There are inconsistencies between the different books. Why?
The different books are in different stages of upgrade or complexity. For example:
First book (Eat Right 4 Your Type) was a basic synthesis of the concept. It had to make some judgements regarding homogenizing information if it was secretor status specific. If a food was deemed a more serious avoid for a non secretor than it might be as a neutral or beneficial for a secretor, then the non-secretor value was used.
The Second Book (Live Right 4 Your Type) had secretor status differences and a very small number of food value changes, reflecting the advances in basic scientific knowledge.
The 'little books' (Food and Beverage Guides) Are a mass market book, very simplified, with largely just secretor guidelines and with a few of the altered values included.
