Carbohydrate homework provides professionals the basis for developing a medical nutrion care plan that has the potential to improve blood glucose control. It serves as a mechanism to assess patients' tolerance to carbohydrate and fat and the need for nutritional or pharmacological intervention in the control of type 2 diabetes. Teaching patients with type 2 diabetes carbohydrate counting based on their post-meal glucose excusions can provide increased flexability with food choices and a means for better blood glucose control.
