Title: Water containing soluble fiber
Inventor: STILLMAN SUZANNE JAFFE
IPC: A23L1/308
Filed: 2001-02-22
Abstract: A water-like fluid containing safe water and a significant quantity of soluble dietary fiber. The resulting solution is generally optically clear and has physical properties similar to potable water. The fluid is intended as a replacement for bottled, or other water, as a means to ensure proper hydration. Depending on the soluble fiber used the fluid is either non-caloric or extremely low in calories. The amount of soluble fiber is adjusted to a specific amount of water so that consumption of an adequate amount of fluid ensures hydration (e.g., eight 8 oz. glasses per day) will also providing an optimal amount of dietary fiber. This is particularly valuable in stressed situations where the diet may not provide adequate fiber without supplementation. The constant metered supply of fiber provided throughout the day is preferable to, and more convenient than, "bolus" administration of fiber through laxatives, etc. Additionally, the constant presence of soluble fiber in the digestive tract provides the known beneficial effects of moderating the postprandial increase in blood glucose, modulating serum lipid levels, and suppressing appetite.
