15 Jun 2018 --- The US Food and Drug Administration (FDA) has issued guidance which identifies eight specific fibers that can be classified as “dietary fibers” on the upcoming Nutrition Facts Label, marking the end of two years of uncertainty for manufacturers. In 2016, the FDA initially announced a new regulatory definition for dietary fiber and stated that to be considered a source of fiber, isolated or synthetic non-digestible carbohydrates must have a demonstrated physiological health benefit.
