Protein functions as an important building block in the body. Muscles, connective tissue, and skin are all composed of proteins.
The Recommended Dietary Allowance (RDA) for protein is 0.36 grams per pound of body weight. This is equivalent to 72 grams per day for a 198-pound male and 62 grams per day for a 171-pound female.
There is evidence to suggest we should be eating more high protein foods and that ideal intake levels could be 0.50 grams per pound or greater.
These recommendations may vary based on activity level, age, and health status.
Increasing protein intake can also play a role in weight loss. Replacing carbohydrates with protein boosts the production of appetite-suppressing hormones. This leaves you feeling full for longer, reducing your calorie intake and leading to weight loss.
To meet your daily protein needs, here is a list of 23 healthy foods high in protein that you should include in your diet.
Eggs are nutritional superstars. They are one of the healthiest sources of protein we can add to our diet. Low in saturated fat, they are an excellent source of several vitamins including 35% of the recommended daily intake (RDI) of choline which is essential for brain health.
Eggs are also rich in many essential minerals including selenium, an antioxidant in the body. One large egg provides 28% of the RDI of selenium.
The protein in eggs is split between the egg whites and the yolk. It contains all of the essential amino acids needed for proper health. The majority of the vitamins and minerals are concentrated in the egg yolk.
Eat whole eggs for maximum health benefits. A large egg has a protein content of 6 grams and 78 total calories.
Chicken breast is one of the most popular foods consumed in the United States. Chicken’s popularity is largely due to its versatility and the fact that it is high in protein and low in saturated fat and cholesterol.
Baked chicken breast with the skin removed contains 24 grams of protein per three ounces serving while providing only 117 calories.
Lean beef is a nutrient-dense source of protein. To be considered lean, the USDA states that a 3-ounce serving of cooked beef must have less than 10 grams of total fat, 4.5 grams or less of saturated fat and less than 95 mg of cholesterol.
Lean ground beef includes ground round or ground sirloin. Lean steaks include skirt steak and sirloin steak.
A 3-ounce cooked sirloin steak has a protein content of 25 grams, 175 calories, and 40% of the RDI of both vitamin B12 and zinc.
Fish including salmon, tuna, sardines, and shrimp are major sources of Omega-3 fatty acids in our diet.
What is often overlooked is how many other nutrients are contained in a serving of fish. For example, salmon is one of the few food-based sources of vitamin D in our diets.
A 3-ounce serving of wild salmon that is broiled or baked contains 20 grams of protein,118 calories, and about 1 gram of Omega-3s DHA and EPA. It also provides 177% of the RDI of vitamin B12, 64% of the RDI of vitamin D, 58% of the RDI of selenium, and several other vitamins and minerals.
Cottage cheese is a fresh cheese product that is not aged. It is popular as a post-exercise recovery snack because of its mix of whey and casein, two proteins found in dairy, help repair muscle tissue, and build muscle mass.
Low-fat cottage cheese contains 12 grams of protein per half-cup serving with just 92 calories.
Cottage cheese is a high sodium food containing 15% of the RDI of sodium per half-cup serving. Look for low sodium options and be sure to stick to just one serving per day.

Like most other cheeses Parmesan cheese is high in sodium so be careful not to include too much cheese in your daily diet.
Greek yogurt is processed differently than regular yogurt. The result is a more concentrated product that is thicker with a protein content two to three times higher than regular yogurt.
A 6-ounce container of plain nonfat Greek yogurt contains 17 grams of protein, 100 calories, and 18% of the RDI of calcium which is an important nutrient for bone health. Full-fat Greek yogurt will have the same amount of protein per serving but is much higher in calories due to the increased fat content.

A 3-ounce serving of boneless pork tenderloin contains 23 grams of protein and 131 calories.
Turkey is often thought of as a Thanksgiving staple. However, turkey deserves a place in your regular rotation as a healthy low-fat protein source that is very similar to chicken breast in terms of nutritional value.
A 3-ounce serving of roasted turkey breast has a protein content of 26 grams and 125 total calories.
