How do you fancy tucking into a bowl of ice cream that has no more fat than a carrot? Or eating a burger that will lower your cholesterol? If you are allergic to peanuts, perhaps you'd like to fix your food so that any nut traces pass harmlessly through your body. Welcome to the world of nanofoods, where almost anything is possible: where food can be manipulated at an atomic or molecular level to taste as delicious as you want, do you as much good as you want, and stay fresh for ... well, who knows? A world where smart pesticides are harmless until they reach the stomachs of destructive insects; where food manufacturers promise an end to starvation; where smart packaging sniffs out and destroys the micro-organisms that make good food go bad. In short, a food heaven to those who see it spelling the end of obesity and poor diet. Food hell to those who believe the case for nanofood safety is still far from proven. One thing is certain: after the controversy that surrounded genetically modified foods, nano is set to become the next kitchen battleground.
Nanotechnology has its roots in a talk delivered in 1959 by physicist Richard Feynman to the American Physical Society. He predicted a time when individual atoms and molecules might be used as the building blocks for a set of tools that could then make a smaller set, and so on. The scale he was talking about strains the imagination. A nanometer - nm - (from the Greek word nanos, dwarf) is one-billionth of a metre. To help you visualise how small that is, a red blood cell is about 7,000nm across, a human hair 80,000nm wide and a water molecule slightly less than 0.3nm in diameter. The science of nanotechnology generally inhabits the region of 0.1nm to 100nm.

One thing for sure - it'll bring the whackjobs out of the woodwork.
