   In the food industry, nanotechnology is being investigated for its potential to improve taste, texture and shelf life. What happens to insoluble nanoparticles? If they can't be broken down and digested or degraded, can they accumulate and cause damage to organs?
   
   #1 - the USA bans the labeling of Frankenfoods - will Nanotech foods also be unlabeled by law?
   
   http://nano.foe.org.au/node/198 "nanotechnology will be used in 40% of the food industries by 2015....processed food with nano-encapsulated nutrients, its appearance and taste boosted by nano-developed colours, its fat and sugar content removed or disabled by nano-modification ... Mars Inc. already has a patent on an invisible, edible, nano wrapper which will envelope foods, preventing gas and moisture exchange ... carbon nanoparticles, have been found to cause brain damage in largemouth bass"
   
   Gee - makes pink slime look pretty damn good - or is that already 'nano-ed'?
   
   
   
   silicate nanoparticles to provide a barrier to gasses
   Zinc oxide nanoparticles to block UV rays
   
   Hey they are even messing with my beer! Clay nanoparticles are being used to prevent air from entering plastic beer bottles. AmBev & Corona beer makers use "Nansulate High Heat for thermal insulation and corrosion protection on an interchanger." - http://www.nanotechbuzz.com/50226711/be … nology.php
   
   25 Year Shelf Life! Oooh - I want that ... not!

   It sounds dodgy to me. I wouldn't want it, except we probably don't have a choice. It HAS to be labeled.

   Zinc oxide is a common component of cosmetics and ultimately ends up as a contaminant of solid waste generated by sewage treatment. This waste is widely used as an organic fertiliser. ...zinc oxide nanoparticles have been shown to be toxic to mammalian cells ....Soybean growth was significantly stunted when the plants were cultivated in the presence of high levels of cerium oxide nanoparticles.

   sunscreen has come under fire recently with the news that the zinc oxide and titanium dioxide in many sunscreen products can induce free radical formation in the presence of light and that this may damage these cells. Many dermatologists still say that the benefits of sunscreen outweight the potential negative effects of the spreading of cell damage caused by photo-mutagenicity with zinc oxide, especially for fairer skin people

   "... a class of nanoparticles being widely developed in medicine - polyamidoamine dendrimers (PAMAMs). In tests on cells in the lab, the researchers found the particles cause lung damage by triggering a type of programmed cell death known as autophagic cell death.
