Metal oxide nanoparticles \u2013 commonly used as food colouring and anti-caking agents in the commercial ingredients industry \u2013 may damage parts of the human intestine, according to new research by Cornell and Binghamton University scientists.<\/h3>\n

<\/p>\n

\u201cWe found that specific nanoparticles \u2013 titanium dioxide and silicon dioxide \u2013 ordinarily used in food may negatively affect intestinal functionality,\u201d said senior author Elad Tako, associate professor of food science at Cornell. \u201cThey have a negative effect on key digestive and absorptive proteins.\u201d<\/p>\n

In their research, the group used human-relevant doses of titanium dioxide and silicon dioxide in the Tako laboratory\u2019s in vivo system, which offers a health response similar to the human body\u2019s.<\/p>\n

The scientists injected the nanoparticles in chicken eggs. After the chickens hatched, the scientists detected changes in the functional, morphological and microbial biomarkers in the blood, the duodenum (upper intestine) and the cecum (a pouch connected to the intestine).<\/p>\n

\u201cWe are consuming these nanoparticles on a daily basis,\u201d said Tako. \u201cWe don\u2019t really know how much we consume; we don\u2019t really know the long-term effects of this consumption. Here, we were able to demonstrate some of these effects, which is a key to understanding gastrointestinal health and development.\u201d<\/p>\n

Despite the finding, the scientists are not yet calling for an end to the use of these nanoparticles.<\/p>\n

\u201cBased on the information, we suggest simply being aware,\u201d Tako said. \u201cScience needs to conduct further investigations based on our findings. We are opening the door for discussion.\u201d<\/p>\n

The research is published in the 9 February 2023 issue of Antioxidants. https:\/\/doi.org\/10.3390\/antiox12020431<\/a><\/p>\n<\/div><\/section>
