#5. Lean ground beef
Red meats, like lean ground beef, are an excellent source of protein, so completely avoiding them because of the “red” stigma might be a mistake. Just 100 grams of lean ground beef contains upward of 27 grams of protein! Although such a serving is also high-fat (it contains 11 grams of fat and around 200-plus calories) what separates beef from its other meat competitors are all the additional vitamins and minerals it contains. Beef is teeming with vitamin B12, zinc and iron — all of which are important for muscle growth and development.
