The simple answer

For the most common comparison—cooked skinless chicken breast versus cooked salmon—chicken is higher in protein. USDA food data show cooked chicken breast has about 31 grams of protein per 100 grams, while cooked Atlantic salmon has about 22 grams per 100 grams.

In practical terms, a typical 3-ounce serving of chicken breast usually gives you more protein than the same-size serving of salmon. If your main goal is maximizing protein with fewer calories, chicken breast is often the more protein-dense pick.

Why the answer can change

Not all chicken and salmon are the same. Chicken thighs, drumsticks, and breaded or fried pieces have different protein and calorie counts than chicken breast. Salmon also varies by species and preparation method, and canned salmon can differ from fresh or cooked fillets.

Cooking method matters too. Water loss during cooking can make protein look higher per 100 grams because the food shrinks, even though the total protein in the original piece stays about the same. That’s why serving size and cooking style are important when comparing foods.

Protein is only part of the decision

Salmon may have less protein than chicken by weight, but it offers benefits chicken doesn’t match as well: heart-healthy omega-3 fats, vitamin D, and often more selenium. Chicken is usually lower in fat, especially if you choose the breast and remove the skin.

So the “best” option depends on your goal. If you want the highest protein per calorie, chicken breast usually wins. If you want a protein-rich food with more healthy fats, salmon is an excellent choice. Both can fit into a balanced diet.

How to use this in real meals

If you’re building meals for muscle gain, satiety, or fat loss, aim for a consistent protein target across the day rather than obsessing over one food. The NIH notes that most adults need about 0.8 grams of protein per kilogram of body weight per day, with higher needs for some active people.

A simple approach is to pair a protein source with vegetables and a high-fiber carb. If you’re tracking portions at home, Fitnit can help you stay consistent by estimating reps for bodyweight and dumbbell work, and it can also help you log meals from photos so you can keep an eye on protein intake without overthinking it.

Tips

• Choose skinless chicken breast if you want the highest protein per bite.
• Pick salmon when you want protein plus more omega-3 fats.
• Compare foods by cooked weight and serving size, not just by the label on the package.
• Watch for breading, frying, and heavy sauces, which can change calories much more than protein.
• If you train regularly, spread protein across meals instead of putting it all in one sitting.
