Some of our foods contain nano particles—should we be worried?

We choose to spend money on household items based on how they look, feel and taste, and how we think they might make our lives better.  Manufacturers apply nanotechnology—a field of technology that makes use of effects that happen at the nanoscale—to create the properties we want in such items. For example, whiteness in toothpaste, or preventing growth of bacteria in socks.  One nanometre is one billionth of a meter. Chemical and physical interactions at the nanoscale are way smaller than our eyes can see. Medicines, tiny sensors, fast computers and food science are all ways we can put nanotechnology to use.  But some people are concerned nanoparticles may present health risks. Recently France announced one nanoscale food additive will be banned from 2020 due to a lack of evidence about its safety.  Read more....
