I read the blood type diet when it came out and determined that it was long on interesting concept and short on supporting research and documentation.

However.

I recently had someone talk it up to me and pulled out my copy to look a few things over.

The list of things he specifically recommends *against* for type Os are foods that I have independently determined don't react well for me.

Did I remember from his list subconsciously? Possibly, but I read the book around 1997 and only just started in on food sensitivities in the last 3 years, so I'm guessing not after 10 years.

I have no opinion at all about his underlying theories or its validity for other blood types, but I certainly found the correlations for me fascinating.
