POSSIBILITY OF DIABETES PREVENTION BY HIGH-AMYLOSE RICE AND SUPER HARD RICE

Diabetes is one of the most devastating diseases in the world. Its prevention is very important in addition to the development of the curing technology. We started the cooperative research on low Glycemic Index (GI) rice to prevent diabetes. High-amylose rice is promising to prevent diabetes because its GI is lower than low-amylose one. Since Hoku243 presents fewer short-branched glucans and more long chains in the amylopectin starch, its starch is resistant to gelatinization and the boiled rice grains are non-sticky and brittle. The prevention of abrupt increases in postprandial blood glucose level (BGL) by feeding Sprague-Dawley (SD) rats with Hoku243 (produced by high pressure treatment (HPT) after soaking in unsalted rice koji miso) was investigated.
