Ounce for ounce, game meats like elk, venison, and emu pack the most protein of any fresh meat, delivering 26 to 28 grams of protein per 100 grams when cooked. Among everyday options you’ll find at any grocery store, chicken breast and turkey breast are nearly tied at 24 grams per 3-ounce serving, with lean beef close behind. But the real answer depends on whether you’re comparing fresh cuts, dried meats, or seafood, and whether you care about protein per calorie or protein per serving.
Game Meats Lead the Pack
If pure protein density is what you’re after, game meats consistently outperform conventional options. USDA data on cooked meats per 100 grams tells the story clearly:
- Emu: 28.4g protein
- Elk: 26.6g protein
- Venison (deer): 26.5g protein
- Ostrich: 26.2g protein
- Bison: 25.4g protein
- Beef: 23.8g protein
Emu tops the list at nearly 5 grams more protein per 100 grams than conventional beef. Elk and venison aren’t far behind. These meats are also leaner than beef, which means a higher percentage of their calories come from protein rather than fat. The tradeoff is availability and price. Bison is increasingly easy to find at supermarkets, while emu and ostrich remain specialty items.
Chicken and Turkey: The Everyday Winners
For most people, the practical answer to “what meat has the most protein” is boneless, skinless chicken breast or turkey breast. Both deliver 24 grams of protein in a standard 3-ounce cooked serving (about the size of a deck of cards). That works out to roughly 29 grams per 100 grams, which actually rivals game meats when you compare equivalent portions.
The key is sticking with breast meat. Thighs, drumsticks, and wings have more fat and connective tissue, which means less protein per gram. Skin adds calories without adding meaningful protein. A roasted chicken thigh with skin has noticeably fewer grams of protein per serving than a skinless breast, even though both are “chicken.”
How Beef and Pork Compare
Beef and pork are solid protein sources, but the cut matters enormously. Lean cuts concentrate protein while fattier cuts dilute it with calories from fat. Cooked beef averages about 24 grams per 100 grams, but a lean sirloin or eye of round will land higher than a ribeye or short rib.
Pork tenderloin, the leanest pork cut, delivers 22 grams of protein per 3-ounce cooked serving. That puts it in the same range as chicken and beef. Pork chops and loin roasts are comparable. Fattier cuts like pork belly or ribs drop well below that number because so much of their weight is fat rather than muscle.
According to Johns Hopkins Medicine, beef, chicken, turkey, pork, and lamb all provide about 7 grams of protein per ounce as a general rule. That’s a useful shorthand: multiply by however many ounces you’re eating, and you have a reasonable estimate.
Fish and Seafood
Fish is sometimes overlooked in protein conversations, but certain species hold their own against any land animal. Yellowfin tuna stands out at 21 grams of protein in a 3-ounce raw portion, compared to 18 grams for wild salmon and 17 grams for farmed salmon. Once cooked, tuna’s protein density climbs further as moisture evaporates.
Shellfish like shrimp, crab, and lobster provide about 6 grams per ounce, slightly less than poultry or beef. But because shellfish is extremely low in fat, its protein-to-calorie ratio is excellent. A serving of shrimp gives you a high proportion of protein relative to total calories, which matters if you’re watching your intake closely.
Dried Meats: The Protein Density Trick
Beef jerky and similar dried meats appear to have extraordinarily high protein content, and they do, but with an important caveat. A single cup of beef jerky pieces (90 grams) contains about 30 grams of protein. Per ounce, jerky delivers 10 to 15 grams of protein, roughly double what you’d get from the same weight of fresh cooked meat.
This isn’t because jerky contains more protein than a steak. The total protein in a piece of meat stays the same before and after drying. What changes is concentration. Removing water (meat typically loses about 25% of its weight during cooking alone, and much more during full dehydration) leaves behind a denser product where protein and fat make up a larger share of every bite. If you’re looking for the most compact, portable protein source, jerky is hard to beat. Just watch the sodium, which is typically high in cured and dried meats.
Why the Cut Matters More Than the Animal
The difference in protein between a lean chicken breast and a lean beef sirloin is small, maybe a gram or two per ounce. The difference between a lean cut and a fatty cut of the same animal is much larger. A well-marbled ribeye has significantly more fat per gram than a flank steak, and fat displaces protein in the overall weight. The same principle applies to ground meat: 93% lean ground turkey or beef packs more protein per serving than 80% lean versions, because less of the weight is fat.
When choosing meat for protein, the leanest cuts within any category will always give you the most protein per gram. Breasts over thighs. Tenderloin over belly. Sirloin over chuck. Round over ribeye.
Cooked vs. Raw Numbers
You’ll see different protein numbers depending on whether a source is listing raw or cooked values, and it’s worth understanding why. Cooking drives off water, typically reducing a piece of meat’s weight by about 25%. The protein itself doesn’t change, but because the meat now weighs less, the protein per 100 grams goes up. Raw beef contains about 18.7 grams of protein per 100 grams. Cooked, that same beef reads 23.8 grams per 100 grams.
This means you’re not actually getting more protein by cooking your meat longer. You’re just concentrating what’s already there into a smaller, denser package. When tracking protein intake, the simplest approach is to weigh meat after cooking and use cooked nutrition values, or weigh it raw and use raw values. Mixing the two will throw your numbers off.
Quick Reference by Serving
For a standard 3-ounce cooked serving, here’s what to expect:
- Chicken breast (skinless): 24g
- Turkey breast (skinless): 24g
- Lean beef: 21–24g
- Pork tenderloin: 22g
- Bison: 22g
- Elk or venison: 23g
- Yellowfin tuna: 21g (raw), higher cooked
- Wild salmon: 18g (raw)
- Shrimp/crab/lobster: 18g
The differences between most lean meats in a normal serving are modest. If you’re eating a variety of lean protein sources, you’re getting roughly 20 to 24 grams per 3-ounce portion regardless of the animal. Where it starts to matter is when you’re eating multiple servings per day and those small per-serving differences add up, or when you’re choosing between lean and fatty cuts of the same meat.
