What is Carbohydrate Counting?

Carbohydrate counting is a system that is often used to help people with diabetes monitor their carbohydrate intake so that they can give themselves the correct amount of insulin or to help their oral medications work to their best efficiency. When you were first diagnosed, hopefully your physician referred you to a Registered Dietitian (RD) or Certified Diabetes Educator (CDE) to help you understand carbohydrate counting.

Why count carbs?

Each person has individual carbohydrate needs. An active teenager needs more calories and carbohydrates than a more sedentary adult. Your doctor should have given you a goal of carbohydrate exchanges per meal or per day to help guide your choices and make your insulin or medication as effective as possible.

Carbohydrates are foods that contain glucose. Glucose is important, as it is the primary energy source for our brain, as well as other bodily functions. When trying to discern how many carbohydrates are in a food, first check the serving size, then the total carbohydrates. The total carbohydrate number includes grams of sugar, added sugar, and fiber as well. If you plan to eat more or less than the stated serving size, you should adjust the amount of carbohydrates accordingly.

But what if you don’t have a nutrition label to read? Most produce does not have a label. Keep this easy-to-read list of common carbohydrates handy any time you are wondering about the content of your food! Some may vary depending on size and preparation of food.
