Here is a wikipedia definition of dimethypolysiloxane. Notice it’s multiple uses…

Siloxanes can be found in products such as cosmetics, deodorant, water repelling windshield coating, food additives and some soaps. They occur in landfill gas and are being evaluated as alternatives to perchloroethylene for drycleaning. Perchloroethylene is widely considered environmentally undesirable.
Polymerized siloxanes with organic side chains (R ? H) are commonly known as silicones or as polysiloxanes. Representative examples are [SiO(CH3)2]n (dimethylsiloxane) and [SiO(C6H5)2]n (diphenylsiloxane). These compounds can be viewed as a hybrid of both organic and inorganic compounds. The organic side chains confer hydrophobic properties while the -Si-O-Si-O- backbone is purely inorganic. Dimethylpolysiloxane is added to vegetable oil as an antifoaming agent. McDonalds uses this type of vegetable oil to cook certain products[2]. In addition, automobile ignition modules, which heat up during use, dissipate heat by having their backings coated with Dimethylpolysiloxane (also known as a “thermo grease”). Acting as a “thermo grease” in this application, Dimethylpolysiloxane allows high heat transfer between the transistor ignition module and the distributor backing plate that it is mounted on which effectively cools the switching transistor (ignition module) during operation which enhances and extends its useful life. (There are some discussions expressing uncertainty about “di-electric grease” (in general) for this ignition application but they all do not have equal properties in simultaneously conducting heat well yet also remaining electrically non-conductive. Dimethylpolysiloxane has this property and may be considered falling into the category of a “di-electric grease” though properties vary for substances in this group.

GZ… That’s really interesting. I was very fortunate, or unfortunate depending on how you view it, to grow up in a catholic elementary school system. All the food there was real, not made from powder and what not. From middle school on, I was in the public system, and the food was crap. Made me feel like crap, too. Jamie Oliver knows what he’s talking about.

And yes, I will never doubt you and your street meat from now on, Rebecca.

Mmmm plastic-nuggety goodness. Should have gone with my street-meat suggestion that night, seems like the lesser of two evils now.

First…Chickens don’t have nuggets. ’nuff said.
Second…Check out Jamie Oliver’s website regarding school dinners in the UK…he’s got a whole section of ‘nuggets.’

Third…McDonald’s, unfortunately, is the best and most accurate representation of American food I can find in GZ…seriously. Every other restaurant is sort of close…but McD’s is it.
