What are proteins?
Protein Foods include all foods made from seafood; meat, poultry, and eggs; beans, peas, and lentils; and nuts, seeds, and soy products. Beans, peas, and lentils are also part of the Vegetable Group.
Eat a variety of protein foods to get more of the nutrients your body needs. Meat and poultry choices should be lean or low-fat, like 93% lean ground beef, pork loin, and skinless chicken breasts. Choose seafood options that are higher in healthy fatty acids (called omega-3s) and lower in methylmercury, such as salmon, anchovies, and trout. (Source: myplate.gov)
