Chicken breast and turkey breast top the list of highest-protein meats, delivering around 30 to 31 grams of protein per 100 grams when cooked. But the answer shifts depending on whether you care about total protein per serving, protein per calorie, or protein from less common meats like game and dried options. Here’s how the most popular meats stack up.
Highest-Protein Meats per Serving
When you compare cooked meats gram for gram, poultry breast meat consistently leads among conventional options. A 100-gram serving of roasted, skinless chicken breast contains about 31 grams of protein and 140 calories. Turkey breast is nearly identical at 30 grams of protein per 100 grams, with even fewer calories at roughly 125. Both get over 70% of their calories from protein alone, which is unusually high for a whole food.
Lean beef and pork are close behind. Pork tenderloin delivers about 24 grams of protein in a 3-ounce cooked serving, and lean beef round comes in at nearly 25 grams for the same portion. Fattier cuts like 80% lean ground beef still provide solid protein (around 22 grams per 3 ounces) but pack considerably more calories, roughly 230 compared to 101 for the same amount of chicken breast.
Wild Game Outperforms Conventional Beef
If you have access to game meats, they consistently beat conventional beef for protein density. USDA data on alternate red meats shows that cooked elk delivers about 26.6 grams of protein per 100 grams, venison (deer) hits 26.5 grams, and ostrich reaches 26.2 grams. Cooked beef, by comparison, averages around 23.8 grams per 100 grams.
Emu stands out even further at 28.4 grams of protein per 100 grams cooked, making it one of the most protein-dense whole meats available. Bison lands at 25.4 grams, still a meaningful step above conventional beef. These game meats tend to be leaner, which is exactly why their protein-to-weight ratio is higher. Less fat in the meat means more of each bite is muscle fiber, and muscle fiber is where the protein lives.
Why Lean Cuts Always Win
The leanness of a cut is the single biggest factor in its protein density. Protein is concentrated in muscle tissue, so when a cut carries more intramuscular fat (the marbling you see in a ribeye, for instance), fat displaces some of that protein by weight. A lean sirloin steak from the cow’s lower back, a heavily worked muscle, has one of the highest protein-to-fat ratios of any beef cut. A well-marbled ribeye tastes richer but delivers fewer grams of protein per ounce.
This same principle applies across every animal. Chicken thighs with skin have noticeably less protein per serving than skinless breast. A pork chop from the loin is leaner and more protein-dense than a pork belly cut. If maximizing protein is your goal, choose the leanest option from whatever animal you prefer.
Seafood Comparisons
Fish and shellfish deserve a spot in this conversation. Yellowfin tuna is the standout, packing about 29 grams of protein per 100 grams cooked, with 89% of its calories coming from protein. That caloric efficiency rivals or beats chicken breast. Tilapia provides around 26 grams per 100 grams, and pollock comes in at 24 grams.
Shrimp offers roughly 23 grams of protein per 100 grams with only about 101 calories per serving, making it one of the most calorie-efficient protein sources available. Cod is leaner still at just 72 calories per 3-ounce serving, though its protein count is slightly lower at 19 grams per 100 grams. Salmon, while an excellent source of healthy fats, is less protein-dense at roughly 19 grams per 4-ounce serving because those fats take up more of the weight.
Dried Meats Pack the Most per Bite
If you’re looking purely at protein concentration by weight, dried meats blow everything else away. Removing water from meat shrinks the volume while leaving the protein intact, so you end up with a much denser product. Dried fish leads this category dramatically, with about 63 grams of protein per 100 grams, nearly double that of any fresh cooked meat.
Beef jerky contains around 30 grams of protein per 90-gram cup of pieces, or roughly 7 grams per individual piece. It’s a convenient, shelf-stable option, but it comes with trade-offs: jerky is often high in sodium and can get about 56% of its calories from fat depending on the brand and preparation. If you’re snacking on jerky for protein, check labels carefully since products vary widely.
Protein Quality, Not Just Quantity
Grams per serving only tells part of the story. How well your body can actually use the protein matters too. Meat in general scores extremely well on protein quality scales. Beef products tested for digestibility consistently score above 100 on the DIAAS scale (the current gold standard for measuring protein quality), meaning your body can absorb and use virtually all the amino acids present. A score above 100 indicates the protein is so complete and digestible that it can complement lower-quality proteins eaten at the same meal.
This is one area where all meats perform similarly. Whether you’re eating chicken, beef, pork, or fish, the protein you’re getting is complete, containing all nine essential amino acids in proportions your body can readily use. The differences in quality between meat types are small enough that they shouldn’t drive your choice. Pick based on protein quantity, calories, cost, and what you actually enjoy eating.

For most people buying meat at a regular grocery store, skinless chicken breast or turkey breast gives you the most protein for the least calories at the lowest price. If you’re open to seafood, canned tuna is hard to beat for convenience and protein density. And if you can source game meats, venison, elk, and bison all outperform conventional beef while staying leaner.
