Andrew Maynard, director of Risk Science Center at the University of Michigan, rejected the supposed danger from use of titanium dioxide in food. He says that the titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it is not a nanomaterial either. Nanoparticles are typically smaller than 100 ...
Studies on aluminum nanoparticles and titanium nanoparticles indicate that they are explosion hazards. [ 5 ] : 17–18 One study found that the likelihood of an explosion but not its severity increases significantly for nanoscale metal particles, and they can spontaneously ignite under certain conditions during laboratory testing and handling.
Titanium dioxide has been found to be toxic to plants and small organisms such as worms, nematodes, and small arthropods. [22] The toxicity of TiO 2 nanoparticles on nematodes increases with smaller nanoparticle diameter specifically 7 nm nanoparticles relative to 45 nm nanoparticles, but growth and reproduction are still affected regardless of ...
In the study, rats that ingested titanium dioxide every day showed signs of a flared-up immune systems and pre-cancerous lesions. (Don’t miss these other 8 cancer-causing foods you should stop ...

Nanoparticles can be divided into combustion-derived nanoparticles (like diesel soot), manufactured nanoparticles like carbon nanotubes and naturally occurring nanoparticles from volcanic eruptions, atmospheric chemistry etc. Typical nanoparticles that have been studied are titanium dioxide, alumina, zinc oxide, carbon black, carbon nanotubes ...
According to the NOVA classification system, ultra-processed foods are industrial formulations made entirely or mostly from substances extracted from foods (oils, fats, sugar, starch, and proteins ...
An example of this has occurred in the US, and involves nanoparticles of titanium dioxide (TiO 2) for use in sunscreen where they create a clearer cosmetic appearance. In this case, the US Food and Drug Administration (FDA) reviewed the immediate health effects of exposure to nanoparticles of TiO 2 for consumers.
