Resistant starch
Dietary fiber / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Resistant starch?
Summarize this article for a 10 year old
Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals.[1][2] Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an additive in manufactured foods.[3]

Some types of resistant starch (RS1, RS2 and RS3) are fermented by the large intestinal microbiota, conferring benefits to human health through the production of short-chain fatty acids, increased bacterial mass, and promotion of butyrate-producing bacteria.[4][5]
Resistant starch has similar physiological effects as dietary fiber,[6] behaving as a mild laxative and possibly causing flatulence.[7]
