I am confused by some of the things in the book regarding strength testing.  For hunters, it says to strength test Teacher, explorer, warrier and nomad.  When I did, it shows strong nomad.  But after searching on the board, I see most responses say that is not possible.  

That sounds like a typo in the book to me. Teacher, Explorer, Warrior, and Nomad are the possibilities for ABs. O's can only be Hunter, Gatherer, or Explorer.

To be honest, I never took a close look at the "strength testing" part of the book. I figured out my genotype from the advanced calculator in the back of the book and read through the descriptions of the genotypes I or my kids could be.

That does sound like it.  And as far as the secretor testing goes, I never have done it, as according to the charts, with my measurements, I am always a hunter, either being a secretor or non, so don't see the need for that test.  Unless, I am missing something?

If you're following the Hunter diet in the book, then there's no need for the secretor test.

If you decide to go for a personalized SWAMI at some point in the future, secretor testing is important information. I measure out to be a Gatherer, regardless of secretor status.  My SWAMI food list differs widely from the Gatherer diet in the book, including many Type O food values. When I got my secretor status, SWAMI shifted the foods even more- taking away some grains (that I couldn't tolerate anyway) and giving me avocados, coconut oil, and lentils. Some vegetables and fruits shifted values as well.

Good to know.  I will do the SWAMI at some point in the future.  Guess I will take out the yogurt again.  Have been thinking it good for the diverticulitis, and that maybe there is the case where such an issue might override the fact that it is an avoid.  So then I tried to be a nomad.  Ha, funny how our minds work.  I did not have the DV problem for the last two years when eating as a hunter,  but when I took out walnuts and nuts and put in some yogurt, it began.  Let's see how it goes.  Thank you.
