NCT02330939

Brief Summary

The purpose of this study is to determine whether dietary fats may affect postprandial glycemic response differently according to their quality, and these effects may differ whether they are assumed in the context of meals with high or low glycemic index in patients with type 1 diabetes. This interaction between quality of fat and glycemic index of carbohydrates may have clinical implication for the calculation of prandial insulin dose in these patients.
