An investigation by CNN has uncovered that American chicken McNuggets contain the ingredient dimethylpolysiloxane, “an anti-foaming agent” also used in Silly Putty. They also contain a petroleum-based chemical preservative known as TBHQ, tertiary butylhydroquinone.
British McNuggets, on the other hand, don’t contain either ingredient and are generally less fatty because the Brits prefer their nuggets cooked then coated while the Americans prefer the opposite.
While studies show that both ingredients do not pose any health risks in small doses (apparently, one gram of TBHQ can cause “nausea, vomiting, ringing in the ears, delirium, a sense of suffocation, and collapse,” according to “A Consumer’s Dictionary of Food Additives.” Eh, no big deal. ), the fact that they exist in our nuggets may be off-putting to some. Others may go out and buy Silly Putty to see if it tastes like McNuggets.
