"Nanomaterials are often heralded as having the potential to revolutionize the food industry – from enabling the production of creamy liquids that contain no fat, to enhancing flavors,improving supplement delivery, providing brighter colors, keeping food fresh longer, or indicating when it spoils. It is reported that nanotechnology is already used in food and food related products, but due to lack of transparency about the issue, concrete information has been difficult to obtain.
Because of their small size, nanoparticles are able to go places in the body that larger particles cannot. Nanoparticles in food or food packaging can gain access via ingestion, inhalation,or skin penetration. When ingested, the nano-sized particles facilitate uptake into cells and can allow them to pass into the blood and lymph where they circulate through the body and reach potentially sensitive target sites such as bone marrow, lymph nodes, the spleen, the brain, the liver, and the heart. Nanoparticles penetrating the skin can distribute through the body via lymphatic channels. Inhaled nano TiO2 [Titanium dioxide - music] has been found to act like asbestos and silicone in that it accumulates in the lung and causes inflammation and can impact DNA proteins and cell membranes."
"A Swedish study, Influence of Nanoparticles on Blood-Brain Barrier Permeability and Brain Edema Formation in Rats, revealed that nanoparticles derived from transition metals, silver, copper, aluminum, silicon, carbon and metal oxides easily crossed the blood-brain barrier and produced lasting damage to the barrier, by altering the permeability"
"...it isn’t known exactly how nanoparticles will affect humans. They have been shown to cause altered gene markers and brain damage in fish, accumulation in laboratory animals, and at least one type of nanoparticle has been shown to cross the human placenta in preliminary studies."
"Ironically, the FDA also refuses to say that the nanoparticles are safe. “At this time, we are not aware of any food ingredient or [food contact substance] intentionally engineered on the nanometer scale for which there are generally available safety data sufficient to serve as the foundation for a determination that the use of a food ingredient or [food contact substance] is GRAS.” (GRAS = Generally Recognized As Safe)"
