Titanium dioxide remains in many food products in this country because of regulatory folly by the Food and Drug Administration, which allows problematic food ingredients to remain undetected and unreviewed.

Titanium dioxide goes into many industrial and consumer products. It makes paper white and bright, it keeps plastics and rubber soft and flexible, and helps remove harmful emissions from car exhaust, among many other uses. In the drug industry, it's a key ingredient in pill capsules and tablet coatings to keep the medicine inside from being affected by sunlight.
