Titanium dioxide (TiO2) is a naturally occurring compound that is mined, refined and processed into a fine powder. It is known for its exceptional opacity, brightness and high refractive index, making it an ideal ingredient in paint formulations. When added to paint, titanium dioxide scatters and reflects light, creating vibrant, long-lasting colors. It is this unique property that makes titanium dioxide the most widely used white pigment in the coatings industry.

  • Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”
