Comparing Animal-Based Protein Sources
While an egg is a solid protein choice, many animal-based foods provide substantially more per serving. Lean meats, fish, and dairy products are often the first items people think of when looking to increase their protein intake, and for good reason. They offer a complete amino acid profile, crucial for muscle repair and growth.
Lean Meats
Lean meats like chicken and turkey breast are champions of high protein. A standard 3-ounce serving of cooked chicken breast can provide around 26 to 28 grams of protein, while turkey breast offers about 20 to 25 grams. Lean beef is also a strong contender, with a 3-ounce serving containing roughly 23 grams of protein. These options are not only rich in protein but also serve as excellent sources of B vitamins, iron, and zinc.
Fish and Seafood
Fish and seafood are not just packed with protein but also with heart-healthy omega-3 fatty acids. Canned light tuna and salmon are particularly protein-dense and convenient. A 3-ounce serving of canned light tuna provides around 21 grams of protein, while the same serving of wild Atlantic salmon offers nearly 17 grams. For a leaner option, shrimp delivers an impressive 25 grams of protein in a 3-ounce serving.
Dairy Products
Dairy is a versatile source of protein that extends beyond eggs. Cottage cheese, for example, is a powerhouse, delivering up to 12.9 grams of protein in just a half-cup serving. Greek yogurt is another fantastic option, offering a creamy texture and about 16 to 20 grams of protein per 5 to 7-ounce serving.
Exploring Plant-Based Alternatives
For those following vegetarian or vegan diets, or simply looking to diversify their protein sources, a wealth of plant-based foods offer more protein than a single egg.
Legumes
Legumes are nutritional powerhouses, providing not only protein but also significant amounts of fiber and minerals. One cup of cooked lentils contains an impressive 17.9 grams of protein, along with half of your daily fiber needs. Chickpeas, or garbanzo beans, offer 14.5 grams of protein per cup, making them a base for hummus and a great addition to salads. A cup of cooked black beans provides 15 grams of protein. Edamame (immature soybeans) is also notable as one of the few complete plant-based proteins, with 18.4 grams per cup.
Nuts and Seeds
Nuts and seeds are convenient and nutrient-dense options. A single ounce of shelled pumpkin seeds contains 8.5 grams of protein. For comparison, an ounce of almonds provides about 6 grams, comparable to an egg, but a single serving of pumpkin seeds easily surpasses it.
Soy Products
Soy products like tofu and tempeh are famous for being complete proteins within the plant-based world. A three-ounce serving of firm tofu contains around 9 grams of protein, while a half-cup of tempeh packs about 15 grams. These are incredibly versatile for a variety of culinary uses.

Making the Best Choice for Your Diet
When choosing protein sources, it's essential to consider your overall dietary needs, not just the protein count. A balanced diet should incorporate a variety of sources to ensure you get a broad spectrum of nutrients. If you're vegetarian or vegan, combining different plant-based proteins can help ensure you receive all essential amino acids. For example, pairing legumes with grains is a classic way to create a complete protein. For those who eat animal products, varying your choices between lean meats, fish, and dairy adds a wider array of vitamins and minerals. The key is to see eggs as one of many excellent protein options, not the only one.
Conclusion
While the egg holds a well-deserved reputation as a protein source, many other foods easily surpass its protein content per serving. From animal-based sources like chicken breast and canned tuna to plant-based powerhouses such as lentils, edamame, and Greek yogurt, the options are plentiful. Incorporating a variety of these foods into your meals will not only help you meet your daily protein goals but also ensure a more nutrient-rich and balanced diet. Consider your specific dietary needs and preferences when selecting sources to build a sustainable and healthy eating pattern.
