Dietary fiber could be considered the sixth group of essential nutrients. It not only keeps the digestive system clean and healthy, but can help regulate blood sugar and reduce the risk of some lifestyle-related diseases. Unfortunately, most Americans do not get enough soluble or insoluble fiber in their diets. In fact, it is estimated that Americans eat 12 g of fiber on average per day, a far cry from the 20 to 30 g per day recommended by the National Cancer Institute (NCI). Dietary fiber is found in a range of plant foods. Whole grains, such as brown rice or whole wheat, legumes, vegetables and fruits all contain soluble and insoluble fiber. The two types of fiber have different effects in the body, and both are effective in satiating the appetite and reducing bacterial toxins in the digestive system. Insoluble fiber plays a role in eliminating and absorbing toxins. Soluble fiber, while it has some impact on those functions, is more responsible for stabilizing blood sugar and reducing serum cholesterol. A new soluble dietary fiber, Fibersol-2Â®, is available from Matsutani America Inc. The ingredient is a spray-dried powder produced by the pyrolysis and controlled enzymatic hydrolysis of cornstarch. This sourcing means it is Generally Recognized As Safe (GRAS) as maltodextrin, which is readily dispersible in water and carries no inherent flavor. Matsutani outlines a number of useful properties, including very low viscosity, high solubility, low hygroscopicity and clarity in solution. Because it is high in naturally occurring chemical bonds that remain undigested in the digestive tract, it can provide many physiological benefits.
