A piece of bread contains 70 Calories. But how much of this is actually 
absorbed by the body.  If it was 100%, dung beetles would starve to death.
Since there are dung beetles, we can conclude < 100% of the calories in 
bread is absorbed.

Also are there different efficiency for bread, apples and pure sugar?

Thank you
