十二名男性的饮食中含有 34% 的热量，其中 70% 是直链淀粉或支链淀粉，以确定淀粉的结构是否会影响与异常状态相关的代谢因素。以交叉设计将每种淀粉喂给受试者 5 周。当每种淀粉 4 周后给予葡萄糖耐量时，没有观察到葡萄糖或胰岛素水平的显着差异。然而，与支链淀粉相比，在每种淀粉摄入 5 周后，当含有直链淀粉的膳食时，葡萄糖和胰岛素反应显着降低。与支链淀粉后的水平相比，直链淀粉后 0.5 至 2 小时的胰岛素水平总和显着降低，但葡萄糖水平没有显着降低。在食用直链淀粉期间，平均空腹甘油三酯和胆固醇水平显着降低。长期摄入膳食直链淀粉可能有助于降低胰岛素反应，同时保持适当的糖耐量控制和低血脂水平。
Twelve men consumed a diet containing 34% of calories as 70% amylose or amylopectin starch to determine if the structure of starch could influence metabolic factors associated with abnormal states. Each starch was fed to subjects for 5 wk in a crossover design. No significant differences were observed in glucose or insulin levels when a glucose tolerance was given after 4 wk on each starch. However, glucose and insulin responses were significantly lower when a meal containing amylose compared with amylopectin was consumed after 5 wk on each starch. Summation of 0.5 through 2-h levels of insulin but not glucose were significantly lower after amylose compared with levels after amylopectin. Mean fasting triglyceride and cholesterol levels were significantly lower during the period when amylose was consumed. Long-term intake of dietary amylose may be valuable in decreasing insulin response while maintaining proper control of glucose tolerance and low levels of blood lipids.
