Again, I think you are seeing way more than is there. I do not see a "loaf perched on her arm" and the more I look at it, I am not even sure if there is anything laying on the rocks to the right of the cross, just the color of the rocks.  As to how "healthy" Jesus looks. I have seen very few crucifixes and paintings of Christ on the cross where he looks as beaten and torn up as He would have been in reality. It's just the nature of the artwork.
