Particles of titanium dioxide (TiO2) are one of the nanomaterials most frequently found in everyday consumer products, including foods. TiO2 has long been considered a safe food coloring and is thus not eliminated by the Feingold Diet. In recent years, however, TiO2 has quietly changed its format to nanoparticles. Their extremely small size allows these nanoparticles to cross biological barriers and potentially lead to adverse health effects.
TiO2 nanoparticles cross the placental barrier and are found in the human placenta and in the infant meconium. Although chronic exposure during pregnancy is known to induce offspring cognitive deficits associated with neurotoxicity, its impact on breathing specifically has not been tested until now.
In this study, the authors show that maternal exposure to TiO2 nanoparticles during pregnancy affects the normal development and operation of the respiratory centers in the offspring. Not only is their breathing rate elevated, but they seem to be unable to adjust it in response to environmental cues such as changes in temperature.
NOTE: No mention is made of any possible connection between prenatal exposure to TiO2 nanoparticles and SIDS, but one can’t help but wonder.
