We have published myriad of scientific studies linking nanoparticles like titanium dioxide * to serious harm to the digestive system, including IBD, colitis and colon cancer. (See: Serious Digestive Problems Linked to Food Additive Titanium Dioxide.) Now, a new study examined the health effects of five such nanoparticle food additives. The results revealed that two commonly used food additives known as metal oxide nanoparticles–in particular, titanium dioxide and silicone dioxide-–can have negative effects on your gut health. 

What are these nanoparticles used for by food manufacturers? Titanium dioxide tends to show up as a whitening and brightening agent. Silicon dioxide tends to be added to foods to prevent it from clumping. Iron oxide tends to be added to meats to keep that red color. And zinc oxide can be used as a preservative because it is an antimicrobial.
