While we love a good jam sesh every now and again, over at Because Health when we talk heavy metal, we're getting our periodic tables out, pulling on the lab coats, and talking about elements like arsenic, mercury, lead, and cadmium. Although these are naturally occurring elements, scientists have learned that they can cause some pretty negative health effects.

Side note, not all metals are bad for humans. In fact, there are even some that we need in order to stay healthy, like iron, zinc, and magnesium. So, just because it sounds like a metal it doesn't mean it's dangerous. You just have to be careful about some of them. But have no fear, we lay out the big names to stay away from here.
