A subject I know very well and yet this book was jam packed with new things to consider. Such as, studies show damp conditions and overcrowding leads to less allergies in children.
The biggest take away is we are all different, one diet doesn't fit all but variety is the spice of life (as long as it is unprocessed!).
And how funny that you lose doctor in your title if you become a professor (that was not in the book!).
