Diets containing large amounts of dietary fibre have been shown to be beneficial in improving diabetic control. We investigated the practical aspects of administering a high-fibre diet to diabetic outpatients in Cape Town, using readily available, low-cost foodstuffs with a high dietary fibre content. Ten patients were followed up over a period of 9 months, for 3 months of which a high-fibre diet was prescribed. Although only 3 patients approached the projected dietary fibre intake, significant negative correlations were found between the mean plasma glucose changes and the dietary fibre increments (r = 0,704; P less than 0,05) and between the mean serum triglyceride changes and the dietary fibre increments (r = -0,741; P less than 0,05). These findings suggest that, were it not for poor dietary compliance, a high-fibre diet might result in significant improvement in diabetic control, and that education and motivation are of prime importance when making major changes to patients' eating habits.
已证明含有大量膳食纤维的饮食有助于改善糖尿病病情控制。我们在开普敦对糖尿病门诊患者采用易于获取、低成本且膳食纤维含量高的食品，研究了给予高纤维饮食的实际情况。10名患者接受了为期9个月的随访，其中3个月规定采用高纤维饮食。尽管只有3名患者接近预计的膳食纤维摄入量，但发现平均血糖变化与膳食纤维增加量之间存在显著负相关（r = 0.704；P < 0.05），平均血清甘油三酯变化与膳食纤维增加量之间也存在显著负相关（r = -0.741；P < 0.05）。这些发现表明，若不是饮食依从性差，高纤维饮食可能会显著改善糖尿病病情控制，并且在对患者饮食习惯进行重大改变时，教育和激励至关重要。
