In taking note of the anti-milk protest lodged against D.C. Mayor Anthony A. Williams by the Physicians Committee for Responsible Medicine, you left your readers with the impression that this organization is a serious source of public health wisdom (“Mayor shaves milk-mustache ideas,” May 3). Nothing could be further from the truth. The Physicians Committee is an animal-rights front group. Its goals are to abolish the use of animals as food (including milk and eggs) and to eliminate the use of animals for advancing science and medicine. The group’s president, Neal Barnard, co-chairs the multimillion-dollar Foundation to Support Animal Protection with People for the Ethical Treatment of Animals president Ingrid Newkirk.

The opinion of the American Medical Association is unequivocal, calling the Physicians Committee’s recommendations “irresponsible and potentially dangerous to the health and welfare of Americans.” In a separate public censure, the AMA’s board of directors mused on “how effectively a fringe organization of questionable repute continues to hoodwink the media with a series of questionable research that fails to enhance public health.”

The Physicians Committee for Responsible Medicine is an ideologically biased source of health information. Your readers should know that it dispenses potentially dangerous dietary advice, which is based on animal-rights doctrine rather than on sound nutritional science.
