Nanotechnology has found its way to the food supply. Iron and zinc nanoparticles so small that it takes a thousand of them to approximate a paper thickness can be added to foods like banana nano-smoothies to combat anemia or zinc deficiency.
Not only can nanoparticles fortify food, they can can extend food shelf life, change food flavors, and help monitor contamination. Nanotech is being used in cosmetics, paints, biotech, and now food. Banana nano-smoothies and other nano-foods have the potential to improve health around the world.
