Chicken Breast vs Chicken Thigh: Full Nutrition Comparison
By Johnny L. · Published August 3, 2026
Chicken breast and chicken thigh are the two most commonly eaten cuts, and the debate between them tends to get oversimplified. Breast is "the healthy one." Thigh is "the tasty one." Neither characterization is wrong, but both miss the nuance. Yes, breast is leaner and higher in protein per 100g. But thigh edges it out on zinc, B12, and iron — and the calorie difference between the two skinless cuts is smaller than most people think. The data below comes from USDA FoodData Central and covers roasted meat, both with and without skin, per 100g.
Side-by-Side: Meat Only, Roasted
| Nutrient | Breast (per 100g) | Thigh (per 100g) |
|---|---|---|
| Calories | 165 kcal | 179 kcal |
| Protein | 31.0g | 24.8g |
| Total Fat | 3.6g | 8.2g |
| Saturated Fat | 1.0g | 2.3g |
| Cholesterol | 85mg | 133mg |
| Sodium | 74mg | 106mg |
| Iron | 1.04mg | 1.13mg |
| Zinc | 1.0mg | 1.92mg |
| Vitamin B6 | 0.6mg | 0.46mg |
| Vitamin B12 | 0.34µg | 0.42µg |
| Selenium | 27.6µg | 27.1µg |
| Phosphorus | 228mg | 230mg |
Calories and Macros: What Actually Differs
On protein density, breast wins clearly. At 31.0g per 100g versus thigh's 24.8g, that is a genuine 25% advantage. For someone eating 200g of chicken at dinner, breast delivers roughly 62g of protein against thigh's 50g — a meaningful gap if protein targets are tight. The fat difference is real but not dramatic in absolute calorie terms. Breast carries 3.6g of total fat per 100g; thigh carries 8.2g. That 4.6g gap translates to about 41 extra calories per 100g. If you're eating a 150g portion, the difference is roughly 62 calories — the equivalent of two Oreo cookies. Whether that matters depends entirely on where you are relative to your daily targets. Saturated fat is where the gap matters more in a clinical sense. Thigh has 2.3g per 100g versus breast's 1.0g. For someone closely managing saturated fat intake — a post-cardiac-event diet or strict therapeutic nutrition — breast is the clearer choice. For everyone else, both cuts are well within reasonable ranges on any sensible eating pattern. Cholesterol is higher in thigh (133mg vs 85mg per 100g), though dietary cholesterol's effect on blood cholesterol is more variable than once believed. Current evidence suggests most people are not meaningfully sensitive to dietary cholesterol at typical food intake levels, though individual responses differ.
The Skin Factor
| Nutrient | Breast with Skin | Thigh with Skin |
|---|---|---|
| Calories | 197 kcal | 232 kcal |
| Protein | 29.8g | 23.3g |
| Total Fat | 7.8g | 14.7g |
| Saturated Fat | 2.2g | 4.1g |
What the Skin Numbers Mean in Practice
Adding skin has a larger effect on thigh than on breast. Skinless breast sits at 165 kcal and 3.6g fat; skin-on breast climbs to 197 kcal and 7.8g fat — roughly a 2x increase in fat content. Thigh makes a bigger jump: 179 kcal and 8.2g fat without skin versus 232 kcal and 14.7g fat with skin. For people who roast bone-in, skin-on thighs — which is genuinely one of the better ways to cook chicken — the fat and calorie numbers are significantly higher than the skinless figures that dominate most nutrition comparisons. That is not a reason to avoid them, but it is worth knowing if you are logging intake carefully. Removing skin before eating captures most of the fat reduction even if you cook with the skin on, since much of the fat sits in and directly under the skin layer. Cooking skin-on and removing before eating is a reasonable middle ground that preserves moisture during cooking without retaining all the added fat.
Where Thighs Actually Win
The micronutrient picture favors thigh on several fronts. Zinc comes in at 1.92mg per 100g in thigh versus 1.0mg in breast — nearly double. Zinc supports immune function, protein synthesis, and wound healing, and chicken thigh is a genuinely useful dietary source. Breast's 1.0mg per 100g is not negligible, but thigh is the stronger option if zinc is a priority. Vitamin B12 is modestly higher in thigh at 0.42µg versus 0.34µg per 100g. Both cuts are solid B12 sources — a 150g serving of either provides a meaningful portion of the 2.4µg daily requirement — but thigh edges ahead. Iron follows the same pattern: 1.13mg versus 1.04mg, a small but consistent advantage for thigh. Beyond the nutrient data, thigh has practical advantages that matter in a real kitchen. It is cheaper per pound at most retailers — often 30–50% less than skinless boneless breast. It is far more forgiving to cook. Breast has a narrow window between properly cooked and noticeably dry; thigh contains enough fat and connective tissue that it stays tender over a wider range of internal temperatures. This is why most chefs, when cooking for flavor rather than macros, reach for thighs first.
Which Should You Choose?
- Choose breast if protein per calorie is your primary goal — 31g protein at 165 kcal per 100g is one of the most favorable ratios of any whole food. It is the right call for aggressive protein targets on a calorie budget.
- Choose thigh if you want better zinc, B12, and iron with similar selenium and phosphorus — and if you find the flavor more satisfying. A more satisfying meal tends to be more sustainable in practice.
- For most people, the choice between the two cuts matters far less than the choice between skinless and skin-on. Removing the skin roughly halves the fat content of thigh and cuts breast's fat by more than half — a bigger nutritional lever than switching cuts.
- Budget-conscious shoppers get more mileage from thigh. The lower price point means you can eat more protein per dollar, which often matters more than the per-gram protein difference between the two cuts.
- There is no nutritional reason to avoid either cut. Both are lean, high-quality protein sources by any reasonable standard. The framing of breast as "healthy" and thigh as an indulgence is a cultural artifact, not a nutritional conclusion.
