when referring to the portion size plate (found here ) the meats and proteins group shows portions of cooked meat. for example 3 ounces of cooked chicken is equal to the size of a deck of cards. that portion is the same for fish turkey and lean beef. beans are cooked portions as well. half a cup of cooked beans is equal to the size of a light bulb.
your portion size guides. are you talking cooked or raw weight of the proteins?
