I got this book from a co-worker who was going bonkers over this book and how this has helped him. But after reading this book, I felt it was much ado about nothing. According to me, blindly believing these type of books is very dangerous. Hypertension is a significant problem. I agree that lifestyle changes could play a significant role in reducing the incidences of hypertension, but it should be done under medical supervision only and not by someone who has not even seen you. These type of decision should be discussed with your medical doctor first and implemented only after their approval.
