Chicken breast and turkey breast are often cited as the top protein sources, but several meats actually pack more protein per serving. Dried meats like jerky and biltong lead the pack by a wide margin, while among fresh meats, game animals like elk, deer, and emu consistently outperform standard beef and chicken.
The answer depends on whether you’re comparing raw cuts, cooked portions, or dried products, and whether you care more about total protein or protein relative to calories. Here’s how the major categories stack up.
Dried Meats Top the List
If you’re purely chasing protein density, dried and cured meats are in a league of their own. Beef jerky delivers 10 to 15 grams of protein per ounce. Biltong, a South African style of air-dried beef, is even more concentrated: 16 grams of protein in a single ounce, with just 80 calories and 2 grams of fat. That works out to roughly 57 grams of protein per 100 grams of product.
The reason is simple. When meat is dried, it loses most of its water weight while retaining all of its protein. You’re essentially eating concentrated muscle tissue. The tradeoff is sodium: most jerky and biltong products contain significant salt, so they work better as a high-protein snack than a dietary staple.
Game Meats Beat Standard Beef
Among fresh, cooked meats, game animals consistently deliver more protein per bite than conventional beef. USDA data on cooked values per 100 grams tells the story clearly:
- Emu: 28.4g protein per 100g cooked
- Elk: 26.6g
- Deer (venison): 26.5g
- Ostrich: 26.2g
- Bison: 25.4g
- Beef: 23.8g
Emu leads fresh meats at nearly 28.5 grams of protein per 100 grams when cooked. That’s about 20% more protein than the same weight of cooked beef. Elk and venison land in the middle, each delivering around 26.5 grams. Even bison edges out conventional beef by a meaningful margin.
These game meats are also leaner than beef, which is part of why their protein percentage is higher. Less fat per gram means a greater share of the meat’s weight comes from protein. For anyone who can find elk, bison, or venison at a local butcher or specialty grocer, they’re among the most protein-efficient meats available.
The Best Beef Cuts for Protein
Not all beef is created equal. The leanest cuts concentrate more protein per gram because they carry less intramuscular fat. Among raw cuts (lean portion only, per 100 grams), top round leads at about 23 grams, followed by sirloin tip at around 21 grams. Choice-grade cuts, which have more marbling, contain slightly less protein than select-grade versions of the same cut, though the difference is small.
Once cooked, beef averages roughly 24 grams of protein per 100 grams. Cooking drives off water, which concentrates the protein. A raw portion that starts at 125 grams will typically shrink to about 100 grams after cooking, so if you’re tracking protein, weigh your meat after it comes off the heat for the most accurate count.
Chicken and Turkey Are Nearly Identical
Chicken breast and turkey breast, both roasted, deliver exactly 24 grams of protein per 3-ounce serving. There’s no meaningful difference between the two for protein purposes, so choose whichever you prefer. Both are leaner than most red meat, which means a higher percentage of their calories come from protein.
Chicken tends to shrink slightly more during cooking than red meat. About 130 grams of raw chicken breast cooks down to 100 grams. This is worth knowing if you’re meal prepping and weighing portions in advance.
Fish and Seafood Vary Widely
Fish can rival or exceed poultry for protein, but the range across species is broad. Tuna sits at the top. A 6-ounce cooked bluefin tuna fillet contains about 51 grams of protein, while yellowfin tuna delivers just under 50 grams in the same portion. Wild-caught coho salmon provides around 46.5 grams per 6-ounce fillet, and tilapia comes in at 44.5 grams.
Lean white fish like cod and snapper are also strong choices, with a cooked cod fillet providing about 41 grams of protein. Fattier fish like salmon and mackerel have slightly less protein gram-for-gram because more of their weight comes from omega-3 fats, but they’re still excellent protein sources with added nutritional benefits.
Shellfish trails behind. Crabmeat, shrimp, and lobster provide about 6 grams of protein per ounce, compared to 7 grams per ounce for most fish, poultry, and red meat.
Organ Meats Hold Their Own
Organ meats are often overlooked, but they’re competitive with muscle meats for protein. A 3-ounce serving of cooked beef liver contains about 25 grams of protein. Lamb liver is slightly higher at 26 grams per 4-ounce raw serving. Pork liver provides 22 grams, and chicken liver about 21 grams in the same raw portion size.
Liver is also far richer in vitamins and minerals than muscle meats. It’s one of the most nutrient-dense foods available by virtually any measure. The flavor is polarizing, but from a pure protein-per-calorie standpoint, it belongs in the same tier as chicken breast and lean beef.
How Cooking Changes the Numbers
Raw and cooked protein values can look quite different, and the reason is water loss, not protein gain. When meat cooks, moisture evaporates as steam and drips out as cooking juices. The protein itself stays intact. A piece of beef that weighs 125 grams raw will weigh about 100 grams cooked. Fish shrinks even more: 155 grams raw typically yields around 120 grams cooked.
This matters for two reasons. First, if you see protein values listed “per 100 grams,” cooked numbers will always look higher than raw numbers for the same cut. Emu, for example, jumps from 22.8 grams raw to 28.4 grams cooked per 100 grams. The protein didn’t increase; the water left. Second, if you’re tracking macros, measure your portions after cooking for the most accurate protein count.
Quick Protein Ranking at a Glance
Putting it all together, here’s how the major categories rank for protein density in cooked or ready-to-eat form:
- Dried meats (jerky, biltong): 33 to 57g per 100g
- Emu: ~28g per 100g cooked
- Elk and venison: ~26.5g per 100g cooked
- Ostrich: ~26g per 100g cooked
- Bison: ~25.4g per 100g cooked
- Tuna (bluefin or yellowfin): ~30g per 100g cooked
- Chicken or turkey breast: ~28.5g per 100g cooked
- Beef (lean cuts): ~24g per 100g cooked
- Salmon: ~25g per 100g cooked
- Shellfish: ~21g per 100g cooked
For most people, the practical winners are chicken breast, turkey breast, tuna, and lean beef, simply because they’re affordable and widely available. If you have access to game meats like elk or bison, they offer a genuine protein advantage over conventional beef. And if portability matters, a bag of biltong or jerky packs more protein per ounce than any fresh meat you can buy.
