How to Use the Diabetes Carb Exchange Calculator
Managing blood sugar with diabetes often means keeping the carbohydrate content of each meal consistent. The American Diabetes Association's "Choose Your Foods: Food Lists for Diabetes" groups foods with similar nutrition into exchange lists, so foods can be swapped for one another in roughly equal carb "choices." This calculator takes the food group and the carb grams from a nutrition label and converts it into carb choices.
The carb amount per choice differs by food group. Starch, fruit, and milk each average about 15g of carbohydrate per exchange, while nonstarchy vegetables are much lower in carbs, so one exchange there is set at just 5g. For example, a slice of bread with about 15g of carb equals roughly 1 starch choice, while a cup of nonstarchy vegetables with 5g of carb equals 1 vegetable choice.
This calculator is a reference tool for converting a single food's carb content into choices — it does not replace a personalized meal plan. Your total daily carb targets and any insulin dosing adjustments should always be determined with your doctor or a registered dietitian, since individual needs vary widely.
