All McNuggets not created equal

All McDonald’s   nuggets are not created equal.

U.S. McNuggets not only contain more calories and fat than their British counterparts, but also chemicals not found across the Atlantic.

CNN investigated the differences after receiving a  blog comment asking about them.

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.

By contrast, British McNuggets (170 calories, 9 grams of fat, 1 gram of saturated fat for 4 pieces) lists neither chemical among its ingredients.

“I would certainly choose the British nuggets over the American” says Ruth Winter, author of  “A Consumer’s Dictionary of Food Additives.”

McDonald’s says the differences are based on the local tastes: In the United States, McNuggets are coated and then cooked, in the United Kingdom, they are cooked and then coated. As a result, the British McNuggets absorb less oil and have less fat.

"You would find that if you looked at any of our core food items. You'd see little, regional differences," says Lisa McComb, who handles global media relations for McDonald's, which has more than 32,000 restaurants in 117 countries. "We do taste testing of all our food items on an ongoing basis."

One apparent difference is only a matter of labeling, according to McComb. U.K. McNuggets list ground celery and pepper, which are labeled simply as "spices" in the United States, she says.

Marion Nestle, a New York University professor and author of “What to Eat,” says the tertiary butylhydroquinone and dimethylpolysiloxane in the McNuggets probably pose no health risks. As a general rule, though, she advocates not eating  any food with an ingredient you can’t pronounce.

Dimethylpolysiloxane is used as a matter of safety to keep the oil from foaming, McComb says. The chemical is a form of silicone also used in cosmetics and Silly Putty.  A review of animal studies by The World Health Organization found no adverse health effects associated with dimethylpolysiloxane.

TBHQ is a preservative for vegetable oils and animal fats, limited to .02 percent of the oil in the nugget. One gram (one-thirtieth of an ounce) can cause "nausea, vomiting, ringing in the ears, delirium, a sense of suffocation, and collapse," according to “A Consumer’s Dictionary of Food Additives.”

In 2003, McDonald’s launched smaller, all-white-meat McNuggets after a federal judge dubbed the food “a McFrankenstein creation of various elements not utilized by the home cook." Among the ingredients that remained in the new McNuggets: tBHQ and dimethylpolysiloxane.

Christopher Kimball, the founder and publisher of Cook’s Illustrated magazine and host of the syndicated cooking show America’s Test Kitchen, says he suspects these chemicals are required for the nuggets to hold their shape and texture after being extruded into nugget-shaped molds.

“The regulations in Europe, in general, around food are much stricter than the U.S.,” Kimball says.

    Why doesn't McDonald's try and change America's loving relationship with bad food? They have pull, since so many eat their garbage.

      I love eating food, period, but I also excercise and drink lots of water. Anyone who eats the same food from the same source multiple times a week or month is an idiot. But I won't cut out a cheeseburger now and then (I prefer 5 Guys over anyone else) for fear of sodium overdose or death by chemical. Who wants to live like that? In constant fear that you're going to die because of what you put in your mouth? Besides, I don't want to get hit by a car and then have the first words I say to God in heaven – "damn, I knew I should of had that burger today".

    I have an idea, if you don't like McDonald's or what they put in their food, don't eat it. I usually don't comment on this stuff, but the stupidity and argumentative behavior of the posters lit a fire apparently. If you don't want that shit in your body, don't eat McDonald's or other foods you know are bad. And as others have said, you are going to die of something. Unless you're eating 100% organic vegetables and meats and products, the likelihood of you consuming some sort of chemical substance on your food, is very high. Even stuff labeled Organic grown has some sort of chemical process preformed on it.

      Yeah, yeah, my sister's an MIT alum, too. I'm quite familiar with the general sense of humor shared by denizens of the Infinite Corridor.

      I think the point here is not that "all chemicals are bad", but that lax regulation of the food industry in the U.S of A. allows companies to put unnecessary and potentially toxic chemicals in their products.

      Dihydrogen monoxide can be extremely deadly, by the way. If you ingest a mere 2-3 gallons of the stuff all at once, you will likely expire from electrolyte imbalance. It's not really that much at all. I live in the desert and consume this much over the course of an average hot summer day – just not all at once.

      And don't even get me started on the effects of INHALING DHMO – it'll just croak you right then 'n' there!

    Here's a list of the ingredients of McDonald's scrambled eggs: Pasteurized whole eggs with sodium acid pyrophosphate, citric acid and monosodium phosphate (added to preserve color), nisin (preservative). Prepared with Liquid Margarine: Liquid soybean oil, water, partially hydrogenated soybean oil, salt, hydrogenated cottonseed oil, soy lecithin, mono-and diglycerides, sodium benzoate and potassium sorbate (preservatives), artificial flavor, citric acid, vitamin A palmitate, beta carotene (color). Yummy!

    while living in Japan for a year, I ate McDonalds 4-5 times a week. The burgers and nuggets tasted significantly different, yet edible and appealing. I was able to lose almost 40 pounds that year. (McDonalds diet plus walking 3-6 miles a day and riding bike over 12 thousand miles also helped)

    Another Chemist says: (since i took polymer in the 12th grade, i must be stupid)

    Well neither of the chemicals mentioned are really concerning . TBHQ is an almost ubiquitous preservative. Dimethylpentylsiloxane (a specific conformer of the poly form they mention here) is used in over-the counter anti-gas tablets.

    Here's another angle: if you knew the chemical names for natural products, would you still eat them. Instead of fiber, try cellulose. Instead of saturated fat, try tri-acyl glycerol. Far nastier chemicals occur in nature, and they are natural toxins. We are made of chemicals, people. They just happen to be in a naturally-selected (be careful about how you interpret this phrase) equilibrium. Also, our livers have the abilities to metabolize chemicals in families of shapes and structures. Anything from anti-biotics to caffeine, it can handle them all. The word is 'cytochrome'

    They talk about calorie content and fat content, when they should be talking about the CHICKEN content, which is actually pretty minimal in a chicken mcnugget.

    They should also look at SODIUM content, which is always higher in North American foods compared to the equivalent European versions.

    Another case of sensationalist reporting, and another chance for 80% of you to show yourselves as the sheeple you are.
    Dimethylpolysiloxane is the main ingredient of Gas-X. Other than the ability to reduce surface tension, and therefore make bubbles hard to form, it's inert.

      When you reduce the surface tension in the digestive system, you encourage unnatural absorption into the body. Chemicals that would normally pass thru us are instead metabolized .

    CNNJunkie12:
    It's either a rule or not. If it isn't to be taken literally, then it means nothing because you have to either literally eat something or literally not eat it.

    Most people can't pronounce "quesadilla" either. It's just a stupid fear-mongering "rule" which people can spew out and not back up. It is an expression of ignorance and inability to comprehend health issues.

    "One gram" warning is also dumb. One gram of Iron could also kill you, but a few milligrams per meal are necessary for good health.

    That is exactly why I gave up eating meat. You never know what you are gonna get. One time, I saw a Tyson chicken truck going through Texas in 110 degree weather-on the way to the slaughter house I suppose, and the smell was atrocious! 1/3 of the chickens appeared to already be deceased from the horrible conditions they were in. And some other's were bloody. I gave up eating meat right then and there. Especially after I read the side of the truck "For a healthy lifestyle, eat chicken." Screw that. Never ever ever again.
