Yes, I believe Bill Clinton was referring to Dean Ornish’s heart trials. Dr Ornish has been a physical consultant to President Clinton since 1993*, and now Clinton is finally taking the Ornish diet seriously. So far he has lost a lot of weight on the diet, lets hope is he strict enough to actually reverse his heart disease, as the patients who were not very strict in the heart trials actually saw their disease worsen, but at a slower rate. It is interesting that Bill Clinton has been aware about the heart trials for decades but failed to mention it to the public despite heart disease being the number one cause of death in the U.S., not that he would have been allowed to anyway.

Hey veraveggie: Veganism is parallel to a pregnancy: either one is or one isn't. Other dietary choices come under other terms. Much of the reason our world is in the toilet is due to our apathy and fear of standing up against the wrongs against human and non humans . Peer pressure ridicule requires courage to face over time. Yes! You would do well to "shudder" knowing of the systemized torture of animals, as well as the destruction of our earth.

I know all about it, I read Diet For a New America 20 years ago, did not fall off the turnip truck just yesterday. ;-) I understand where you are coming from though, that's why I told the previous poster it depends on who you ask. Certainly a vegan in the real sense of the word is different than one who is just following a plant-based only diet.

cheers!
