The name of the book is called Eat Right For Your Type.  There are also books in the same vane such as Live Right For Your Type etc etc.  Mainly though there are four different blood types.

A,AB,B and O

So there are four different ways to eat for each blood type.  The site of Dr A’Adamo’s is at:

You’ll find lots of studies on there.  The book doesn’t really have much more than the site contains lol.  It’s just that I bought it and then noted in it that he had a web site.  Here is a site where I found diet sheets for each blood type:

I actually think it’s worth the read and worth trying myself and I’d urge you to do searches on lectins and agglutins on Google also because there are pages all over the web that explain the basis of the diet.  You can simply input ER4YT and it brings up thousands of references.  Best of luck.
