Chicken Breast, Skin Removed Before Cooking
from the NCCDB
According to Cronometer, 100g gives 30.91 grams of protein. This means 100 grams of the edible portion (AKA the meat) will give the aforementioned protein amount?
I think there is no bone in any food. Those nutrients are only for the edible part. It would not make sense to count the bone if you can not eat it anyway. You can check this by adding together the wather, protein and fat. In your case (the chicken breast) you will see that you get exactly 100g.
