Among other benefits, dietary fiber has also been shown to actually slow the rate of digestion, which in itself can have a number of independent health implications.  For many years now, dietary fats have played an integral role in therapeutic and performance nutrition as a regulatory agent in the process of digestion.  The inhibitory effect that dietary fats have on the release of hydrochloric acid has been shown to prolong the emptying time of the stomach, therefore increasing satiety while controlling the rate at which food enters the blood stream via the liver.  As presented in the article entitled “Insulin Resistance: A New Paradigm for Medical Nutrition Therapy and Nutrition Education”, by  the American Dietetic Association in 1995 Fall Volume of SCAN’s Pulse, it was suggested that dietary fat should make up no less than 20% of the total calories at each meal in order to encourage satiety and to help manage postprandial hyperinsulinemia and associated dyslipidemia.  This concept has caused a considerable amount of controversy regarding the pros and cons of consuming dietary fats.

Although dietary fiber may not exert the same actions on the digestive process as dietary fats, fiber has been shown to slow the process of digestion and even decrease the rate of intestinal absorption therefore helping to regulate the release of insulin and its consequential effects on blood sugar.

In regards to how much fiber should be included in your diet, the recommended fiber intake per day is 20-35 grams in a ratio of 3:1 water-insoluble to water-soluble.  Furthermore, as with all other nutrients, fiber intake should be derived from whole natural foods and not synthetic products such as those found in over the counter dietary fiber supplements and laxatives.

Here is a list of some fiber rich foods to include in your daily diet: freeze-dried parsley, lima beans (dried), All Bran, red kidney beans, garbanzo beans, plain popped corn, oats, split peas, lentils, dried figs, whole wheat crackers, dried prunes, light rye toast, whole wheat, apples, baked potatoes with skin and lettuce.
