I think I was feeding the "toot" with beans and certain veggies. That stuff we're unable to digest in them turns into a picnic for the little toot makers further downstream. That's my understanding, too, that there's some enzyme required to break down an unusual shaped type of sugar or something in them, that I don't think humans make. On my current animal foods experiment that's one thing I'm enjoying the absence of, the bloating and indigestion I got from plants.
