Carb counting is a way for those with type 1 or type 2 diabetes to better control their blood sugar levels. Carbohydrates or “carbs” for short, are one of the main nutrients along with fats, and proteins that our body needs for energy. Carb counting is keeping track of how many carbs we consume in a specific amount of time.
Why is Carb Counting Important?
In the body carbohydrates are further broken down to glucose, or sugar. Because carbs break down into sugar, carbs affect blood sugar levels. Keeping track of carbs eaten in a certain time frame can help manage blood sugar levels.
How to Count Carbs
Carbs are in most foods so it important to check nutrition labels. Nutrition labels will show the amount of carbs in grams in food.
Example
- 1 cup of cooked pasta contains about 45 grams of carbs, or 3 carb units.
- 10 crackers have 22 grams of carbs, or 1.5 carb units.
When looking at a nutrition label, it is important to read the serving size for each food.
- The serving size is listed at the top of the nutrition label.
- To accurately count carbs, it is important to have the suggested serving size.
- To count carbs using carb units, divide by the amount of carbohydrates listed on the nutrition label by the number 15. 1 carb unit is 15 grams carb.
- For example, the pasta listed above is 3 carb units because 45 divided by 15 is 3.
Foods like produce do not have nutrition labels. For example, fruits and vegetables do not come in packages. To learn the amount of carbs for these foods, research and reading will help. Here is a quick guide:

How Many Carbs Does a Person with Diabetes Need?
The Dietary Guidelines for Americans recommends that carbs make up 45-65% of daily calorie needs, but the amount of carbs a person needs depends on many factors. These factors include height, weight, physical activity and age. For persons with diabetes who take insulin, the amount of carbs also depends on insulin doses. Usually carbs consumed at each meal and snack time are consistent from day to day. To get more information on specific carbohydrate needs contact a certified diabetes educator or a Registered Dietitian to find a carb counting plan that works for you.
