Titanium dioxide, an additive found in over 3,000 ultra-processed foods, can cause DNA damage and mutations, reported a recent study by a panel formed by the European Food Safety Authority (EFSA).

Published in May in the EFSA Journal, the review assessed hundreds of studies on the infamous food additive. The panel couldn’t determine a safe level of exposure to titanium dioxide, which led them to conclude that it is not safe for use in foods. The EFSA is currently reviewing the safety of other chemical additives used by the food industry.
