Do you expect a short and concise answer to that ? :-)
Go to the Paleodiet Symposium archives and read, read, read.
Also read other books on paleodiet, archeology, zoology, biology,
anthropology. And hang on to the idea that what is best for man is
what is the natural, and to the idea that metabolism is so complex
that we will probably never know exactly what is best to eat, based
only on biochemical knowledge, so we have to find out _what_ is natural.
