A very good book that is easily understood about ethnic genetic food needs is:
Your Body Knows Best by Anne Louise Gittleman
http://www.annlouise.com/23/diet-detox/21/
This book explains how BLOOD type, affects our tolerance and intolerance of certain foods. It is really interesting.
Within Europe there are several ethnic groups mixed in.
Some require some dairy, others can go vegan more easily, and the Mediterranean folks need their olive oil and their foods.
I found this book (which is not new anymore) at our library. It has served me well, as a good introduction to understanding that people are DIFFERENT from each other and therefore some need one type of eating that would not work for another.
This book is available used at Amazon too.
