Your Dairy Products Could Be Full of Nano-Metals

Today brings us another unwelcome addition to the list of things you wish weren’t in your food but that almost certainly are. This time, it’s “microscopic pieces of metal” in your dairy. Tom Philpott waded through the Project on Emerging Technologies’ list of nano consumer products and found 96 foods, most of them on the dairy aisle, with unlabeled nanoparticles like titanium dioxide, an ingredient Dannon uses to make Greek yogurt whiter and Kraft slips into American Cheese singles as an “anticaking agent.” But are these tiny particles really a big deal? Well, maybe. The problem is that even if producers know what these things do to food, nobody seems quite sure what, if anything, they do to us. [Mother Jones]
