Combating obesity with new Okinawan rice

In recent years, Okinawa has recorded the dubious distinction of having the highest obesity rate in Japan. Preventing obesity-related diseases is an urgent issue. A new research project has been launched to develop a new strain of rice that produces digestion-resistant starch to prevent these diseases. The project involves three activities by the medical, agricultural, and food industries: development of the new rice strain, nutritional and physiological analyses, and processing and sales.

In recent years, Okinawa has recorded the dubious distinction of having the highest obesity rate in Japan. Preventing obesity-related diseases is an urgent issue. Professor Hidetoshi Saze of the OIST Plant Epigenetics Unit is leading a new research project to develop a new strain of rice that produces digestion-resistant starch to prevent these diseases. The project, fostered by the Okinawan government, involves three activities by the medical, agricultural, and food industries: development of the new rice strain, nutritional and physiological analyses, and processing and sales.Nanshoka-Mai, or rice with digestion-resistant starch is a new breed of rice rich in starch that does not as readily break down into glucose. This rice strain was first developed by a research team at Kyushu University 30 years ago. The starch from most grains, which consist largely of an unbranched glucose polymer known as amylose, is normally broken down into glucose during the digestive process and serves as our primary energy source. However, excessive consumption of sugars (simple carbohydrates) can cause life-style-related diseases, such as obesity and diabetes. This new strain of rice is expected to serve as an alternative preventative measure. In addition to its anti-obesity effect, gathering evidence suggests that the rice with digestion-resistant starch may also provide other benefits, such as lower blood sugar levels, reduced neutral fat, and harmful cholesterol levels, and prevention of lipid accumulation in the liver.Despite its great promise, when researchers planted the original strain of resistant-starch rice in Okinawa, the yield per hectare was about half that achieved in mainland Japan.
