While watching the DVD's, I heard David Wolfe speak about Dr. Yu . It seems that Dr. Yu has received a government grant to study detoxification on Gulf War soldiers and on 9/11 survivors/emergency responders. He is doing a tremendous job detoxing patients and has the records/studies to prove it. I hear that he examines the toxins in belly fat before and after treatment. Here is a link to his website he is in Maryland.
