Frontiers - Nanofoods

Sue Broom talks to the food industry and academics who are making use of the quirky physical laws of the extremely small to create 'nano foods'. Scientists are able to manipulate particles at the nano scale, changing the way that food tastes and feels, and even improving its nutritional content. Sue examines whether or not nanoparticles are safe to eat, and considers what impact, if any, they might have on the environment.
