T. Colin Campbell grew up on a Virginia dairy farm, and came to consider milk “the nectar of life.” But after becoming a nutritional researcher, he changed his tune, and now says “it’s unnatural to drink milk.” Could this be because Campbell, who spread his anti-dairy views in a recent writeup in Discover, is president and CEO of Paracelsian — “a company that promotes holistic health and sells assays to measure dioxinlike chemicals and evaluate herbal products”?

Campbell is also a member of the Physicians Committee for Responsible Medicine (PCRM), whose president, Neal Barnard tells Discover, “It would be hard to imagine a worse vehicle [than milk] for delivering calcium to the human body.” Of course, the same article quotes Gregory Miller of the National Dairy Council noting that PCRM is “essentially an animal rights organization” — one that has been repeatedly denounced by the American Medical Association, the National Osteoporosis Foundation, the American Council on Science and Health, and others.

“People might think we’re nuts,” Campbell concedes. “But nondairy beverages and foods are pretty good once you adjust to the taste.”
