The latest developments on dietary fiber may have a major impact on many companies currently making "dietary fiber" declarations in the U.S.
The U.S. FDA released a definition for "dietary fiber", which communicates to the food industry the types of dietary fiber that can contribute to the "dietary fiber" declaration in Nutrition and Supplement Facts labels. In a 2-part definition stated in 21 CFR §101.9(c)(6)(i), the FDA defines dietary fiber as:
Currently, the FDA considers only 7 "isolated or synthetic non-digestible carbohydrates" to have demonstrated beneficial effects in humans (see part 2 of the definition above); these fibers are now listed in the regulatory definition of dietary fiber appearing in 21 CFR §101.9(c)(6)(i). For the regulatory definition of a dietary fiber to be amended so that it includes an additional "isolated or synthetic non-digestible carbohydrate", a company can either submit a citizen petition (21 CFR §10.30) or a health claim petition (21 CFR §101.70).
On November 22nd, the FDA published a "draft guidance" document to help industry understand FDA's evaluation process of citizen petitions submitted on isolated or synthetic non-digestible carbohydrates (Part 2 of the definition above). In evaluating whether beneficial physiological effects of an isolated or synthetic non-digestible carbohydrate exist, the FDA will:
As per FDA's draft guidance document and a "Questions & Answers" document, "beneficial physiological effects" include:
Effects on glycaemic index, fermentation, and changes in the microbiota are not considered to be beneficial physiological effects by the FDA.
FDA's "draft guidance" is open for comment. The deadline for comments is January 23, 2017.
Additionally, the FDA has published a "scientific review" of the evidence on the potential beneficial physiological effects of 26 other isolated or synthetic non-digestible carbohydrates. FDA is inviting interested parties to comment on the "physiological endpoints" addressed in this review and other potentially relevant physiological endpoints. Comments are due by January 9th, 2017.
We encourage stakeholders to capitalize on these comment periods since FDA's guidance on dietary fibers will ultimately dictate which ingredients can be included in the declaration of dietary fiber in the Nutrition and Supplement Facts tables.
