FDA to Propose Acacia (Gum Arabic) as a Dietary Fiber

On December 17, 2021, the FDA announced that it intended to propose to include gum acacia in the FDA definition of dietary fiber for nutrition labeling purposes.  The 2016 final rule drew a distinction between intrinsic and intact fibers and isolated or synthetic fibers.  Isolated and synthetic fibers will not be treated as “dietary fibers” for  nutrition labeling purposes unless they have been determined by FDA to have “physiological effects that are beneficial to human health.”¹ In order to make this determination, FDA will evaluate each potential fiber to see if it: (1) lowers blood glucose, (2) lowers cholesterol levels, (3) lowers blood pressure, (4) increases in frequency of bowel movements, (5) increases mineral absorption in the intestinal tract, or (6) reduces energy intake.² FDA had rejected previous attempts to treat acacia as a dietary fiber.  Following the submission of a second citizen petition in December 2020, FDA determined the petitioner demonstrated sufficient scientific research to support the claim that gum acacia produces the necessary physiological effects based on various studies linking it to the reduction of blood glucose and insulin levels.³

FDA has now identified 18 categories of non-digestible carbohydrates that qualify for dietary fiber.  FDA identified seven (7) of these carbohydrates in the definition of “dietary fiber” in the final regulation and has since identified 11 additional non-digestible carbohydrates, including acacia, for which FDA intends to propose to add to the list of dietary fibers.⁴ FDA announced that it intends to extend enforcement discretion in regard to these eleven identified fibers⁵, which would allow manufactures to include these non-digestible carbohydrates in the dietary fiber declarations on Nutrition and Supplemental Facts labels.⁶
