                                Nanoscale materials are not new to the human diet, with many foods naturally containing particles invisible to the naked eye. A prime example of a natural nano food is milk, which contains protein and mineral clusters called casein micelles. These tiny particles perform an important biological function, and humans have consumed them safely for millennia.
