Long-term effects of high-carbohydrate, high-fiber diets on glucose and lipid metabolism: a preliminary report on patients with diabetes
JW Anderson and K Ward
High-carbohydrate, high-fiber (HCF) diets have beneficial therapeutic
effects for selected patients with diabetes mellitus. We have treated 10
patients with HCF diets on a metabolic ward and followed them for an
average of 15 months while they were on maintenance diets at home. The HCF
diets containing 70 per cent of calories as carbohydrate were accompanied
by significant reductions in requirements for insulin or sulfonylureas.
Fasting plasma glucose, serum cholesterol, and triglyceride values were
significantly lower on the HCF diet than on a 43 per cent carbohydrate
diet. On the HCF diet, insulin therapy was discontinued for five patients
and sulfonylurea therapy for three. After an average of 15 months on the
maintenance diet containing 55 per cent to 60 per cent carbohydrate, seven
patients were still managed without insulin or sulfonylureas. Average
fasting plasma glucose values during maintenance diets at home were
identical to values on the HCF diets in the hospital. On the maintenance
diet, serum cholesterol values were similar to initial values but serum
triglyceride values were significantly lower than values on the 43 per cent
carbohydrate diet. These studies indicate that moderately
high-carbohydrate, high-fiber diets can be successfully followed at home
and that improvements in glucose metabolism achieved in the hospital can be
sustained outside the hospital.
