At long last, FDA has provided guidance on many dietary fibers. To be clear, the FDA announcement covers about 70–75 percent of common dietary fibers in use today, so more work needs to be done.
I say finally, because the resolution of this issue has been unnecessarily delayed by FDA for reasons that are still unclear. It is important to note, that after decades of dietary fiber not being an issue up for debate, the FDA, under pressure from the Obama White House, decided to redefine dietary fiber. The American Bakers Association (ABA) has been aggressively working to fix this situation ever since.
