Gnarrrggghh! Zombie Food Pyramid
 

I have to remember it, when will be the time to make a "purifing diet"...

Ahh thats my problem, just not getting enough of that all important "brain" section...

Yep, ourdays it's hard to find enough humans with a good brain, seems the brainless kind is in the majority.
:(

Well, in case of doubt you always have at least the bones :)

Looks like, in order for zombies to have a healthy diet, a lot of brainless bodies will be left uneaten, most of them with most of their other organs, some of them without some of them. This scientifically agrees with data from movies.
