OBJECTIVES: The goal of this study was to determine fermentation of four novel resistant starch (RS) type 4 products (RSA, B, C, and D) in Sprague Dawley male rats compared to control (CON). Assessment was by standard measures: empty cecum weight (ECW), cecal contents weight (CCW), cecal contents pH (pH), cecal contents short-chain fatty acids: acetate, propionate and butyrate, cecal contents RS (CCRS), and serum active glucagon-like peptide 1 (GLP-1). Abdominal cavity fat (abfat)/body weight was determined. METHODS: Forty weanling rats (Envigo), after a week quarantine, were randomly assigned to five groups (n = 8) for a 3-week study. Starches (Ingredion Incorporated) were RS products as 10% of weight of RS diets (equivalent to human fiber requirement) and AMIOCA® starch (100% amylopectin) comprised 53.6% weight of CON and 43.6% weight of the RS diets (RSA – RSD). The RS products varied by % purity and origin (e.g.,potato, tapioca, corn). Other ingredients (DYETS) were used (AIN-93 G). A one-way ANOVA was followed by Tukey post hoc test (P |
