Since I first went to India twenty some years ago, there's been a palpable change. There's now pizza everywhere, meat is much more popular than it's ever been. Vegetarianism is "that quaint thing our parents did."

It doesn't do a lot of good for your health to move from red meat to white meat, but it gets you further down the road towards making more substantial changes later.

I'm thinking of people in rural Japan and China, where McDonald's hasn't yet arrived. These are the thinnest, healthiest, longest-lived people with the least risk of cardiovascular disease and diabetes.

Not only are the studies themselves often lacking even face value, but they also drain badly needed funds away from patient care needs.

Medicine is often conservative and slow to incorporate something that wasn't there before and that we're afraid people are going to laugh at us for. But, the beauty of music is - well, a couple things. There are no side effects that are harmful. Music doesn't do that. It doesn't have any negative effects whatsoever. So I do think it's going to come, but I think it's a new idea for people.

Chimpanzees will eat a little bit of meat. But, they never eat dairy products, and no other animal would do that.

If some people think, "Why am I eating a dead bird soaked in poop?" I think if some people get disgusted by that, it's all to the good. Their coronary arteries will be healthier.
