Protein is a fundamental nutrient that supports everything from muscle repair to immune function. For optimal health, experts recommend that 10% to 35% of your daily calories come from protein. If you consume around 2,000 calories per day, this translates to a range of 50 to 175 grams. To help you meet these goals, we’ve compiled a comprehensive list of the best protein sources, complete with serving sizes and practical advice.
Animal-Based Protein Sources
Animal products are often rich in high-quality protein, which your body can easily absorb and utilize. Here are some top choices to consider.
Seafood
Seafood offers lean protein along with heart-healthy omega-3 fatty acids. A standard 3-ounce serving provides substantial amounts: salmon delivers 22.5 grams, tuna has 25.5 grams, scallops offer 17.5 grams, rainbow trout contains 20 grams, shrimp provides 20.5 grams, and tilapia gives 22 grams.
Meat
Beef, pork, poultry, and lamb are all high in protein. Opt for lean cuts to minimize saturated fat, and remember to remove the skin from poultry. In a 3-ounce serving, you can expect: chicken breast with 26.5 grams, 90% lean ground beef with 22 grams, pork tenderloin with 22 grams, ground lamb with 21 grams, and ground bison with 21.5 grams.
Dairy
Dairy foods like milk, cheese, and yogurt are excellent protein sources and also supply calcium for strong bones. Common options include: skim milk with 8.5 grams per cup, low-fat plain yogurt with 9 grams in 6 ounces, cottage cheese with 14 grams in 4 ounces, and Parmesan cheese with 8 grams in 1 ounce.
Eggs
Eggs provide high-quality protein that is easily digested. Depending on size, one egg contains between 5 and 8 grams of protein.
Plant-Based Protein Sources
For those following vegetarian or vegan diets, or simply looking to diversify, plant-based proteins are a fantastic option. They are typically low in fat and high in fiber.
Legumes
Legumes are a powerhouse of plant-based protein. Per serving, you’ll find: lentils with 18 grams per cup, peas with 8.5 grams per cup, black beans with 14.5 grams per cup, chickpeas with 14.5 grams per cup, and peanuts with 7 grams per ounce.
Nuts
Nuts are rich in protein and healthy fats, but they are calorie-dense, so a typical serving is about 1 ounce. Good choices include: almonds with 6 grams, pistachios with 6 grams, Brazil nuts with 4 grams, cashews with 4.5 grams, and walnuts with 4 grams.
Soy
Soybeans, a type of legume, are high in protein and used in many plant-based foods. Common servings provide: tofu with 15 grams per serving (about 1/4 block), edamame with 18.5 grams per cup, soymilk with 7 grams per cup, and tempeh with 15.5 grams per 1/2 cup.
Seeds
Seeds may be small, but they pack a protein punch. In 1 ounce, you can get: flax seeds with 4 grams, chia seeds with 5 grams, sunflower seeds with 6 grams, and pumpkin seeds with 5.5 grams.
Whole Grains
High-fiber whole grains offer more nutrients than refined grains. Per cup, examples include: brown rice with 5.5 grams, quinoa with 8 grams, oatmeal with 11 grams, and bulgur with 6 grams.
High-Protein Fruits
While fruits are primarily known for vitamins, minerals, and antioxidants, some contain modest amounts of protein. Top picks are: avocado with 3 grams per fruit, guava with 1.5 grams per fruit, blackberries with 2 grams per cup, and apricots with 2 grams per cup.
Budget-Friendly Protein Options
High-quality meats and seafood can be expensive, but there are plenty of affordable protein sources. Consider: peanut butter, edamame, eggs, beans, lentils, canned tuna, sunflower seeds, sardines, oats, and milk.
Smart Shopping Tips for Protein
To make the healthiest and most cost-effective choices, keep these strategies in mind during your next grocery trip.
Choose Whole Foods
Packaged and prepared foods often undergo heavy processing and can be high in fat and sodium. Instead of lunch meat, opt for fresh chicken breast. Similarly, choose dried beans and cook them yourself rather than relying on canned varieties.
Look for Low Sugar and Sodium
When selecting nuts and nut butters, read labels carefully. Many products have added sugar and sodium. Aim for nut butters and whole nuts without any extra ingredients.
Try New Things
If you typically stick to chicken and eggs, consider branching out. Experiment with plant-based options or different types of seafood. This not only keeps meals interesting but also adds nutritional variety to your diet.
Look for Frozen Options
Frozen meat and fish are just as nutritious as fresh counterparts and often come at a lower price point. Pre-packaged frozen options can be a convenient and economical choice.
Buy in Bulk
Purchasing frozen meat, seafood, nuts, and beans in large quantities can lead to significant savings. Bulk buying is a smart way to stock up on protein sources without breaking the bank.
The Role of Protein at Breakfast
Research indicates that including a protein source, such as an egg or Greek yogurt, at breakfast alongside a high-fiber, whole-grain food like oatmeal can help you feel fuller for longer and reduce overall calorie intake throughout the day.
By understanding your protein needs and exploring diverse sources, you can build a balanced diet that supports your health and wellness goals. Remember, variety is key to ensuring you get all the essential nutrients your body requires.
