Things worth knowing
- Raw skinless breast is about 120 kcal per 100 g. Cooking removes water and concentrates the food, so the same piece of meat rises to about 165 kcal per 100 g once roasted. Weigh raw or cooked consistently, but do not mix the two.
- Leaving the skin on raises roasted breast to roughly 197 kcal per 100 g and more than doubles the fat.
- Breading and frying can take the same cut past 260 kcal per 100 g.
- Chicken breast is a strong source of selenium, niacin, and vitamin B6.
