Duck (meat only, roasted) vs Chicken breast (cooked)

The short answer

Both roasted poultry, meat only. Duck is much richer — far more fat and calories per 100 g, with more iron; chicken breast is lean and higher in protein per calorie. Duck for a rich, flavourful meat, chicken for everyday lean protein.

Duck (meat only, roasted) and Chicken breast (cooked), per 100 g and per portion. A gap means USDA has no value for it — not zero.

Common questions

Is Duck (meat only, roasted) or Chicken breast (cooked) better?

Neither is “better” on its own — it depends what you want from it. The table shows where each is higher; the short answer says when each one fits. Compare on the same basis (per 100 g) and pick for your dish and your goal.

How were these numbers worked out?

Straight from USDA FoodData Central for the generic form of each food, per 100 g. We show the portion view too, but portion sizes differ between foods, so per 100 g is the fair comparison.

Why does one column say “no data”?

Because USDA has no value for that nutrient in that food — so we leave it blank rather than print a 0 that would read as “none”. A real zero from USDA still shows as 0.
