separsons writes "Researchers are altering foods at the nanoscale level, changing their tiny molecular structures to enhance certain properties. (New Scientist has a more detailed look.) For example, one group of scientists found a way to hide water within individual droplets of oil, making low-fat mayonnaise taste like the real thing. The process can make spices spicier, potato chips healthier, and make diet food taste just like full-calorie snacks. Nanotech can even help combat global malnutrition. But the process is certainly controversial, and food manufacturers are being tight-lipped about exactly what nanofoods they're working on. So can nanotech create a healthier world, or is it just frightening Franken-food?"
