This is pretty hard core... I wouldn't adopt it all the way. But many of the points brought up in this nutrition book make a dramatic improvement on post race recovery and rebuilding our body. I have adopted many of the principles in here and I haven't been sick or injured once this year (and I have four kids bringing germs home from school...). Last year... I constantly had running injuries... this year so far, nothing. http://www.amazon.com/Paleo-Diet-Athletes-Nutritional-Performance/dp/1594860890
