Protein Sources for a Healthy Diet
The protein sources you choose can make a big difference in your long-term health – protecting your heart, supporting healthy aging, and lowering your risk for chronic disease and even certain cancers.
Diets rich in lean poultry, fish, legumes, nuts and other plant-based proteins are consistently linked with better long-term health outcomes, while higher intakes of red and processed meats are tied to greater risks.
Here we’ll explore why protein matters and share more information about the sources with the greatest health benefits.
The Role of Protein In your Body
Protein is an essential nutrient that powers nearly every process in your body. It repairs and builds tissues, provides energy when needed, carries oxygen in your blood, and supports critical systems from immunity to hormone balance. Every cell in your body contains protein, made from amino acids that allow you to grow, heal and function every day.
Beyond these vital roles, protein also helps you feel full – supporting weight management – and preserves and builds muscle strength – especially when paired with exercise.
How Much Protein Do You Need?
The National Academy of Medicine recommends about 7 grams of protein for every 20 pounds of body weight. That’s about 50 grams daily for someone who weighs 140 pounds, or 70 grams for someone at 200 pounds. Most Americans already meet this target easily. For example, a day with yogurt at breakfast, peanut butter at lunch, and chicken with rice and beans for dinner adds up to more than 80 grams of protein.
Because it’s relatively easy to get enough, the key for most people is to focus on choosing the healthiest sources.
The Protein “Package”
Every food with protein comes bundled with more than just protein – it also carries fats, sodium, fiber and minerals, all of which can make a substantial impact on your health. For example, ground beef contains a significant amount of protein, but it’s also high in saturated fat, which is linked to elevated heart disease risk. Considering the whole “package” helps you make choices that support your health in the long-run.
Complete vs. Incomplete Proteins
Animal proteins, soy (tofu, edamame) and quinoa are all “complete proteins” – meaning they contain all nine essential amino acids your body can’t get on its own. Plant-based proteins are “incomplete” but combining foods – like beans with brown rice, or peanut butter with whole wheat bread – can give you the full set. Therefore, if your diet excludes animal products, its essential to eat a variety of plant-based foods daily.
Healthy Protein Sources
Legumes: Beans, lentils and chickpeas provide protein plus fiber, potassium, and iron.
Nuts and seeds: Nuts and seeds such as almonds, cashews, walnuts, pistachios, hemp seeds, pumpkin seeds, chia seeds, flaxseeds and sunflower seeds contain protein, key nutrients and are high in unsaturated fats that support heart health.
Whole grains: Quinoa, farro, oats and barley contain more protein than refined grains, and they keep the fiber, vitamins and minerals that get stripped out of white rice and white bread.
Vegetables: Broccoli, asparagus and Brussels sprouts add a small amount of protein to your diet, while delivering fiber and antioxidants that support overall health.
Lean meats, seafood and eggs: Chicken, turkey, fish and eggs offer high-quality protein. Opt for lean and skinless cuts, and note that a serving size is typically about 3–4 ounces (roughly the size of your palm). Fatty fish like salmon and sardines also deliver omega-3’s, which support brain and heart health. Red meat and processed meats are best enjoyed in moderation, as they are linked to higher health risks.
Soy: Tofu, tempeh and edamame are plant-based complete proteins – making them excellent alternatives to meat.
Dairy: Greek yogurt and cottage cheese are rich in protein and also supply calcium and other key micronutrients. Because some dairy products can be high in saturated fat, it’s important to be mindful of portion sizes and opt for low-fat options.
Bottom Line
Where your protein comes from matters. By choosing protein sources that also provide fiber, healthy fats and essential nutrients – like beans, nuts, seeds, fish, lean poultry and eggs – you’ll give your body the best fuel for lasting health.
