What we know and don't know about the impacts of proliferating nanoparticles in our food supply.
THE INCREASING PRESENCE OF NANOPARTICLES IN OUR FOOD SUPPLY
On the surface, nanoparticles seem to offer many potential benefits. By adding them to foods and food packaging, they can help deliver nutrients, act as thickening agents, enhance taste or flavor or ensure longer freshness of food. But because of their microscopic size, these minute versions of silver, zinc, titanium dioxide and other metals and nutrients, may cause adverse health impacts. Scientists are still determining the health and environmental impacts of these tiny particles, yet industry is forging ahead introducing nanoparticles into a wide array of packaged foods and food packaging.
