Question: how many grams of protein in one serving?
Answer: For example, in a 3.5-ounce serving, turkey breast has 30 grams of protein; pork loin, 25 grams; lean beef, 36 grams; tuna or salmon, 26 grams. And of course, the leaner the cut of any meat, the more protein and less fat you'll get in your portion. Americans generally eat more protein than their bodies need.
