Does Phase 2 starch blocker affect dietary fiber?
Asked by npakan on Dec 29, 2008 in Nutrition



If I take Phase 2 along with a high fiber cereal or a fiber supplement, will it bind to the fiber instead of carbohydrates?


Answer

Phase2® Carb Controller does not affect fiber.  Phase2® inhibits the digestive enzyme, alpha-amylase, which is responsible for the digestion of dietary starch.  Alpha-amylase specifically breaks up long chain starches, but it does not work on dietary fiber or simple sugars.  Researchers believe that Phase2® Carb Controller inactivates alpha-amylase to permit starches to pass through the intestines with less caloric absorption.
