Petroleum Products in American Mcnuggets, But Not British

A blog-posting and follow-up investigation lead by news organization CNN has lead to the renewed debate about the role of chemistry in fast food. Originally reported in "The Omnivore's Dilemma," the American McDonald's McNugget contains small amounts of a petroleum-based chemical. The British McNugget, however, according to the CNN study, does not. It's also less fattening.
From CNN: "American McNuggets (190 calories, 12 grams of fat, 2 grams of saturated fat for 4 pieces) contain the chemical preservative tBHQ, tertiary butylhydroquinone, a petroleum-based product. They also contain dimethylpolysiloxane, "an anti-foaming agent" also used in Silly Putty."
The FDA allows the use of such chemicals in small doses, and according to another chemistry blog, the notion that Chicken McNuggets could kill you is a bit overblown.
"I don't know whether we should be eating high quantities of preservatives in our food, but this is just scaremongering," on the Scienceblogs.com site Molecule of the Day in 2007.
"A nugget containing the claimed maximum, 0.02 percent, would require you to eat 5kg to attain a TBHQ dose of 1 gram. A 20-piece order has a mass of 320g. A maximally-preserved batch of nuggets would require one to eat 312.5 nuggets (13,125 kcal/54,915 kJ) to obtain this dose. I enjoy the occasional ultra-processed nugget, but they aren't that tasty."
