Dietary resistant starch (RS) has received considerable attention as a novel method to control body weight and prevent obesity [1]. Broadly categorized, resistant starch is any starch that passes undigested and unabsorbed through the small intestine to the colon [2]. Once in the colon, RS can be readily used as substrate for microbial fermentation, resulting in the production of short chain fatty acids and other metabolites that may have beneficial metabolic properties.
