Resistant starch (RS) increases beneficial gastro-intestinal bacterial populations simultaneously increasing short-chain fatty acids (SCFA) such as butyrate. Butyrate acts as energy source for epithelial cells of colonic mucosa which stimulates intestinal cell proliferation and has been implicated as important in reducing obesity, diabetes and cancer. The Lactobacillus spp, Bifidobacterium spp, Bacteroides thetaiotaomicron, Clostridium cluster IV and Clostridium cluster XIV are mainly involved in the production of butyrate by fermenting RS in the large intestine. With age there is a decline in these gut bacteria, but in the present study RS and diet restriction both enhanced the bacteria involved in butyrate …
