A human's small intestine has its natural way of combating pathogens. However, with the presence of a food additive found in usual junk foods, the titanium dioxide, it decreases this natural ability of the small intestine.
A research from Binghamton University, State University of New York created an experiment where a small intestinal cell structure model was exposed to a diet filled with titanium oxide. The experiment had set ups which showed an acute exposure which is equivalent to four hours and a chronic exposure which is synonymous to a five-day exposure, according to Physics.
Assistant Professor Gretchen Mahler, one of the authors of the study, explained in an interview with Science Daily that titanium oxide is actually a common food additive for processed foods such as candies, chocolates, and doughnuts. Mahler immediately said that titanium oxide definitely won't kill anyone. Their team is only interested what are the effects of this food additive in the digestive system especially that it is usually in the food people eat nowadays.
Mahler also explained that despite having no detrimental effects, people should be aware that titanium oxide and dioxide as an additive can actually affect the cells in the intestine especially if exposed chronically. These cells also known as "microvilli" act as barriers which helps in the metabolism. However, with a large exposure to this food additive, it lessens the microvilli count weakening metabolism and increasing risks of inflammation.
The US Food and Drug Administration (FDA) acknowledges the safety of titanium dioxide and also states that ingestion is indeed unavoidable. This food additive is usually used in chocolates for its smooth and creamy texture. It is also used in doughnuts to add more attractive colors, and even in toothpastes which gives off some abrasive texture needed for cleaning.
