Canned soup, boxed mac & cheese, breakfast bars, and queso--packaged foods containing titanium dioxide--against a background of the powdered white substance.

Titanium dioxide

Titanium dioxide (TiO2) is a color additive currently approved for use in the U.S. in human food, drugs, cosmetics (e.g., sunscreens), and medical devices (e.g., contact lenses). Based on evidence that TiO2 nanoparticles present in food-grade titanium dioxide can accumulate in the body and cause DNA damage, CSPI rates titanium dioxide as “Avoid”.
