A transistor is nowhere near the complexity of a neuron, but networks of them do computational mathematics faster then any human in existence can.
We don't eat cells - we consume relatively simple nutrients from them. Our bodies carry around a strong acid hydrolysis system for the exact purpose of obliterating all that "sophisticated" internal structure.
For that matter, we have no idea what our ancestors were adapted to. The human body has spanned the range and breadth of ecosystems on this planet, and the survivors of that have passed down what they think is safe to eat by tradition, not science.
