Nondigestible Carbohydrate Consumption

Nondigestible carbohydrates (NDCs) are food components, including nonstarch polysaccharides and resistant starches. Many NDCs are classified as dietary fibers by the Food and Drug Administration. Because of their beneficial effects on human health and product development, NDCs are widely used in the food supply. However, although there are intake recommendations for total dietary fiber, recommendations for individual NDCs have yet to be established. Thus, this article provides guidance for nutrition and healthcare practitioners on NDC tolerable intake levels established from a recent synthesis of human trials. This knowledge can inform therapeutic doses and help to address the fiber gap.
