Animal-Based Powerhouses: Meat, Poultry, and Seafood
For those who consume animal products, a wide array of options readily provide well over 7 grams of protein per serving. These sources are often considered 'complete' proteins, containing all nine essential amino acids necessary for the body.
Meats
Lean meats are a classic and potent source of protein. A standard 3-ounce serving is typically sufficient to exceed the 7-gram threshold.
- Chicken Breast: A 3-ounce serving of cooked chicken breast contains approximately 26.5 grams of protein. It is a versatile and lean option for various meals.
- Lean Beef: A 3-ounce serving of lean ground beef (90%) offers around 22 grams of protein. Other cuts, like beef steak, are also excellent choices.
- Pork Tenderloin: A 3-ounce serving of pork tenderloin can provide 22 grams of protein.
Fish and Seafood
Fish and seafood not only offer significant protein but also provide heart-healthy omega-3 fatty acids.
- Tuna: A 3-ounce serving of tuna offers around 25.5 grams of protein. Canned tuna is a convenient and budget-friendly option.
- Salmon: A 3-ounce serving of salmon contains roughly 22.5 grams of protein.
- Shrimp: This shellfish can provide about 20.5 grams of protein per 3-ounce serving.
Dairy and Eggs
Dairy and eggs are not only packed with protein but also with other important nutrients like calcium and vitamin B12.
- Cottage Cheese: A 4-ounce serving of cottage cheese provides around 14 grams of protein.
- Greek Yogurt: A 6-ounce container of low-fat Greek yogurt can deliver 19.9 grams of protein.
- Milk: One cup of dairy milk provides approximately 8.32 grams of protein.
- Eggs: While a single large egg has slightly less than 7 grams, a serving of two large eggs (approximately 12.2 grams) easily surpasses this target.
Plant-Based Alternatives: Legumes, Seeds, and Soy
For those following a vegetarian or vegan diet, numerous plant-based foods provide ample protein. Many require a larger serving size or combinations to create a complete amino acid profile.
Legumes
Beans and lentils are high in both protein and fiber, making them incredibly satiating.
- Lentils: One cup of cooked lentils provides about 18 grams of protein.
- Black Beans: A one-cup serving of cooked black beans offers approximately 14.5 grams of protein.
- Chickpeas: A cup of chickpeas provides around 14.5 grams of protein.
Soy Products
Soy is a complete plant-based protein source.
- Tofu: One-quarter of a block of firm tofu (approximately a half-cup serving) provides around 15 grams of protein.
- Edamame: A cup of shelled edamame can contain an impressive 18.5 grams of protein.
Nuts and Seeds
Small but mighty, many nuts and seeds are nutrient-dense and high in protein.
- Pumpkin Seeds: A quarter-cup serving of pumpkin seeds contains 8.8 grams of protein.
- Peanuts and Peanut Butter: An ounce of peanuts or a 2-tablespoon serving of peanut butter both offer around 7.2 grams of protein, hitting the target exactly.
Protein for a Healthy Lifestyle
Incorporating enough protein into your diet is essential for many bodily functions. Protein helps build and repair tissues, produces hormones and enzymes, and is vital for bone health. It also plays a key role in weight management by increasing satiety and boosting metabolism.
