Acceptability of high-fibre diets in diabetic patients

Twenty-five diabetic patients were selected from Oxford Diabetic Clinics to assess their dietary compliance (Group A). All had been taught to follow diets rich in dietary fibre in which carbohydrate provided 50% of total energy. The results were compared with those obtained previously from a similar group of patients (Group B) all of whom had been instructed to follow a diet in which carbohydrate provided 40% of total energy. The patients of Group A had a significantly greater intake of carbohydrate (45.1% vs 34.7% of total energy) and dietary fibre (33.1 g vs 18.7 g) and a lower intake of fat (33.5% vs 42.1% of total energy) than the patients of Group B. The results of dietary assessment obtained from a third group of patients (Group C), who had been advised to follow a high-fibre diet before the widespread availability of dietary teaching aids and recipe books, showed that carbohydrate and fat provided 37.5% and 41.0% of total energy, with a dietary fibre intake of 25.6 g. The results suggest that patients are willing and able to change their dietary habits towards a distribution of food constituents likely to improve diabetic control and reduce the risk of coronary heart disease when given enthusiastic instruction and support in diabetic clinics.
