The possibility of modulating postprandial metabolic responses in diabetics by an increase in the amount of soluble fibre rather than by the use of the high amounts of total dietary fibre (DF), so far strongly advocated, was investigated. Soluble and insoluble DF components of common foodstuffs were analysed and the data utilized to formulate three different meals with similar quantities of available carbohydrate, protein and fat and differing only in the quantity and quality of DF: low fibre (LF), high soluble fibre (HSF) and high insoluble fibre (HIF). Ten NIDDM patients in good metabolic control received each test meal in randomized order at 2-week intervals. The postprandial blood glucose and serum insulin responses to the LF and HIF test meals were similar. The HSF meal produced significantly lower glucose (P less than 0.001) and insulin (P less than 0.05) responses, compared to either LF or HIF meals. Such results may be of relevance in the formulation of diabetic diets in order to prevent an excess of insoluble fibre, so improving patients' compliance. Fruits and vegetables may be used advantageously to increase quantities of soluble fibre, limiting excesses of legumes or guar additives.
研究了通过增加可溶性纤维量而非目前大力提倡的大量总膳食纤维(DF)来调节糖尿病患者餐后代谢反应的可能性。分析了常见食物中的可溶性和不可溶性DF成分,并利用这些数据配制了三种不同的膳食,它们的可利用碳水化合物、蛋白质和脂肪含量相似,仅DF的量和质量不同:低纤维(LF)、高可溶性纤维(HSF)和高不可溶性纤维(HIF)。十名代谢控制良好的非胰岛素依赖型糖尿病患者以随机顺序每隔两周接受一次每种测试膳食。LF和HIF测试膳食的餐后血糖和血清胰岛素反应相似。与LF或HIF膳食相比,HSF膳食产生的血糖反应(P<0.001)和胰岛素反应(P<0.05)显著更低。这些结果可能与糖尿病饮食的制定有关,以避免不可溶性纤维过量,从而提高患者的依从性。水果和蔬菜可有利地用于增加可溶性纤维的量,同时限制豆类或瓜尔胶添加剂的过量摄入。
