"In response to postprandial rise in glucose concentration, the pancreas increases its secretion of insulin and suppresses the release of glucagons, thereby limiting hepatic glucose production and promoting the glucose uptake by muscles and fat tissues. The increased insulin level effectively deposits a large proportion of glucose into these tissues" (Sharma et al., 2008)
And also its been reported elsewhere that "in order to control glycemic and insulinaemic responses, RS must contribute at least 14% of total dietary starch intake" (Ashwar et al., 2015).
