Types of Burgers

A traditional ground beef burger can be a good, high-protein meal—especially if it's grass-finished beef, which we'll tell you more about in a second. Beef is one of the best sources of B12, a vitamin essential to the production of red blood cells and energy. And even though it's ranked the worst, that's largely because of how often beef burgers get totally ruined—it's hard to find burgers that don't have descriptors like "double patty," "onion shoestrings," and "crispy bacon."
