Meat consumption is just as dangerous to public health as tobacco use... It's time we looked into holding the meat producers and fast-food outlets legally accountable.

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

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.

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.

The Stone Age gave us arrow heads and eventually knives, and that allowed us to kill animals in ways you couldn't before, and once you had them you were able to remove the skin and bones.

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

In my own life, I decided to leave meat off my plate in medical school, but was a bit slow to realise that dairy products and eggs are not health foods either.
