摘　　要：目的对具有代表性的山西粗杂粮食品进行胰岛素指数(Insulin index,II)测定。方法 40名空腹健康志愿者分别试食含碳水化合物50g的葡萄糖粉、炒小米、煎饼等15种粗杂粮食品,于2h内不同时点分别测其胰岛素水平。结果以葡萄糖II值为100,食用粗杂粮食品后胰岛素峰值(30min)及胰岛素应答曲线下面积比显著低于葡萄糖粉(P<0.05)。结论不同来源的碳水化合物食品有不同胰岛素应答,粗杂粮食品具有吸收缓慢而持久的特点,可维持餐后血糖稳态,降低餐后胰岛素分泌,提高机体对胰岛素的敏感性。Objective To measure the insulin index of representative shanxi coarse grains food.Method Forty healthy subjects consumed 15 kinds of carbohydrate foods glucose powder,Saute millet,pancake 15 kinds of coarse grains food.In the different point of 2 hours after consumption of test materials,blood samples were taken for insulin analyses.Results The II value and the area and peak level under the insulin-response curve of coarse food grain were significantly lower than glucose powder,regarding glucose powder as 100（P0.05）.Conclusion Coarse food grain is potentially beneficial in sustaining blood glucose status and improving insulin sensitivity.
