Does the titanium dioxide in food and nanomaterials affect the gut microbiome?

New Rochelle, NY, Oct. 3, 2017 — A new study has shown that the titanium dioxide (TiO2) frequently used in foods, coatings, pigments, and paints that is ingested can affect both the types of bacteria present in the human gut and the pH of the colon. The physical and chemical properties of two forms of TiO2 studied appear to produce different microbial responses, according to an article published in Environmental Engineering Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Environmental Engineering Science website until November 3, 2017.

In the article entitled "Food and Industrial Grade Titanium Dioxide Impacts Gut Microbiota ," coauthors Travis Waller, Chen Chen, and Sharon Walker, University of California, Riverside, report results of studies in which they exposed a laboratory model of the human colon to either food- or industrial-grade TiO2 particles. The researchers looked for changes in the human gut microbiota and, in particular, differing affects on the microbial community structure, phenotype, and cellular function as evidenced by the bacteria's ability to degrade various substances.

"As we increasingly use technology to improve our lifestyles, we must consider associated consequences that may not have been foreseen. This important paper explores some of the impacts of widespread use of TiO2 in food and other engineered products that may find their way into our digestive systems. Waller et al. show that TiO2 that finds its way into our gut may not be without ramifications," says Domenico Grasso, PhD, Editor-in-Chief of Environmental Engineering Science and Provost, University of Delaware, Newark.
