“The more the person believes in the practice, the greater the impact it has on the brain.”
— Andrew Newberg

Greetings, SuperFriends!

Today we are rejoined by Dr. Andrew Newberg. Dr. Newberg is currently the Associate Director in Charge of Research at the Marcus Institute of Integrative Health at Thomas Jefferson University and Hospital in Philadelphia. He is also a Professor in the Departments of Emergency Medicine and Radiology at Thomas Jefferson University, and the adjunct professor in the Department of Psychology at the University of Pennsylvania. (Try saying all that out loud!)

Dr. Newberg is also, as you know from our previous episode, which I highly recommend, one of the preeminent experts on the study of neurotheology, which looks into how religion affects our brain – a very interesting topic. He's published over 200 peer-reviewed articles on the subject, and he's authored a number of books, including How God Changes Your Brain, Why God Won’t Go Away: Brain Science and the Biology of Belief, and his most recent book The Rabbi's Brain, which is what we wanted to talk about in the episode.

Now, I want you to avoid the temptation to go “Oh, this is an episode about Jewish stuff and I'm not Jewish – who cares…”, because I'm also not very Jewish, despite being a Levi and born into Judaism. As we learn from our episode with Andre Norman and many other episodes, you don't have to be of a particular faith to learn some of the lessons and some of the values from it – you don't even have to particularly be faithful, as there are a lot of good stuff in there anyway.

So, my goal for this episode was to understand how a specific religion (in this case, Judaism, but it could be anything) actually affects our brain, whether it benefits or hurts us, and what are the things that are happening in the brain. I was especially interested in this because of my fascination with not only the brain itself, but also meditation and how it changes our brain. So I wanted to know, is meditation different from reciting Hail Mary, reading the Shema, or doing the morning prayer in Islam?

In the episode, we answer all these questions and many more – I think you are really going to enjoy this episode, as I always enjoy chatting with Dr. Newberg!

    Great interview with Dr. Greg Wells! He mentioned a doctor from Colorado around the 42:30 point of the podcast, discussing turmeric and black pepper. I couldn’t make out the doctor’s name. Can you provide me with his full name and maybe his website or contact info. Interested in his products.
