Any philosophical discussion (which marc's is turning into) has to start with a definition of terms (it usually ends there, too). As far as I know, nobody has defined what it means to be healthy yet. Marc, if I define 'good health' as being able to withstand ancient threats to life, such as icy temperatures and hungry mastadons, does your diet still prove best? We are decendants from these 'healthy' people. The less 'healthy' would have died before they could reproduce. So, healthy = lots of muscle and endurance. Can your foods promise that? I don't define health exactly that way, but some definitely do. Please give us your definition.
