The July 2006 issue of FLEX (with David Henry on the cover) has a pullout poster, with the nutritional breakdown of 200 different foods.
According to it, a 6-oz chicken breast (raw) has approximately 185 calories, 0 g carbs, 39 g protein, and 2 g fat.
I bought a food scale years ago, to help me calculate my caloric and protein intake, not to mention that my favorite issue of MuscleMag (#145) had an article on "Alternates", in which the diet section mentioned several basic foods and their nutrient values.
