Lack of advantage of high-fibre, moderate-carbohydrate diets in dogs with stabilised diabetes [section sign]

To assess the influence of high-fibre, moderate-carbohydrate diets with two levels of dietary fat, compared with a commercial diet with moderate-fibre, low-carbohydrate and higher fat, on insulin requirement, glycaemic control and lipid profile of dogs with stabilised diabetes. Twelve dogs with spontaneous diabetes mellitus were studied. Glycaemic control was evaluated by plasma fructosamine, glycosylated haemoglobin and 48-hour serial blood glucose measurements. The insulin dosage required to maintain clinical stability was also determined. Lipid profiles comprised serial measurements of plasma cholesterol, triglyceride, free glycerol and free fatty acids. Data were analysed using analysis of variance. There were no significant differences in insulin requirement or glycaemic control among diets. Weight loss occurred when the dogs were fed the high-fibre, moderate-carbohydrate, moderate-fat diet (P
