that "fiber" is chemically modified resistant starch

the FDA allows it to be called fiber, but it acts differently in the body to the soluble and insoluble fiber that most people are familiar with

IMO, it's a mistake to treat fiber as a single, fungible food component, rather than as a family of different substances with different health effects

if you're looking for "easy fiber intake", there is much more and stronger evidence for psyllium-based soluble fiber, widely available in cheap and convenient drinks like metamucil (I prefer formulations without the dye and maltodextrin, but that's getting into the weeds)
