A new peer-reviewed article by a team of 15 scientists based in Mexico sheds light on the toxicity of a popular food additive often used as a whitening pigment.
The article, published in the journal Toxicology in August 2022, “Food Grade Titanium Dioxide Accumulation Leads to Cellular Alterations in Colon Cells After Removal of a 24-Hour Exposure,” examines the effects of titanium dioxide on cells.
The Mexican researchers found that so-called food-grade titanium dioxide, which is used as an additive in everything from candy to sunscreen, accumulated in colon cells, causing what may be permanent damage.
Using electron microscopy, the researchers identified the presence of food-grade titanium dioxide (TiO2) in a human colon cancer cell line that they maintained in a cell culture medium….
