Of course Dr. Neal Barnard is busy trying to prove a half-baked “addiction” theory about meat and dairy foods [“The seductive quality of food is all in the brain,” Nation, Sunday]. What do you expect from a professional animal rights activist?

That’s right. Dr. Barnard’s misnamed Physicians Committee for Responsible Medicine [PCRM] is not a legitimate research group. It’s a front group for People for the Ethical Treatment of Animals [PETA]. Dr. Barnard is one of three people on the board of the PETA Foundation. PETA has used this foundation to funnel nearly $600,000 of its tax-exempt money to PCRM. The two organizations share offices, staff and financial accounting as well. The animal rights watchdog newspaper Animal People News calls them “a single fundraising unit” and accuses them of attempting to “evade public recognition of their relationship.”

Dr. Barnard and his meat-is-evil message are dangerous. Don’t take my word for it, though: The American Medical Association has called the physicians committee a “pseudo-physicians group” and considers its recommendations “irresponsible and potentially dangerous to the health and welfare of Americans.” The Physicians Committee for Responsible Medicine has been formally censured by the American Medical Association.

Most Americans are too smart to take dietary advice from animal rights zealots, but when radicals put on the sheep’s clothing of the medical profession, it becomes harder and harder to know who’s credible.
