Soluble fiber is the only known food component that will lower blood cholesterol when is added to diet.Konjac glucomannan(KGM,a high solubal fiber can help prevent sugar from rising too high after meals by keeping food in the stomach longer.Sugar is absorbed more slowly,preventing free fatty acids and triglyceridts from rising two high after meals.Free fatty acides bind to insulin receptors and prevent insulin from doing it’s job of driving sugar from the bloodstream into cells.In addition,KGM does the follwing :

• It binds to fat in the intestines, preventing some fat absorption.
• It dissolves fluids in the large intestine and forms a gel that binds with bile acids in the intestines. As a result, the liver converts more cholesterol to bile acids, and blood cholesterol levels are reduced.
• It slows digestion and the absorption of nutrients, resulting in a slow and steady release of glucose from accompanying carbohydrates.
• It soaks up excess bile acids found in the intestinal tract - the same acids that are converted into blood cholesterol.
• It delays stomach emptying, triggering satiety (a feeling of fullness)that can be helpful in people with type 2 (can not produce insulin or insulin resistant) diabetes trying to achieve weight loss goals.
