Insulin and Glucagon Responses to Dietary Protein in Diabetic and Nondiabetic Men
Five men with non-insulin-dependent diabetes mellitus and fourteen nondiabetic men, were given test meals with soy protein, casein or additional carbohydrate in place of protein. Blood levels of insulin, glucagon, glucose and lipids were measured at fasting, one-half hour and two hours postprandial. To all meals, the nondiabetic subjects responded with a quick rise of the insulin level which decreased at two hours. In contrast, the diabetics showed a significantly lower insulin response at one-half hour (p < 0.05), but a tendency to higher levels at two hours. The same pattern was observed in the insulin to glucagon ratio. No significant difference between the meals was found in regard to insulin or glucagon responses, suggests that a sustained, although delayed postprandial insulin response, may be a precursor to the higher cholesterol and increased risk for cardiovascular disease among diabetics.
