… Unbeknownst to just about everyone, nanoparticles made a quiet entrance into the nation’s food supply at least a decade ago. Nanoparticles are materials that are microscopic—significantly smaller than a red blood cell; and tens of thousands of times smaller than the width of a human hair. These particles can help deliver nutrients, ensure longer freshness of food, act as thickening agents or enhance taste or flavor. The problem is, scientists are still determining the health and environmental impact of these tiny particles, even as industry is forging ahead.
… The FDA has been slow to catch up. In fact, the agency doesn’t even track which foods contain nanoparticles.
… Recent research found that foods with caramelized sugar, including bread and corn flakes, contain
carbon nanoparticles. Many nutritional supplements—or “nanoceuticals”—come equipped with copper, silver or iron nanoparticles.
… Then there are the nanoparticles that are not intended to enter the food supply, but because of their miniscule size slip through wastewater treatment in particle or dissolved form and take up residence in the biosolids created at the end of the wastewater treatment process.
