About these numbers
The figures come from the USDA FoodData Central entry “Chicken, broilers or fryers, breast, meat only, cooked, roasted”. They describe the cooked food. Cooking changes the water content, so calories per 100 g differ from the raw food. They are reference averages, so brands, ripeness, cuts and recipes shift the real number. Treat them as estimates, and weigh food for the closest result.
