Nanotechnology involves the design and manipulation of materials on molecular scales. Companies using nanotechnology say it can enhance the flavor or nutritional effectiveness of food. Food produced by using nanotechnology is quietly coming onto the market, and consumer groups want U.S. authorities to force manufacturers to identify them.
U.S. health officials generally do not place warning labels on products unless there are clear, known reasons for caution or concern. But consumer advocates say uncertainty over health consequences alone is sufficient cause to justify identifying nano-foods.
