According to the McDonald's Corporation, its famous Chicken McNuggets are made with ingredients including autolyzed yeast extract (which contain free glutamate, similar to MSG), sodium phosphates and sodium aluminum phosphate. But that's not the freaky part. According to McDonald's own website, Chicken McNuggets are also made with "hydrogenated soybean oil with TBHQ and citric acid added to preserve freshness" and "Dimethylpolysiloxane added as an antifoaming agent." (http://nutrition.mcdonalds.com/nutr...)
At least two of these ingredients are artificially synthesized industrial chemicals. TBHQ, a petroleum derivative, is used as a stabilizer in perfumes, resins, varnishes and oil field chemicals. Laboratory studies have linked it to stomach tumors. "At higher doses, it has some negative health effects on lab animals, such as producing precursors to stomach tumors and damage to DNA. A number of studies have shown that prolonged exposure to high doses of TBHQ may be carcinogenic, especially for stomach tumors." (http://en.wikipedia.org/wiki/TBHQ)
Dimethylpolysiloxane, a type of silicone, is used in caulks and sealants, as a filler for breast implants, and as key ingredient in Silly Putty.
Anti-foaming agent? Again. Eeeewwwwww. I don't even want to know what's in the dipping sauces.
