Fermentable fibers are the best sources of short-chain fatty acids to the colon. Resistant starch makes more butyrate than any other fiber tested, but inulin, fructo-oligosaccharide, galactooligosaccharides and pectin also make a lot of acetate. There really isn't a better source, which is why...
I will try to explain this study, as I've been following some of these researchers for a long time.
Resistant starch is fermented in the large intestine, producing the short-chain fatty acids acetate, butyrate and propionate. These researchers created an experimental type of resistant starch...
