Type A1 versus type A2

Hello Dr. D'Adamo,
I was rereading the article in the Townsend Letter (Nov.1996) about serotyping and diet, and came to a section about there being two different categories of A type blood. It was suggested that A1 is similar to what you describe in your book. It goes on to say that type A2 persons can tolerate higher levels of animal protein. What distinguishes type A1 from type A2, and how would someone with type A blood determine which category they belong to? This might explain why one of my fellow students at Southwest College of Naturopathic Medicine is a type A but swears she feels better eating meat. Do you alter your recommendations to people based on these sub-categories of type A blood?
By the way, after just a week or so of carefully following the type O diet, I do feel better. It seems to give me the increased energy I felt when I first stareted the zone diet and was avoiding grains more carefully. I will keep you posted on my results.
