The extent of carbohydrate digestion and absorption from two diets including either instant bean flakes (174 g/d) or potato flakes (102 g/d) was measured in seven ileostomy subjects during a 2-day period. Test foods contributed 40 per cent of the total dietary starch intake (160 g/d), the remainder coming from rice and white bread. Overall, 4 per cent and 0.7 per cent of the dietary starch consumed remained unabsorbed during the bean and potato periods, respectively. Between 9.0 and 10.9 per cent of dietary bean starch and less than 1.7 per cent of potato starch were not absorbed. Dietary fibre and resistant starch were completely recovered in ileostomy effluents. In separate meal tests with 40 g starch, beans gave lower blood glucose (P less than 0.05) and serum insulin (P less than 0.01) responses than potatoes. Dietary starch malabsorption from leguminous foods is less than previously estimated and does not explain the attenuated glycaemic and insulinaemic responses.
在为期2天的时间里，对7名回肠造口术患者测定了两种饮食（分别包含即食豆片（174克/天）或土豆片（102克/天））中碳水化合物的消化和吸收程度。测试食物占总膳食淀粉摄入量（160克/天）的40%，其余来自大米和白面包。总体而言，在食用豆片和土豆片期间，分别有4%和0.7%的摄入膳食淀粉未被吸收。9.0%至10.9%的膳食豆淀粉和不到1.7%的土豆淀粉未被吸收。膳食纤维和抗性淀粉在回肠造口术排泄物中被完全回收。在单独的40克淀粉餐测试中，豆类引起的血糖反应（P<0.05）和血清胰岛素反应（P<0.01）低于土豆。豆类食物中膳食淀粉的吸收不良程度低于先前估计，且无法解释血糖和胰岛素反应减弱的现象。
