Faber argued there hasn't been enough change in these federal regulations in the decades following the FDA's approval of titanium dioxide – especially as others increasingly point to potential health consequences.

How do I know if a Unilever product contains titanium dioxide?

In industrial settings, people can be exposed to titanium dioxide through inhalation. Inhalation exposure to titanium dioxide is exceedingly rare for most people. 

By reducing processed foods in your diet, you can reduce the likelihood of not only eating titanium dioxide but eating other chemicals of concern, Faber said, noting that consumers can also call their elected representatives urging them to support increased food safety legislation and take action with organization alliances like Toxic Free Food FDA. America, once again, is falling behind the rest of the world when it comes to chemical safety.
