It looks like Washington mayor Tony Williams has caved under pressure from anti-milk activist Neal Barnard, nanny-in-chief at the Physicians Committee for Responsible Medicine (PCRM). The mayor wanted to recognize May 11 as “Drink Chocolate Milk Day” in order to encourage children to drink more milk. Williams is also scheduled to make a public appearance sporting a milk-moustache, as many celebrities have done in the very successful “Got Milk?” ad campaign. PCRM will have none of it, offering the unfounded claim that milk is linked to prostate cancer and diabetes.
