The Power of Protein ^^Protein is one of the building blocks of a healthy diet to fuel and repair the body. But not every protein-rich food makes a good choice.

Medically reviewed by Niya Jones, MD, MPH

Protein is an essential element of a healthy diet. You may only think of meat when you think about protein, but this important nutrient actually comes in a number of different forms. Choosing a variety of protein-rich foods while still paying attention to your fat and cholesterol intake are the keys to healthy eating

Protein in a Healthy Diet: Why We Need Protein
Sure, protein tastes good, but why is it so good for the body? "It's an essential nutrient," says Anne Wolf, RD, registered dietitian and researcher at the University of Virginia School of Medicine. Protein serves as a critical building block for cells and tissues throughout our body. "We need it for every function in our body — for healing purposes and for building muscles," explains Wolf.
Make sure you give your body what it needs, but don't overload on protein or make it your primary food source. Remember that a healthy balance of foods is your best bet for a healthy diet.
 

Protein in a Healthy Diet: The Lowdown on Meat
As much as the body needs protein, not all protein-rich foods are good for you. You have to evaluate sources of protein for unhealthy factors, like saturated fat (unhealthy fat) and cholesterol. The saturated fat content of many types of meat is so high, you can exceed your daily fat allowance with just a few bites.
Wolf points out that skinless chicken breasts are an extremely lean source of protein. Red meat is a great source of protein, but it also contains cholesterol and can be very high in saturated fat, so you have to be careful about which meat sources you choose.
"Find lean cuts of beef and pork," says Wolf. Ask a butcher for advice on the leanest cuts and avoid meats like steak that are marbled, since that white marbling is actually fat. Processed meats, including cold cuts and hot dogs, should also be avoided because they tend to contain excess salt and fat.
Protein in a Healthy Diet: Healthiest Sources of Protein
To work protein into your diet, opt for healthier, lower-fat options. Fortunately, there are many healthy sources of protein, including beans, nuts, fish, and low-fat dairy products (these will give you needed calcium, too).
What's considered the ultimate source of protein? "We commonly use the egg as the best source of protein," says Wolf. If people are concerned about fat and cholesterol, Wolf says, they can still get their protein by just eating the egg white — the fat and cholesterol is all in the yolk.


Other healthy sources of protein include:
  • Low-fat or fat-free milk, cheese, yogurt, and other dairy products
  • Whole grains including quinoa
  • Lentils, beans like kidney and black beans, and dried peas
  • Fish
  • Soy products including tofu and soy milk
  • Protein-fortified pastas
