Lean, unprocessed meats can be included in a healthy diet.

8. Lean beef
Lean beef is among the best sources of protein when consumed in moderation and is loaded with highly bioavailable iron.

9. Chicken breasts
Chicken breast is low in fat and calories but extremely high in protein. It’s a great source of many nutrients. Again, feel free to eat fattier cuts of chicken if you’re not eating many carbs.

10. Lamb
Lambs are usually grass-fed, and their meat tends to be high in omega-3 fatty acids.
