Mozzarella, mayo and chewing gum: additive E171 is said to be carcinogenic

Is an additive in our carcinogens? There are currently over 300 authorized additives in the European Union. These are subject to strict regulations and may only be used after explicit approval. Each of these substances is assigned a specific E number, including the additive "titanium dioxide ". He has identification number E 171 . A new study suspects the substance in many foods to cause inflammatory bowel disease and also colon cancer


Risk of colorectal cancer: Premature titanium dioxide in more than 900 products

The component "titanium dioxide", also called E 1

71, is an oxide of titanium. It acts as a white cream and is used in products such as chewing gum, mayonnaise, mozzarella or cough sweets. In total, there should be more than 900 products where E 171 occurs. It is added in the form of small nanoparticles and is previously considered chemically stable and non-toxic. An English-language specialist magazine has now taken a closer look at the risks that the ingredient still entails.

Test with mice: The study shows the effects of the additive E171

According to the magazine "Limits in Nutrition", researchers have administered the additive to certain Muses and observed what effect this had on Museens' so-called gut microbiota. Intestinal microbiota means microorganisms that colonize the intestines of humans and animals.

The result of the study shows that the nanoparticles of titanium dioxide interacted with the gut bacteria. Intestinal function is impaired and inflammatory bowel disease may develop

Study leader: Evidence of increased risk of colorectal cancer from food with titanium dioxide

Study leader Wojciech Chrzanowski comments the results as follows: "This study provides Core evidence shows that food consumption with the additive E171 (titanium dioxide) affects both intestinal flora and intestinal inflammation which can lead to conditions such as inflammatory bowel disease and colon cancer. "

] The delivery of E 171 formed a biofilm in the intestines. A biofilm is different bacteria that stick to each other. According to prof. Laurence Macia also produces such a film in colorectal cancer and can therefore be a potential trigger for it.

Although the subject is approved, critics believe that the nanoparticles are still poorly understood ] have been. They are accused of triggering diseases such as dementia, asthma, eczema, autism and even cancer metastasis.

Consequences: Research requires further studies – Ban on the additive E171?

"The goal of this research is to stimulate debate on new standards and regulations to ensure the safe use of nanoparticles in Australia and around the world," said the researcher of the researcher. Thus, they do not specifically argue for a ban, but rather for the intensification of research when it comes to dealing with nanoparticles.

In Germany no ban is planned unlike in France. In our neighboring country, the dye E 171 will be banned from January 1, 2020.

E171 is "probably carcinogenic"

Experts from the European Chemicals Agency's Risk Committee (RAC) distinguish whether it consumes when the additive E171 is intermediate, absorbed through the skin or inhale. In the case of inhalation (inhalation), RAC occupied titanium dioxide as a hazardous substance by reference "presumably carcinogenic to inhalation" .

The available data on oral ingestion is currently not an indication of health problems for consumers, according to the European Food Safety Authority. However, no acceptable daily intake of the additive can be read at the moment, since particular effects on fertility and on unborn children have not been adequately investigated.
