Chicken breast versus cooked salmon: calories, macros and portion trade-offs
BiteCal 編輯團隊 · · 閱讀約 4 分鐘
The named chicken breast and cooked salmon references contain 165 and 206 kcal per 100 g respectively. Compare equal weights first, then calculate the portions and additions you would actually eat.
Named foods on the same 100 g basis
| USDA reference | kcal | Protein | Carbohydrate | Fat | Fiber |
|---|---|---|---|---|---|
| Chicken, broilers or fryers, breast, meat only, cooked, roasted | 165 kcal | 31 g | 0 g | 3.6 g | 0 g |
| Fish, salmon, Atlantic, farmed, cooked, dry heat | 206 kcal | 22.1 g | 0 g | 12.4 g | 0 g |
What exactly is being compared?
For the numbers in this guide, chicken breast means “Chicken, broilers or fryers, breast, meat only, cooked, roasted” (USDA FoodData Central 171477). It contains 165 kcal per 100 g edible portion. This reference is roasted chicken breast meat only. Skin-on chicken, breaded tenders and raw chicken weights do not describe the same food. Keeping that definition attached to the number prevents a plain ingredient from being mistaken for a prepared meal.
The second food is “Fish, salmon, Atlantic, farmed, cooked, dry heat,” rather than an unspecified cooked salmon dish. Preparation is part of the comparison: a raw ingredient, cooked grain, spread or complete meal is not automatically interchangeable with another food just because both appear in a calorie search.
Calories on an equal-weight basis
The comparison food is “Fish, salmon, Atlantic, farmed, cooked, dry heat” (FDC 175168), which contains 206 kcal per 100 g. At equal 150 g weights, the chicken breast reference supplies 247.5 kcal and cooked salmon supplies 309 kcal: a difference of 61.5 kcal. That is a calculation for these records, not a universal ranking of foods or an instruction to exchange equal portions.
The gap per 100 g is 41 kcal. Doubling both weighed amounts doubles that calculated gap; halving both halves it. This explains the table without claiming that either food has a fixed portion or that a lower-energy choice provides an identical eating experience.
Chicken breast calories for weighed edible portions
| Edible amount | Calculated calories | Protein | Carbohydrate | Fat | Fiber |
|---|---|---|---|---|---|
| 75 g | 123.8 kcal | 23.3 g | 0 g | 2.7 g | 0 g |
| 100 g | 165 kcal | 31 g | 0 g | 3.6 g | 0 g |
| 150 g | 247.5 kcal | 46.5 g | 0 g | 5.4 g | 0 g |
| 225 g | 371.3 kcal | 69.8 g | 0 g | 8 g | 0 g |
| 300 g | 495 kcal | 93 g | 0 g | 10.7 g | 0 g |
Protein, carbohydrate, fat and fiber
The same 100 g reference provides 31 g protein, 0 g total carbohydrate, 3.6 g fat and 0 g fiber. For the illustrated 150 g portion, those amounts become 46.5 g protein, 0 g carbohydrate, 5.4 g fat and 0 g fiber. Calories and individual nutrients describe different parts of the food, so keep all of them on the same portion basis when reading the table.
For cooked salmon, the same 100 g record reports 22.1 g protein, 0 g carbohydrate, 12.4 g fat, 0 g fiber. Read those values as a profile rather than a single score. The combination you want depends on the rest of the meal and any personal nutrition requirements.
Why the realistic portion matters
A weighed 150 g portion provides approximately 247.5 kcal: 150 × 165 ÷ 100. A smaller 75 g portion gives 123.8 kcal, while 225 g gives 371.3 kcal. These are calculated amounts of the named food, not claims about the weight of a standard piece, cup or restaurant serving.
The reference describes roasted breast meat, with bones and skin excluded. A raw breast weight should not be multiplied by this cooked-food value because roasting changes the relationship between mass and nutrients.
Compare complete dishes, not isolated ingredients
For meal prep, weigh the edible chicken after cooking if using this entry. Divide the cooked batch between containers by weight; pieces that look equal can differ in thickness and mass.
Chicken coated in breadcrumbs, served with skin, or covered in a creamy sauce needs additional accounting. The plain roasted-meat number cannot establish the energy of a complete restaurant chicken dish.
For an explicit ingredient example, 150 g of the named chicken breast plus 5 g olive oil gives approximately 291.7 kcal. The chicken breast contributes 247.5 kcal and the oil contributes 44.2 kcal. This is an illustrative two-ingredient calculation, not a tested recipe or a claim that chicken breast is always served with oil.
A practical side-by-side review
Write down the edible grams of chicken breast in one version and of cooked salmon in the alternative. Include any accompanying foods that change between versions. A swap that uses different amounts of bread, dressing or topping will not have the same calorie difference as the equal-weight food comparison. Keeping the ingredients visible explains the result.
In BiteCal, start with a photo of the chicken breast portion and the rest of the meal. Review the proposed food name, preparation, amount and visible additions before saving the calorie and macro estimate. If you already know the gram weight, use it as a check rather than accepting a visually plausible portion. A photo cannot establish a hidden oil quantity or replace the identity of a packaged product.
The nutrient figures come from USDA SR Legacy, final release April 2018. They provide a reproducible reference for the named food rather than a laboratory result for your own serving. Use the current package or restaurant information when it describes your exact product more closely. Rounding explains small differences between displayed portions; calculations here use the retained unrounded reference values.
常見問題
Which reference has fewer calories per 100 g?
For these records, chicken breast has the lower value: 165 versus 206 kcal per 100 g. The comparison applies to the named preparations.
Does equal weight mean the same serving?
No. The equal 150 g example isolates food weight; the amounts you actually eat may differ. Calculate the portions planned for each dish.
How much protein does chicken breast contain?
The named reference supplies 31 g per 100 g, or 46.5 g in the worked 150 g portion. Protein grams describe a nutrient rather than total food weight.
Should I choose only from the lower calorie number?
Consider the rest of the meal, portion, preparation and nutrient profile. Chicken coated in breadcrumbs, served with skin, or covered in a creamy sauce needs additional accounting. The plain roasted-meat number cannot establish the energy of a complete restaurant chicken dish.
