Carbohydrate counting totals the grams of carbohydrate in a meal. Each food's contribution is calculated as:
Why 15g = 1 carb exchange: The carbohydrate exchange system - widely used in diabetes meal planning - groups foods into 15g carb units called "carb exchanges" or "carb choices." This makes it easier to keep track of carb intake without a calculator on every meal.
General guidelines suggest 45-60g of carbohydrates per meal for many people with diabetes, but this varies considerably based on individual insulin sensitivity, body weight, activity level, and treatment goals. Work with your diabetes care team to set your personal carb targets.
Where to find carb counts: Check nutrition labels, use a food database app, or ask your dietitian. Whole foods like vegetables, legumes, and wholegrains also count - don't forget them.
