Nanoparticles, clandestine passengers in candy

Nanoparticles, clandestine passengers in candy

The study carried out by the French magazine 60 millions de consommateurs analyzed the presence of the additive E171 or titanium dioxide, made up in part of nanoparticles and frequently used in the food and cosmetic industry to whiten candies, prepared dishes and toothpastes.

For the magazine, published by the National Institute of Consumer Affairs, which is presented in the form of nanoparticles –50 thousand times smaller than a hair–, raises questions about health because it more easily crosses physiological barriers.

When a foreign substance gets inside a cell, we can assume that there may be damage or, in any case, a disorder of some of these cells, explained Patricia Chairopoulos, co-author of the study, who reproaches the industrialists for lack of vigilance and rigor .

Chocolates, lunettes and cookies:

Of the 18 sweet products tested by the magazine, E171 was consistently found in the form of nanoparticles, although in varying proportions. In the Napolitain de Lu cookies, 12 percent of the additive E171 was detected in the form of nanoparticles, a percentage that rose to 20 in the M & M's chocolates and 100 percent in the Monoprix Gourmet brand cookies.

The presence of E171 is indicated on the labels, but without the mention of nanoparticles. Chairopoulos highlighted that a study published in January by a French institute raised suspicions about this additive in nano form, concluding that chronic exposure to E171 favored the growth of precancerous lesions in rats, without extrapolating this risk to humans.

In June 2016, the NGO Agir pour l’environnement warned of the presence of nanoparticles, including titanium dioxide, in numerous food products.
