Abstract: The prevalence of type 2 diabetes (T2DM) is increasing worldwide and a disproportionate burden of this increase is borne by developing economies. It is yet to be established whether dietary strategies and interventions which have been successful in the control of T2DM in Western nations will achieve the same effect in the African setting. We studied the effect of a formulated high caloric fibre diet on the glycemic and lipid profile of tablet treated type 2 Nigerian diabetics. We assigned 52 type 2 diabetics (26 men, 26 women) to either an intervention (35) or control group (17). Each subject in the intervention group consumed a diet providing at least 40g of fibre per day while subjects in the control group were fed a regular diet. The effect of both diets on glucose and lipid profile was then tested at 4 and 8 weeks. One way repeated measures analysis of variance for the follow up period showed a significant lowering of waist circumference p = 0.002, Fasting Blood Glucose, 2hr post prandial glucose, Total Cholesterol, Triglyceride, and LDL-C (p = 0.000 in all cases) by the third visit in the intervention group. At the end of the third visit, the mean FBG decreased by 4.9 ± 2.7mmol/l 95% CI -5.8 to -3.9 in the intervention group and by 3 ± 2.8mmol/l 95% CI -4.5 to -1.5 in the control group p = 0.02. 23 (65.7%) intervention group subjects had attained FBG levels = 7.0 mmol/l by the third visit. None of the control subjects had their FBG lowered below 7.0 mmol/l by the third visit. Plasma glucose concentration 2hr after meal, plasma TC, TG and LDL-C decreased significantly more in the intervention group than among those in the control group. By the second visit, all the patients in the control group had their Glibenclamide increased to10mg or their Chlorpropamide to between 375 and 500mg per day while 29 (82.9%) persons in the intervention group had their drugs increased in a similar fashion. By the third visit, 8(47.1%) control subjects had a further increase in the dose of their sulphonylurea while all but 2 (5.7%) patients in the subject group had achieved normoglycemia. Consumption of a high fibre diet provided mainly through soup thickeners and vegetables by newly diagnosed Type 2 diabetic patients being treated with oral hypoglycaemic agents resulted in early attainment of normoglycaemia and improved glycemic and lipid profile compared with a conventional diet. These findings underscore the need for our dietary guidelines to include specific recommendations on increased utilization of dietary fibre.
