Scientists Think A Common Ingredient In Toothpaste Could Cause Cancer

There is said to be an ingredient that is used in toothpaste and even a range of food products that contribute to cancer, scientists have found.

Scientists Think A Common Ingredient In Toothpaste Could Cause Cancer


Titanium dioxide, an additive, has caused nothing but pre-cancerous growths in 40% of rats that were given the water with the chemical in it, according to lead researchers in Luxembourg and France. It had even increased the growth speed , which aren’t said to be malignant but can quickly develop into a severe case of cancer. 
The product used is “E171” and its used in our chocolate, sweets, chewing gum and biscuits, as well as our toothpaste we use daily. It even is found in sunscreen, just for its whitening effect to look less transparent. There has been previous research conducted by the International Agency for Research on Cancer found in the inhalation of titanium dioxide, which is used mostly in paint, could cause cancer-but this is the first link to be shown when the chemical is consumed orally.
In a current study, scientist have seen that E171 had been absorbed into the intestine and passed through blood, where it will spread to various areas of the body. In 40% of the tested rats, precancerous growths were found in those who were exposed to the chemical, but none had any cancer growth when given uncontaminated water. The chemical is also found to destabilize the immune system in rats’.
Scientists aren’t sure if the product will have the same effect on humans, but they state that their findings “cannot be extrapolated to humans”. “In light of the findings of this study, the Ministries of Economy, Health and Agriculture decided to jointly refer the National Agency for Food, Environmental and Occupational Health Safety (Anses) to determine whether the food additive E171 presents a potential hazard to consumers.”

The Independent has tried to get in contact with the UK Department of Health for any comment(s). France’s National Institute for Agricultural Research (INRA) lead with their study, looking into the impacts of titanium dioxide in rats. It was published in the Scientific Reports journal.

The team of scientists handed rats E171 through their drinking water for 100 days. They used the same amount used in cosmetic products and foods human use and consume.

Published in their findings, the researchers stated: 

These results indicate that E171 both initiates and promotes the early stages of colorectal carcinogenesis in animals. These studies show for the first time that the additive E171 is a source of titanium dioxide nanoparticles in the intestine and the entire body, with consequences for both immune function and the development of preneoplastic lesions in the colon. Oral exposure to E171 is a concern, especially in children who tend to eat a lot of sweets.
