What Has More Protein, Turkey or Tuna?

If you’re asking what has more protein, turkey or tuna, the short answer is: it depends on the cut and serving size, but turkey breast usually edges out canned tuna by a small amount per cooked 3-ounce serving.

That said, the difference is not huge. Both are high-protein, lean options that can fit well into a muscle-building or fat-loss diet. The better choice often comes down to calories, sodium, mercury concerns, taste, and how you plan to eat it.

Protein comparison: turkey vs tuna

For a common serving size, roasted skinless turkey breast is usually around 25 to 26 grams of protein per 3 ounces cooked. Canned light tuna in water is often around 20 to 22 grams per 3 ounces drained. Fresh tuna steaks can be closer to turkey, and sometimes nearly the same.

So if you want the simplest answer to “what has more protein turkey or tuna,” turkey breast usually wins by a small margin. But in real meals, both foods are excellent protein sources, and either one can help you reach a daily protein target.

Calories, fat, and satiety

Turkey breast and tuna are both lean, but their nutrition profiles differ a bit. Tuna often has very low fat and can be slightly lower in calories, while turkey breast may be a touch higher in calories depending on how it is cooked and whether skin is included.

If you’re choosing based on fullness, either can work well because protein is the main factor. If you’re comparing foods for a cut or weight-loss plan, the version matters: plain turkey breast and tuna packed in water are very different from deli turkey, tuna salad made with mayo, or breaded, fried versions.

Other nutrition differences to consider

Tuna brings more omega-3 fats than turkey, especially in some varieties of fish. That can be a plus for heart health. Turkey is often easier to find fresh, and it may be a better fit if you want a lower-mercury protein choice for frequent use.

Two things to keep in mind: tuna can be higher in sodium if it’s canned, and some tuna varieties contain more mercury than others. Pregnant people, young children, and anyone eating tuna often should follow seafood guidance from trusted public health sources.

Which is better for your goal?

For pure protein per serving, turkey breast usually has a slight edge. For variety, convenience, and healthy fats, tuna is also a strong option. The best choice depends on your goal and the rest of your diet.

If you’re trying to build muscle, hit a daily protein target, or recover from workouts, consistency matters more than the turkey-vs-tuna difference.

Tips

Compare cooked, drained, or plain portions instead of guessing from raw weight.
Choose turkey breast or tuna in water if you want the leanest protein options.
Watch toppings and mixes: mayo, cheese, and breading can add a lot of calories fast.
If you eat tuna often, vary the type and follow mercury guidance.
Use a meal photo tracker to estimate macros more consistently when you’re comparing high-protein foods.
