30 years ago, there was a lot of hay made about "Olestra" (an indigestible fat substitute) and the FDA made products with it have a warning label about "loose stools", even though someone had to go absolutely buck wild to experience it. there was other stuff going on with olestra, but the association in consumers' minds of snackies and sloppy dookies killed the idea. i guess they learned their lesson, because it seems like sugar substitutes are far worse at causing blowouts than olestra was, but they are here to stay. i guess the solution was to make it so the FDA can't tell anyone what to do, re: labeling.
