Carbohydrate counting is a method of keeping track of the number of carbohydrates you eat at each meal. Carbohydrates from your food get digested and absorbed as a sugar, known as glucose. Counting carbohydrates allows you to be aware of how food will affect your blood glucose. This is important if you need to manage your blood sugar levels.

Carbohydrate counting is particularly useful for people who take insulin shots since it allows you to balance food intake with insulin. The more carbohydrates you eat, the higher your blood sugar will be, and the more insulin you will need. Of course, always ask your doctor before adjusting insulin doses on your own.
