Rice is a staple carbohydrate in many countries. Previous studies have indicated that solid foods with resistant starch (RS) can attenuate glycemic response. The present study investigated the best rice for glycemic control. A single‐blind, randomized, crossover clinical trial was performed with 18 healthy subjects. Three treatments were administered at three separate study visits: short grain rice, high amylose (HA) rice 1, and HA rice 2. Postprandial capillary blood glucose, venous blood glucose and insulin measurements, and appetite visual analogue scale (VAS) surveys were done over the course of two hours. The capillary blood glucose concentrations were significantly lower for HA rice 2 compared to short grain rice at 30 min, and for HA rice 1 and HA rice 2 compared to short grain rice at 45, 60, and 120 min. Capillary blood glucose AUC was significantly lower for HA rice 1 and HA rice 2 compared to short grain rice. Venous insulin concentrations were significantly lower for HA rice 1 and HA rice 2 than short grain rice at 60 min. Subjects were significantly more hungry at 30 minutes after HA rice 1 intake than HA rice 2 intake, but there were no other significant effects in appetite ratings. The present study determined that intake of HA rice can attenuate postprandial blood glucose and insulin response in comparison to short grain rice.
