Nanofoods

From the website CHOICE: Trusted information for Australian consumers: Nanotechnology and food

”Nanofoods” refers to all foods to which manufactured nanoscale food components have been added and/or packaged in materials to which manufactured nanoparticles have been added. Nanotechnology certainly offers exciting possibilities for the future, such as safer food that can be conveniently stored for longer periods without deterioration. Other possibilities include foods fortified with healthy ingredients such as vitamins, antioxidants or omega-3 fats, encapsulated so that they are delivered exactly where they are needed in your body.

The main issue around regulation is not the small size of nanoparticles as such, rather their novel properties. We’ve always been exposed to naturally occurring nanoparticles, but never before to nanoparticles specifically manufactured to influence food properties. We simply do not yet know enough about how they could affect human health; no one predicted, for example, that carbon nanotubes could cause cancer ....
