Nanoparticles in Food (like titanium dioxide) Found in Blood Stream: Effects in Question

Study Looks at Particles Used in Food. Stephanie Strom Published: February 5, 2013

[Excerpted] Nanomaterials, substances broken down by technology into molecule-size particles, are starting to enter the food chain through well-known food products and their packaging, but there is little acknowledgment by the companies using them, according to a new report from a nonprofit group that works to enhance corporate accountability. 

Some companies may not even know whether nanomaterials are present in their products, the corporate accountability group As You Sow said.

...Their small size allows nanoparticles to go places in the body where larger particles cannot and enter cells. They have been found in the blood stream after ingestion and inhalation, and while research on their health effects is limited, studies have shown them to have deleterious effects on mice and cells.

Majia here: The Group As You Sow tested powdered doughnuts for nanoparticles and found titanium dioxide them in 10 varieties. The article reports that the EPA is investigating the safety of titanium dioxide, which is used to make white brighter.
