What Foods Are a Good Source of Protein?

The human body uses protein in every cell in the human body. Not only does it build and repair muscle, cartilage and tissue, but also manufactures hormones, enzymes, and other body chemicals. Many common foods are good sources of this important macronutrient.

Steak

• Since the Recommended Dietary Allowance advises 58 g for woman and 68 for men, a sirloin steak is a good choice for lean protein. Three ounces packs 26 g protein, 0 carbohydrates, and 10 percent of daily recommended iron.

Chicken

• One chicken breast contains approximately 40 g protein. The meat of a chicken breast is also very lean, with 5 g fat or less. Darker pieces, such as a leg, contain nearly the same amount of protein (38 g), but have a higher fat content, at roughly 12 g.

Pork

• Pork tenderloin is lean, containing only 121 calories per 100 g. It also boasts 22 g protein, 0 g of carbohydrates and only 57 mg cholesterol.

Eggs

• One large egg contains only 77 calories and 6 g of protein. Egg substitute is also a viable option, as 100 g contains 12 g protein and only 84 calories.

Mixed Nuts

• Mixed nuts are an excellent and convenient source of protein. Almonds, peanuts and pistachios contain 20 g protein a serving.
