For years scientists have raised concerns about the potential toxicity of titanium dioxide.

Potential hazards of oral exposure to TiO₂ NPs 

That came after a 2021 report from an expert panel at the European Food Safety Authority, which reviewed data on titanium dioxide safety. The panel said it couldn’t rule out concerns that the food additive might be able to damage DNA and possibly lead to cancer. They explained that after you eat something that has titanium dioxide in it, your body absorbs low levels of its particles – but the particles can build up as you eat more foods with this additive.

In a 2022 study published in the Journal of Hazardous Materials, scientists wanted to examine the effects of titanium dioxide as a food additive on atherosclerosis in mice. (Atherosclerosis refers to a hardening of the arteries.) Researchers fed mice 40 mg/kg of the food additive every day for 4 months, and found that it not only altered gut microbiota but also led to a significantly increased atherosclerotic lesion area, especially in animals that consumed a high-choline western diet (HCD).

People eating lots of candy should be more worried about the sugar and how it can cause high blood pressure and obesity, says Westerhoff.

This work confirms previous studies that show P-25 and other untreated anatase 377 nanoparticles should not be employed in sunscreens because the toxicity of P25TiO2NPs under UV radiation is significant.
