**9. Exchange lists for diabetes**

The exchange system sorts foods into groups by their proportions of carbohydrate, fat, and protein. Each food list comprises foods grouped together because they have similar nutrient content and serving sizes. Then any food on a list can be "exchanged" for any other on that same list. Foods on the Starch list, Fruits list, Milk list, and Sweets, Desserts, and Other Carbohydrates list are similar because they contain 12 to 15 grams of carbohydrate per serving.
