FDA is proposing significant changes to nutritional labels including redefining which carbohydrates can be declared as dietary fiber. This new definition would require proof the proposed carbohydrate demonstrates physiological benefits associated with dietary fiber. Until the carbohydrate is proven to have these benefits and is accepted by the agency, it would only be listed as a carbohydrate on the nutrition label. Once recognized by FDA as a dietary fiber, the label could then be adjusted to include this carbohydrate in the declared amount of dietary fiber.
Historically, the amount of dietary fiber declared on nutritional panels was the amount that was measured via approved AOAC analytical methods (notably 985.29, 991.43, and more recently 2009.01 and 2011.25). These methods measure the amount of carbohydrates that are not digested by enzymes found in the body.
