I can't believe how many times people ask me about whether Ayurveda has any similarities with the Blood Type Diet (BTD) - a diet by Dr Peter D'Adamo (in his book The Eat Right Diet). 

I always tell them that they're in luck, because in 2000 I did a research paper on exactly this topic!  I too, was fascinated by the many similarities I could see between Ayurveda and BTD.
