Long-term consumption of high-amylose starch on insulin and glucose response was investigated in 24 men: 10 control and 14 hyperinsulinemic (HI) subjects. Subjects consumed products made with standard (70% amylopectin, 30% amylose) or high-amylose (70% amylose, 30% amylopectin) cornstarch for two 14-wk periods in a crossover pattern. Starch products replaced usual starches in the self-selected diet for 10 wk followed by 4 wk of a controlled diet. After a starch-tolerance test with bread made from the starch consumed during that period, the insulin response curve area was significantly lower in all subjects after amylose consumption (P < 0.002). Glucose responses in HI and control subjects were similar and did not vary with the type of starch. Fasting triglyceride concentrations were significantly lower in subjects who consumed the high-amylose compared with the standard-starch diet throughout the study. Chronic consumption of high-amylose foods normalized the insulin response of hyperinsulinemic subjects and showed a potential benefit for diabetic subjects.
对24名男性进行了长期食用高直链淀粉对胰岛素和葡萄糖反应影响的研究：其中10名对照者和14名高胰岛素血症（HI）受试者。受试者以交叉方式在两个14周期间食用由标准（70%支链淀粉，30%直链淀粉）或高直链淀粉（70%直链淀粉，30%支链淀粉）玉米淀粉制成的产品。淀粉产品在自选饮食中替代常规淀粉10周，随后是4周的控制饮食。在用该期间食用的淀粉制成的面包进行淀粉耐量试验后，所有受试者在食用直链淀粉后胰岛素反应曲线面积显著降低（P<0.002）。HI受试者和对照者的葡萄糖反应相似，且不随淀粉类型而变化。在整个研究过程中，食用高直链淀粉的受试者空腹甘油三酯浓度显著低于食用标准淀粉饮食的受试者。长期食用高直链淀粉食物可使高胰岛素血症受试者的胰岛素反应正常化，并对糖尿病受试者显示出潜在益处。
