What are the benefits of protein foods in a healthy eating pattern?

---

The Protein food group is made up of a variety of protein-rich foods, including meat, poultry, fish, beans and peas, eggs and nuts and seeds. In addition to protein, these nutrient-rich foods include B vitamins, zinc, iron, vitamin E and Fiber. 

Protein foods like dried beans and peas are inexpensive sources of protein, while meat and poultry are versatile in the way they can be used. Many lean meats like beef chuck are economical while also being lower in fat. Though dairy foods have their own category, they are another source of high-quality protein. Yogurt contains all nine essential amino acids in the proportions needed for protein synthesis. 

How Much Protein Is Recommended?

*An ounce equivalent of protein is equal to 1 ounce of cooked lean beef, pork or ham; 1 ounce of chicken or turkey; one egg; 1 tablespoon of peanut or almond butter; or ¼ cup of beans.

Essential Nutrients in Protein Foods

The protein in meat, beans and nuts functions as a building block for bones, muscles, cartilage, skin and blood. Protein is also the building block for enzymes and hormones. 

Other important nutrients that can be found in protein include: 

• B vitamins. The B Vitamins include niacin, thiamin, riboflavin, B6 and B12. These vitamins serve a variety of functions in the body. They help the body release energy and build tissue. Vitamin B12 is needed for healthy blood and can only be found in animal products. 
  
• Essential fatty acids. Humans must ingest alpha-linolenic acids (omega-3) and linoleic acids (omega-6) because the body needs but cannot synthesize them on its own. Omega-3 fatty acids are often deficient in the diet, but can be found in nuts, seeds and seafood.
  
• Zinc and iron. Zinc supports immune function, while iron carries oxygen to the blood. 
  
• Vitamin E. Found in nuts and seeds, vitamin E acts as an antioxidant, enhances the immune system and prevents clots from forming in the heart’s arteries.
  
• Fiber. Beans contain dietary fiber that promotes bowel regularity and a feeling of fullness.
