摘要：

The in vivo glycemic response of selected four red pigmented traditional rice cultivars was assessed by determining the glycemic index (GI) using 12 healthy human subjects. Four cultivars of brown rice were Kaluheenati, Wedaheenati, Rathkaral and Madathawalu. According to the amylose content, rice cultivars studied were classified as high amylose rice. The highest amylose and available carbohydrate contents were observed in Kaluheenati (28.5±0.5%) and Rathkaral (74.2±0.6%) respectively. The amylose content of Wedaheenati was the lowest (26.1±0.2%) while Rathkaral showed the highest (28±0.2%). The GI of rice cultivars ranged from 52.5±1.5 to 64.0±2.5%. The Wedaheenati variety exhibited the lowest GI while Madathawalu exhibited the highest GI value.
