New York, - A common food additive found in chewing gums, chocolates and breads may significantly reduce the ability of small intestine cells to absorb nutrients and block pathogens, a new study has warned.
"Titanium oxide is a common food additive and people have been eating a lot of it for a long time, but we were interested in some of the subtle effects, and we think people should know about them," said Gretchen Mahler, a Professor at the Binghamton University in the US.
"There has been previous work on how titanium oxide nanoparticles affects microvilli, but we are looking at much lower concentrations," Mahler said. "We also extended previous work to show that these nanoparticles alter intestinal function", she said.
Titanium dioxide is generally recognized as safe by the US Food and Drug Administration and ingestion is nearly unavoidable. The compound is an inert and insoluble material that is commonly used for white pigmentation in paints, paper and plastics.
