Chicken vs turkey: which lean protein is better?

Chicken and turkey sit next to each other in the meat case and in most people's mental category of lean protein. They are close relatives nutritionally, but they are not identical, and the differences show up exactly where lean-protein shoppers care most: protein per calorie, fat, iron, and sodium. We pulled both birds from our USDA-based index and lined them up. Here is what the numbers say, cut by cut and goal by goal.

Breast vs breast: the headline matchup

Start with the cuts most people actually buy. Raw chicken breast, skinless and boneless carries 120 calories, 22.5 grams of protein, and 2.62 grams of fat per 100 grams, with a Nutrient Density Score of 74. Raw turkey light meat, the white meat that includes the breast, comes in at 114 calories, 23.7 grams of protein, and just 1.48 grams of fat, scoring 75.

That is about as close as two foods get in our database, but turkey edges the raw comparison on three counts: slightly more protein, fewer calories, and roughly half the fat. Per calorie, turkey light meat delivers around 0.21 grams of protein per calorie versus 0.19 for chicken breast. Both are excellent. Turkey is a hair better.

One caution on turkey: buy it skinless. Raw turkey breast with the skin on jumps to 157 calories and 7.02 grams of fat per 100 grams, and its density score drops to 61. The skin alone erases most of turkey's lean advantage.

What cooking does to the numbers

Cooked figures matter because that is what lands on your plate. Roasted chicken breast, meat only concentrates to 165 calories and a substantial 31 grams of protein per 100 grams as moisture cooks off, with 3.57 grams of fat and a density score of 71. The protein-per-calorie ratio holds steady through cooking, so the raw comparison above still tells the true story. Whichever bird you pick, roasting or grilling without added fat keeps the numbers where you want them.

Iron: a real win for turkey

Iron is where the two birds separate most clearly. Raw chicken breast has 0.37 milligrams of iron per 100 grams. Turkey light meat has 0.73 milligrams, roughly double, and whole turkey meat, which blends light and dark, reaches 0.86 milligrams. None of these numbers make poultry an iron powerhouse compared with the foods in our iron-rich foods guide, but if you are choosing between the two birds and iron is on your radar, turkey wins every matchup in our index.

The extreme case is organ meat. Turkey liver packs 8.94 milligrams of iron per 100 grams and scores 96 on our index, and chicken liver is nearly identical at 8.99 milligrams with the same score of 96. If iron is the goal, either liver beats any muscle cut by an order of magnitude.

Sodium: a quiet win for chicken

Fresh poultry is naturally low in sodium, but chicken is lower. Raw chicken breast carries 45 milligrams per 100 grams while turkey light meat carries 113 milligrams and whole turkey meat 118 milligrams. All of these are modest next to processed forms, and that is the real sodium story: turkey pastrami holds 1,120 milligrams per 100 grams and scores just 42. The gap between fresh turkey and deli turkey is far bigger than any gap between the fresh birds. If sodium matters to you, the cut and the processing matter more than the species.

Dark meat vs white meat in both birds

White meat outscores dark meat in both species because dark meat carries more fat per calorie. You can see it in the blended cuts. Turkey light meat alone scores 75, while whole turkey meat, which mixes in the darker leg and thigh, slips to 73 with fat rising from 1.48 to 1.93 grams. On the chicken side, stewing chicken meat, a whole-bird blend, scores 66 with 6.32 grams of fat, well below the breast's 74.

Ground products show the same pattern in the package label. Fat-free ground turkey scores 77, the best score of any muscle cut in this comparison, with 23.6 grams of protein and under 2 grams of fat per 100 grams. Regular ground turkey drops to 61 because fat climbs to 7.66 grams, and ground chicken sits at 59 with 8.1 grams of fat. The word turkey or chicken on a ground-meat label tells you little. The fat percentage tells you almost everything.

• Skin is the biggest variable. Chicken skin from drumsticks and thighs runs 440 calories and 44.2 grams of fat per 100 grams, scoring 26 on our index. Removing skin changes the math more than switching birds.
• Dark meat is not a mistake. It brings more iron and more flavor. It is simply a less lean choice, and the scores reflect that.

The verdict, by goal

For maximum protein per calorie, turkey light meat takes it narrowly, and fat-free ground turkey is the strongest packaged option at a score of 77. For the lowest sodium, skinless chicken breast wins at 45 milligrams per 100 grams. For iron, turkey beats chicken at every cut, and either bird's liver crushes both. For everyday flexibility and price, skinless chicken breast remains an outstanding default at a score of 74, and no reasonable goal is hurt by picking it.

The honest summary: this is a comparison between two very good options, and the differences between cuts within each bird are larger than the differences between the birds. Skinless beats skin-on, white beats dark on leanness, and fresh beats deli by a mile. Want to run your own matchup?
