The radical organization whose supposed mission is to protect animal welfare now says that cow milk not only worsens autistic symptoms but can actually cause autism too. PETA’s campaign to stop people from using animal products latched on to obscure studies of dietary influences on autistic symptoms. A PETA blog post refers to two studies that found a link between autistic children’s behavior and consumption of cow milk (or proteins found in cow milk), and jumps to conclude that "dairy foods may worsen or even cause autism.”
