Query: Is a little consistency too much to ask?

While I find the concept of eating for your blood type intriguing, I was really disappointed in the quality of this guide book. The book is supposed to be specifically for those who, like me, have Type B blood. I found repeated instances where the tables would list a food as being one to avoid, then the text of the same segment would tell us to try is as an alternative. Can I have Barley or not? Is amaranth a good substitute for wheat or not? Specific questions posed to the website resulted in a generic email response telling me to check out the website. No answers were ever found. Pity they couldn't take a little more care about the people they supposedly are trying to help.
