That's pretty funny, I was just this morning looking up Quest bars on Amazon, and the comments were all furious that they had switched the fiber source in them to soluble corn fiber
Soluble corn fiber still needs more study, but then again their previous fiber source (isomalto-oligosaccharides) seems like it was worse given what evidence does exist.
(ex https://www.amazon.com/review/R3B99075S9546R/ref=cm_cr_dp_cm...)
Maybe a good change overall, although it clearly wasn't driven by this study.
