Researchers at institutions such as Binghamton University reported in a new academic journal, Nano-Influence, that they used small intestine cells cultured in the laboratory to simulate the effects of titanium dioxide particles of about 30 nanometers in diameter on the intestines. . For example, in 4 hours, the intestinal cells are exposed to the amount of titanium dioxide particles contained in one meal to simulate acute contact; in 5 days, the intestinal cells are exposed to the equivalent of 3 meals. The amount of titanium dioxide particles to simulate the situation of chronic contact.
It was found that acute contact does not cause any changes, but chronic long-term exposure can cause the reduction of the micro-villi on the surface of the small intestine cells, thereby impairing the antibacterial barrier of the digestive system, reducing the rate of digestion, and affecting iron, zinc, fatty acids, etc. The absorption of nutrients, in addition to the indications of inflammation has also increased.
Titanium dioxide, also known as titanium dioxide or titanium sugar, is a common food additive that the US Food and Drug Administration considers to be safe. It is often added to toothpaste, chocolate to add texture, or used in foods such as doughnuts and skim milk to make them look brighter and more attractive. In addition, it is widely used as a white pigment in paints, papers and plastics, and is also added to sunscreens to protect against UV rays.
Researchers at Arizona State University in the United States tested 89 common foods such as chewing gum, creamy cakes and mayonnaise in 2012 and found that they contained titanium dioxide.
Grekin Mahler, an assistant professor of biomedical engineering at Binghamton University, one of the authors of the study, said: "To prevent the intake of too much titanium dioxide particles, it is best to avoid eating deep-processed foods, especially candy."
