Abstract

This study was conducted to determine the effect of different fiber content of rice on blood levels of glucose insulin and triglyceride in normal subject. Ilpum and Suwon 464, which have different fiber content were used for the test. Two types of rice containing 50 g of carbohydrate were pressure-cooked and fed to ten healthy male volunteers after an overnight fast. After a meal, the 60-min blood glucose levels of Suwon 464 and Ilpum were 90.3$\pm$4.8 mg/dL and 111.6$\pm$2.7 mg/dL, respectively (p<0.01). And the 120-min blood insulin levels of Suwon 464 and IlPum were 2.9$\pm$0.8 mg/dL and 7.7$\pm$1.6 mg/dL, respectively (P<0.05). There was no significant difference in triglyceride level between two rice varieties. The calculated glycemic index (GI) was 64.5% for Suwon 464, suggesting that Suwon 464 high in fiber can be useful in low-GI diets.

건강한 지원자를 대상으로 전기압력밥솥으로 조리한 수원464 백미와 일품종 백미를 섭취시켜 혈당과 인슐린의 반응을 비교하여 다음과 같은 결과를 얻었다. 1. 식후 60분 후에서 수원464 백미섭취군의 혈당이 일품종 백미섭취군에 비해 유의성있게 더 감소하였다(p<0.01). 2. 실험 당질에 대한 혈당반응면 적은 수원464 백미군이 일품종 백미군에 비해 유의성 있게 낮았다(p<0.05). 3. 혈청 인슐린치는 혈당반응과 유사한 패턴을 보였으며 식후 120분에서 수원464 백미군의 인슐린치가 일품종 백미군의 인슐린치 보다 유의성 있게 더 낮았다(p<0.05). 4. 일품종 백미의 혈당지수를 100%로 하였을 때 수원464 백미의 혈당지수는 64.5%로 매우 낮게 나타났다. 5. 혈중 중성지방 농도는 식후, 두군 모두에서 공복시와 차이는 나타나지 않았고 두 군간에도 유의한 차이는 없었다. 이상의 임상시험을 통하여 일품종에 비하여 식이섬유함량이 높은 수원464는 혈당지수가 매우 낮은 것으로 밝혀졌다.
