Protein is in many of the foods that we eat every day, but for something so common, it’s often a misunderstood part of our diets. Think of protein and you might think of steak sizzling on a grill, an energy bar touting to banish fatigue, or a protein shake promising muscle growth. Yes, these foods are all packed with protein, but when it comes to making the best protein choices to keep your body and mind healthy, quality is just as important as quantity.

What is protein?

Protein is a vital nutrient required for building, maintaining, and repairing tissues, cells, and organs throughout the body. When you eat protein, it is broken down into the 20 amino acids that are the body’s basic building blocks for growth and energy. The amino acid tryptophan influences mood by producing serotonin, which can reduce symptoms of depression and anxiety and improve overall cognitive function.

Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids. However, that doesn’t mean you have to eat animal products to get the right amino acids. By eating a variety of plant-based sources of protein each day you can ensure your body gets all the essential amino acids it needs.

The health benefits of protein

Protein gives you the energy to get up and go—and keep going. While too much protein can be harmful to people with kidney disease, diabetes, and some other conditions, eating the right amount of high-quality protein:

Keeps your immune system functioning properly, maintains heart health and your respiratory system, and speeds recovery after exercise
Is vital to the growth and development of children and for maintaining health in your senior years
Can help reduce your risk for diabetes and cardiovascular disease
Can help you think clearly and may improve recall
Can improve your mood and boost your resistance to stress, anxiety, and depression
As well as being imperative to feeling healthy and energetic, protein is also important to the way you look. Eating high-quality protein can help:

Maintain healthy skin, nails, and hair
Build muscle
Maintain lean body mass while dieting
While most people eating a Western diet get sufficient quantity of protein each day, many of us are not getting the quality of protein we need.

Not all protein is the same

When choosing protein-rich foods, it’s important to look at more than just the protein content. Red meat and whole milk dairy products, for example, while rich in protein, tend to also contain saturated fat, the health consequences of which are debated in the nutrition world. For some nutrition experts, it’s the quality of the red meat and dairy that is most important:

In countries like the U.S., for example, industrially-raised animals are typically denied access to the outdoors, fed antibiotics and growth hormones, and given GMO feed grown with pesticides.
Eating organic, grass-fed red meat and dairy from animals raised in a more natural environment avoids these additives and therefore may not carry the same health risks.
High-quality vs. low-quality protein

Distinguishing between industrially raised meat and organic, grass-fed meat is only part of separating low- and high-quality sources of protein.

While some processed or lunch meats, for example, can be a good source of protein, many are loaded with salt, which can cause high blood pressure and lead to other health problems.
Processed meats have also been linked with an increased risk of cancer, likely due to the substances used in the processing of the meat.
The key to ensuring you eat sufficient high-quality protein is to include different types in your diet, rather than relying on just red or processed meat.
Other sources of high-quality protein

Fish. Most seafood is high in protein and low in saturated fat. Fish such as salmon, trout, sardines, anchovies, sablefish (black cod), and herring are also high in omega-3 fatty acids. Experts recommend eating seafood at least twice a week.
Poultry. Removing the skin from chicken and turkey can substantially reduce the saturated fat if that concerns you. In the U.S., non-organic poultry may also contain antibiotics and been raised on GMO feed grown with pesticides, so opt for organic and free-range if possible.
Dairy products. Products such as cheese, milk, and yoghurt offer lots of healthy protein. Beware of added sugar in low-fat yoghurts and flavored milk, though, and skip processed cheese that often contains non-dairy ingredients.
Beans. Beans and peas are packed full of both protein and fiber. Add them to salads, soups and stews to boost your protein intake.
Nuts and seeds. As well as being rich sources of protein, nuts and seeds are also high in fiber and “good” fats. Add to salads or keep handy for snacks.
Tofu and soy products. Non-GMO tofu and soy are excellent red meat alternatives, high in protein and low in fat. Try a “meatless Monday,” a plant-based protein sources are often less expensive than meat so it can be as good for your wallet as it is for your health.
Not a seafood fan? Make fish more palatable
If you’re not a fan of seafood, but want to include more in your diet, there are ways to make fish more palatable.

Always buy fresh fish. Some say tilapia, cod, or salmon have the least “fishy” taste.
Disguise the taste by adding a flavorful sauce. See Resources below for recipes.
Marinate fish with Creole or Cajun seasoning.
Add shell fish or white fish, such as cod or tilapia, to a curry.
Combine grilled fish with fresh salsa or your favorite chutney.
Mix canned salmon or tuna with low-fat mayonnaise and chopped onion for a tasty sandwich filling.
How to increase protein intake

To include more high-quality protein in your diet, try replacing processed carbs with high-quality protein. It can reduce your risk for heart disease and stroke, and you’ll also feel full longer, which can help you maintain a healthy weight.

Reduce the amount of processed carbohydrates you consume—from foods such as pastries, cakes, pizza, cookies and chips—and replace them with organic, grass-fed meat, fish, beans, nuts, seeds, peas, chicken, dairy, and non-GMO soy and tofu products.
Snack on nuts and seeds instead of chips, replace a baked dessert with Greek yogurt, or swap out slices of pizza for a grilled chicken breast and a side of beans.
Other ways to get more quality protein

Choose unsalted nuts and seeds, to reduce your daily sodium intake.
When shopping for canned beans, choose the low sodium versions.
Adding more protein to your diet can increase urine output, so drink plenty of water to stay hydrated.
Increasing protein can also cause calcium loss so make sure to get plenty of calcium (1,000 to 1,200 mg per day).
