A water-like fluid containing safe water and a significant quantity of solubledietary fiber. The resulting solution is generally optically clear and hasphysical properties similar to potable water. The fluid is intended as areplacement for bottled, or other water, as a means to ensure properhydration. Depending on the soluble fiber used the fluid is either non-caloricor extremely low in calories. The amount of soluble fiber is adjusted to aspecific amount of water so that consumption of an adequate amount of fluidensures hydration (e.g., eight 8 oz. glasses per day) will also providing anoptimal amount of dietary fiber. This is particularly valuable in stressedsituations where the diet may not provide adequate fiber withoutsupplementation. The constant metered supply of fiber provided throughout theday is preferable to, and more convenient than, "bolus" administration offiber through laxatives, etc. Additionally, the constant presence of solublefiber in the digestive tract provides the known beneficial effects ofmoderating the postprandial increase in blood glucose, modulating serum lipidlevels, and suppressing appetite.
