What is resistant starch resisting?
Resistant starch steadfastly resists its digestive fate in the small intestine, remaining untouched until it journeys to the colon where bacteria take it apart by fermentation. The products of this disassembly are short-chain fatty acids, (acetate, butyrate and propionate) instead of glucose. These fatty acids help to maintain healthy bowel function and enhance uptake of fluids and electrolytes. Butyrate and propionate feed both the cells lining the colon and the friendly resident bacteria. In this circumstance, resistant starches fit the definition of fiber along with non-starch polysaccharides; they reach the colon undigested, enhance fecal bulk and provide useful material for colon-friendly bacteria. There are different types of resistant starch that is, different ways starch can escape digestion in the small intestines: • RS1 a starch that is indigestible by virtue of the presence of whole-grain fibers. • RS2 a starch that is indigestible because some of the granules didnt swell an
