Well I don't know about the fat content of apples doing anything for the flavor as you would be hard pressed to find afruit lower in fat. Apples have an extremely low fat content. But I do agree apples somehow bring a nice flavor to the meat. I believe it is from the many vitamins and minerals that apples hold - especially the skin.

When I was youngermy family owned someapple andpear orchards in Southern Illinois that we hunted.Needless to say the deer were plentiful (and tasty).
