If you’re like most Americans, you’ve grown up thinking you need to consume dairy to stay healthy. You subscribe to the idea that milk does a body good because that’s what dietary guidelines tell you. Plus, you need milk and other dairy products to build strong bones, right? Confession: That was once me. I grew up having milk at every meal. And cheese? Sign me up, especially if it meant pizza was involved. Even when I began venturing into veganism as an adult, I held onto dairy. My rationale: Wasn’t I supposed to eat dairy, and how could it be harming animals?
