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 flavours,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 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...read more>>>...
