Protein is an important part your diet, but protein can also be the most unhealthy part of your diet, particularly if your main protein sources include bacon double cheeseburgers. Mark's Daily Apple has put together this list of bad and good protein choices:

• Instead of hamburger meat, choose grass-fed beef
• Instead of frozen chicken, choose organic chicken
• Instead of farmed salmon, choose wild salmon
• Instead of fish sticks, choose tuna
• Instead of regular eggs, choose organic DHA-enhanced eggs
• Instead of regular yogurt, choose organic or Greek yogurt
• Instead of tofu, choose Tempeh
• Instead of regular beans, choose high-protein legumes and quinoa
  
• Instead of peanuts and peanut butter, choose almonds and almond butter

What do you think about these choices? I agree with most of them, but I still think that tofu, beans and natural peanut butter can be a good addition to your diet.
