Daytime television’s self-promoting “YOU Doc” Dr. Mehmet Oz entertained us Wednesday with his assault on meat and dairy, offering up his talk show's couch to a vegan activist group that twists medical research to claim non-tofu proteins come with major health risks.

In typical Oz fashion, he promised to tell his audience what they “need to avoid in order to avoid getting cancer and heart disease.” And who better to fill everybody in than Neal Barnard?

Groan.

Barnard, for the unfamiliar, is president of the PETA-linked “Physicians Committee” for Responsible Medicine (PCRM), which gets most of its funding from a single wealthy animal-rights activist in Florida. Barnard, who has called cheese “dairy crack” and tried to sue milk companies for causing “pain and suffering” to lactose intolerant Americans, predictably railed against non-PETA-approved diets.

Oz promoted his guest’s agenda as “a different way of thinking about what you do in your day-to-day life.” Yes, we suppose that’s true. Barnard’s past claim that “to give a child animal products is a form of child abuse” is certainly, um… different. And Oz never told his audience that Barnard (a non-practicing psychiatrist) was once the president of the PETA Foundation—the organization that owns PETA’s office building and pays its salaries.

Oz helpfully suggests, “Don’t call it a diet.” And he’s right. Barnard’s advice is animal-rights ideology on a plate.

Eating nutrient-rich vegetables and fruits is a great idea, but so is eating nutrient-rich animal products. It’s difficult to swallow a stealthily masked, ideology-fueled prescription when it’s passed off as a cancer cure-all.

Has the good doctor (Oz, not Barnard) been fooled or is he a willing accomplice?
