toxic nanoparticles

When you bite into fresh produce, are you also biting into health-damaging silver particles? Apparently — I’m not even making this up — no one really knows. Some 1,000 foods currently on the market are nanotechnology based, and there’s no question that such contaminants can damage human health. Now new research points to methods that could help identify these toxic nanoparticles on our food, so we can know whether or not to (continue?) eating them. Great news, or disturbing wake-up call?
