Casein [the main protein found in dairy], in fact, is the most 'relevant' chemical carcinogen ever identified; its cancer-producin g effects occur in animals at consumption levels close to normal-striking ly unlike cancer-causing environmental chemicals that are fed to lab animals at a few hundred or even a few thousand times their normal levels of consumption.
