Key Takeaways
- Choose a variety of protein sources. Mix lean proteins with plant-based options for a more balanced, nutrient-rich diet.
- Opt for grilled, baked, or minimally processed foods and limit fried, high-sodium, or heavily processed protein sources.
- The healthiest protein sources are also low in saturated fat and rich in other nutrients like fiber, healthy fats, vitamins, and minerals.
Protein is essential for building muscle, supporting the immune system, and keep the body functioning properly, but the sources you choose and how you eat them matter. From lean meats to plant-based options, here are the healthiest ways to meet your protein goals while supporting heart health.1
1. Eat Lean and Skinless Poultry
Skinless chicken or turkey breast is considered a healthy source of animal protein.2 Skinless poultry is lower in saturated fat than red meat, while still being high in protein.3 Having too much saturated fat in your diet can increase your risk of high cholesterol and heart disease.4
Look for poultry that is unprocessed, lean, and has not been injected with fats or broths.3

How it is prepared matters too. Grilled or baked poultry is healthier than those battered or fried in oil. Choose seasoning that is low in salt, and sauces or condiments that are low in fat and sodium.
2. Choose Fatty Fish and Low-Mercury Seafood Options
Most fish and shellfish are also good protein options.2
For example, 4 ounces (oz) of grilled sockeye salmon provides about 30 grams (g) of protein, while being low in sodium and saturated fat.1 Fatty fish, such as salmon, tuna, and mackerel, also contain heart-healthy omega-3 fatty acids.
Look for fresh or frozen fish that has not been battered, breaded, or fried, and canned fish with little or no added sodium.
Try to include a variety of fish and seafood in your diet, such as:
- Salmon
- Sardines
- Mackerel
- Tuna
- Lobster
- Shrimp
- Cod
- Herring
Some fish and shellfish are high in mercury or other environmental contaminants, which can have negative health effects, particularly for people who are pregnant or may become pregnant, people who are nursing, and young children. Check with the latest recommendations and advisories when choosing fish to eat.6
3. Choose Lean, Unprocessed Red Meats
Red meat, such as beef, pork, veal, mutton, lamb, or goat meat, should be limited and eaten occasionally.1
Look for unprocessed, lean cuts of meat, such as:23
- Lean cuts of beef or pork
- Top sirloin
- Round
- Tenderloin
- Lean or extra-lean ground meat (no more than 15% fat)
- Cuts with visible fat trimmed off
When preparing red meat, avoid high-temperature grilling which can create compounds that are potentially carcinogenic (cancer-causing).1
Use seasonings that are low in salt and sodium, and watch for added saturated fats from things like cooking in butter or rich sauces.
4. Eat Eggs In Moderation for Added Nutrients
Eggs are a complete protein source, meaning they contain all of the essential amino acids. They also contain healthy fats, vitamins, minerals, and antioxidants.5
While eggs contain cholesterol, this isn’t a concern for most people. High blood cholesterol is more influenced by saturated fat than dietary cholesterol.7 Most people can benefit from one egg a day, but people who have heart disease or diabetes should limit eggs to two to three a week.8
If you have familial hypercholesterolemia, talk to your healthcare provider about your egg intake.7
5. Opt for Low-Fat Dairy Products
Some low-fat dairy products can be a good source of protein when eaten in moderation, such as one to two servings per day.1
In addition to protein, dairy can provide nutrients such as calcium, vitamins, and minerals.5
Look for option such as:89
- Unsweetened lower fat yogurt, particularly high-protein yogurt such as Greek
- Kefir
- Unsweetened lower fat milk
- Lower fat, lower sodium cheeses
- Low-fat cottage cheese
6. Go With Low- or No-Sodium Legumes
Plant proteins such as legumes are a great option because they are high in protein and fiber while low in saturated fat.1
Look for legumes such as:5291
- Pinto beans
- Kidney beans
- Black beans
- Chickpeas (garbanzo beans)
- Lentils
- Split peas
- Butter beans
- Adzuki beans
- Fava beans
- Pinto beans
- Green peas
- Snow peas
- Snap peas
- Peanuts
- Black-eyed peas
- White beans
If buying canned legumes, look for no sodium added options. If that isn’t available, rinse canned beans well in water to remove some of the excess sodium.8
7. Choose Raw or Dry Roasted Unsalted Nuts and Seeds
Nuts and seeds contain protein as well as healthy fats, fiber, and other beneficial nutrients.10 Choose raw or dry roasted nuts and seeds, without added oil, sugar, or salt.11
Include a variety of nuts such as:91082
- Walnuts
- Almonds
- Pistachios
- Cashews
- Pine nuts
- Brazil nuts
- Pecans
- Hazelnuts
- Nut butters
Look for a variety of seeds such as:921
- Chia
- Pumpkin
- Sunflower
- Hemp
- Sesame
- Flax
Nuts and seeds are nutritious, but energy-dense. Be mindful of portions to prevent calories adding up quickly.8
8. Use Whole Grains Instead of Refined Grains
Whole grains are higher in protein and fiber than refined grains.122 The amount and type of protein can vary by type of grain.
Cooked quinoa contains 8 g of protein per cup, and is a complete protein.5 Amaranth, farro, millet, and sorghum are also good protein sources.13
Other whole grains include:17
- Whole wheat
- Oats
- Buckwheat
- Kamut
- Whole grain rice
9. Add Certain Vegetables as a Side
While not in as high amounts as other plant-based foods, some fruits and vegetables provide a small amount of protein, such as:1
- Corn
- Broccoli
- Aparagus
- Brussels sprouts
- Artichokes
10. Eat Tofu and Other Soy Products
Soy products, such as tofu and tempeh, are good sources of protein, as well as other nutrients and antioxidants.10 Soy is a complete protein.8
Look for soy products such as:811
- Unsweetened fortified soy beverages
- Tofu
- Soybeans
- Edamame
- Soy nuts
Why is Protein Important?
Protein has many functions, including helping the body:210
- Create and repair cells
- Grow and develop in childhood and adolescence
- Support fetal development during pregnancy
- Build and repair muscle and other tissues
- Balance body fluids
- Clot blood
- Carry oxygen, vitamins, minerals, and fat throughout the body
- Fight infection
Animal vs. Plant Protein
Animal proteins, such as meat, milk, and eggs, are complete proteins. Some plant-based proteins are complete proteins, such as quinoa and soy, but many plant-based proteins are incomplete, so it is important to eat a wide variety.5
Animal sources tend to be higher in protein, but plant-based proteins often have benefits such as fiber and low levels of saturated fat.14
Research suggests there are health benefits to getting most of your proteins from a variety of plant sources, with animal sources eaten less often.1
How Much Protein Do You Need?
The amount of protein you need depends on a number of factors including age, body size, and overall caloric needs.2 The recommendation for healthy adults is to get about 10% to 35% of your daily total calories from protein.5
You may also go by body mass, consuming a daily minimum of 0.8 g of protein per kilogram (just over 7 g per 20 pounds) of body weight.5
Even with this, your protein needs may vary. Talk to your healthcare provider or registered dietitian about the amount of protein that is best for you.
