Foods are divided into 6 groups that vary in carbohydrate, protein, fat, & calorie content.
Each list contains foods comparable with about the same amount of carbohydrate, protein, fat, and calories as the other choices on that list .
Because foods differ, even on the same lists, each food is measured or weighed so that the amounts of carbohydrate, protein, fat, and calories are the same in each choice.
ex. 5 starches + 3 fruits + 2 dairy + 3 veggies + 4oz meat + 3 fats
