Calories measure the amount of energy in food. A carbohydrate is one of three macronutrients making up those calories. You may be concerned with calorie and carbohydrate content of food if you have diabetes.

Calories are also important for the person with diabetes because eating too many calories can cause weight gain making blood sugar management more difficult.
