It is a type of starch that resists digestion, and passes through the large intestine to settle in the colon, where there are beneficial bacteria that feed on it, and this is similar to what happens to dietary fiber in the digestive system, and resistant starch helps slow the absorption of glucose sugar molecules into the blood, and thus reduce blood sugar. Insulin secretion, so it can be beneficial for diabetics. [10]
