본 연구는 정상성인에서의 오탄당 첨가 설탕의 섭취가 혈당지수와 혈당반응 미치는 영향을 분석하기 위해 수행되었다. 오탄당 감미료인 자일로바이오스(실험1)와 리보오스(실험2)의 함유비율을 달리하여 실험을 각 각 진행하였다. 실험1은 총 8주간 건강한 20대 남녀 11명을 대상으로 실험을 수행하였고, 실험2는 총 10주간 같은 조건의 남녀 14명을 대상으로 실험을 수행하였으며 실험1과 실험2 모두 무작위 배정, 공개, 2회 반복 섭취 시험으로 각각의 실험군은 4군으로 나누었으며, 섭취 후 각각의 실험의 결과는 다음과 같다.연구결과 연구대상자들의 평균나이는 각각 22.2세, 23.0세, 실험1의 남자의 평균 BMI 22.2kg/m2 실험2에서는 21.8kg/m2, 실험1의 여자의 평균 BMI는 20.4kg/m2, 실험2에서는 20.3kg/m2으로 2015한국인영양섭취기준(한국영양학회,보건복지부,식품의약품안천처 공동발간)자료에서 제시한 19~29세의 체위 기준과 비교하였을 때 남자 22.5kg/m2, 여자 21.5kg/m2 와 비슷한 수치였으며, BMI
Purpose: To compare the extent to which several different levels of pentose in sugar reduce the glycemic index (GI) and blood glucose response in healthy adults. Methods: Healthy adults (Experiment 1: six male and five female participants, n = 11, Experiment 2:eight male and six female participants, n = 14) fasted for 14~16 h after eating the same dinner. Participants in Experiment 1 were then randomized to receive glucose, sucrose containing 7% xylobiose (XBS7), sucrose containing 10% xylobiose(XBS10), or sucrose containing 14% xylobiose (XBS14) every week on the same day for 8 weeks (repeating the sample twice). Participants in experiment 2 were also treated in the same way and randomized to receive glucose, sucrose containing 5% D-ribose (DRS 7), sucrose containing 10% D-ribose(DRS10), or sucrose containing 14%D-ribose(DRS14) every week on the same day for 10 weeks (repeating the sample twice). Blood samples were collected by finger prick before and 15, 30, 45, 60, 90, and 120 min after starting to eat. Results: We observed a decreased glycemic response to sucrose containing pentose. In experiment 1 GIs for XBS7, XBS10, and XBS14 were 57.0, 53.6 and 49.7 respectively. In experiment 2 GIs for DRS5, DRB10, and DRB14 were 67.1, 47.6 and 45.6 respectively. GI values for XBS7 and DRB5 were similar to those for foods with a medium GI, and GI values for XBS10, XBS14, DRS10 and DRS14 were similar to those for foods with a low GI. The postprandial maximum blood glucose rise (Cmax) with XBS10 was the lowest among the test foods in experiment 1. The postprandial maximum blood glucose rise (Cmax) with DRB14 was the lowest among the test foods in experiment 2. Cmax values for test food were significantly lower than that for glucose. Conclusion: The results of this study suggest that sucrose containing pentose has an acute suppressive effect on GI and Cmax. In addition, Pentose active elements in sugar may be effective in preventing blood glucose spikes induced by sucrose intake.
