I understand that the overwhelming majority of diabetics in this country are middle-aged people with type 2 diabetes. However, I think it is important to understand that there are at least three different types of diabetes (type 1, type 2, and gestational) and probably more. The treatment (including medication and meal plan) is different for each type. So I think it is important to specify which type of diabetes you are referring to in your post.
