promoting cardiovascular health and preventing metabolic syndrome. For example, one study found that total fiber intake was associated with a 40% reduction in coronary heart disease. Many other studies established similar benefits.
