Precisely because paleo man was more animal-like. Less cerebration was involved in deciding what to eat. Animals don't synthesize textured protein from soybean, they eat what is natural (instinctive) for them to eat, to the extent that Amazonian parakeets (and many other species) eat a particular kind of clay to neutralize the toxins they ingest in their fruit-based diet. If we do synthesize our food, and process it more than any other animal, we should consider whether what we're doing is good for us.
