Protein is a macronutrient necessary for the proper growth and function of the human body. A deficiency in protein leads to muscle atrophy and impaired functioning of the human body in general. Foods high in protein per calorie include lean chicken, lean pork, fish, lean beef, tofu, beans, lentils, low-fat yogurt, milk, cheese, seeds, nuts, and eggs.
