Chicken breast, turkey breast, and pork tenderloin all deliver about 24 grams of protein per 3-ounce cooked serving, making them some of the most protein-dense everyday meats you can buy. But several less common options, like elk, venison, and emu, actually edge them out. The real answer depends on whether you’re comparing raw or cooked values, lean cuts or fatty ones, and common grocery store meats or specialty game.
How Cooking Changes the Numbers
Before comparing any meats, it helps to understand one quirk of nutrition data: cooking concentrates protein. When meat loses water during cooking, the protein per 100 grams goes up even though no new protein was created. Raw red meat typically contains 20 to 25 grams of protein per 100 grams, while cooked red meat jumps to 28 to 36 grams per 100 grams. That’s purely a water loss effect. All the comparisons below use cooked values unless noted, since that reflects what actually ends up on your plate.
Poultry: Chicken and Turkey
Skinless chicken breast and skinless turkey breast are nearly identical in protein. Both provide 24 grams per 3-ounce (84-gram) serving when roasted, according to USDA data. That works out to roughly 29 grams per 100 grams cooked, placing them at the top of the common meat rankings.
The key word is “breast.” Dark meat from thighs or legs contains more fat and slightly less protein per serving. If maximizing protein per calorie is your goal, boneless skinless breast from either bird is the most efficient choice at most grocery stores.
Beef: Cut Matters More Than You Think
A braised top round steak delivers about 29 grams of protein in a 3-ounce serving, putting it right alongside chicken breast. Leaner cuts concentrate more protein per bite because there’s less fat taking up space. The leanest beef cuts, according to the Mayo Clinic, include eye of round, top round, bottom round, top sirloin, and top loin. Chuck shoulder and arm roasts also qualify as lean.
A fattier cut like ribeye or short rib still contains plenty of protein, but you get more calories from fat for the same serving size. If you’re trying to hit a protein target without overshooting your calorie budget, round and sirloin cuts are the way to go. Cooked ground beef averages around 24 grams per 100 grams, though this varies with the lean-to-fat ratio (90/10 ground beef will outperform 70/30 by a wide margin).
Pork Tenderloin: The Underrated Option
Pork often gets overlooked in protein conversations, but roasted pork tenderloin delivers 24 grams of protein per 3-ounce serving at only 120 calories. That’s the same protein as chicken breast with a comparable calorie count. Tenderloin is the leanest pork cut by far. Other cuts like pork loin chops perform well too, though fattier options like belly or ribs drop the protein-to-calorie ratio significantly.
Game Meats: The Real Protein Leaders
If you have access to wild game or specialty meats, several options outperform standard grocery store cuts. USDA research on alternate red meats found these cooked values per 100 grams:
- Emu: 28.4 g protein
- Elk: 26.6 g protein
- Venison (deer): 26.5 g protein
- Ostrich: 26.2 g protein
- Bison: 25.4 g protein
- Beef (for comparison): 23.8 g protein
Emu tops this list at over 28 grams per 100 grams cooked, roughly 4 to 5 grams more than conventional beef. Elk and venison come in close behind. These meats are also exceptionally lean, which is why their protein density is so high. The tradeoff is availability and cost. Bison has become easier to find in mainstream grocery stores, while emu and elk typically require a specialty butcher or online order.
Organ Meats Pack a Protein Punch
Organ meats are more nutrient-dense than muscle meat in several categories, and protein is one of them. Cooked beef liver provides about 29 grams of protein per 100-gram serving, rivaling chicken breast. Liver also delivers enormous amounts of B vitamins, iron, and vitamin A that muscle cuts can’t match. Heart and kidney offer similar protein levels with their own distinct nutrient profiles.
The obvious barrier is taste. Organ meats have strong, distinctive flavors that not everyone enjoys. If you can tolerate them, they’re among the most nutritionally complete protein sources available.
Dried and Processed Meats
Beef jerky has an unusually high protein density by weight because nearly all the moisture has been removed. A single ounce covers close to 10% of most adults’ daily protein needs. However, jerky and other processed meats like deli turkey or salami come with high sodium levels that offset some of the protein advantage. They work well as portable, high-protein snacks but aren’t ideal as your primary protein source throughout the day.
Protein Quality, Not Just Quantity
Grams of protein per serving only tells part of the story. How well your body can actually absorb and use that protein matters too. Scientists measure this using a score called DIAAS (Digestible Indispensable Amino Acid Score), where anything above 100 is considered excellent. Research from the University of Illinois tested a range of meat products and found that nearly all scored above 100 for adults: pork loin scored 139, medium ribeye roast hit 130, and ham reached 126. Even beef jerky scored 120.
One interesting finding: cooking temperature affects digestibility. Well-done meats consistently scored lower than medium-cooked meats. A medium ribeye roast scored 130, while the same cut cooked well-done dropped to 107. Overcooking doesn’t destroy protein, but it does make some amino acids harder for your body to access. Cooking meat to a moderate internal temperature, rather than charring it, gives you slightly better protein utilization.
Quick Comparison by the Numbers
Here’s a practical ranking of cooked meats by protein per 100 grams, combining the data above:
- Chicken breast (skinless, roasted): ~29 g
- Turkey breast (skinless, roasted): ~29 g
- Beef top round (braised): ~29 g
- Beef liver (cooked): 29 g
- Emu (cooked): 28.4 g
- Elk (cooked): 26.6 g
- Venison (cooked): 26.5 g
- Ostrich (cooked): 26.2 g
- Bison (cooked): 25.4 g
- Pork tenderloin (roasted): ~29 g per 100 g
The differences at the top are small. Chicken breast, turkey breast, lean beef cuts, pork tenderloin, and beef liver all cluster around 29 grams per 100 grams cooked. Game meats like elk and venison fall slightly below but compensate with very low fat content. For most people, the highest-protein meat is whichever lean cut you’ll actually cook and eat consistently.
