Acrylamide: What Is It, and Which Foods Contain It?

For me, the most fascinating segment of Morgan Spurlock's documentary on McDonalds, called Super Size Me, involved the man who has become famous for eating almost nothing but Big Macs since 1972. Don Gorske is the Guinness world record holder for number of Big Macs eaten, having passed 19,800 Big Macs as of June, 2004.

Don has eaten anywhere between 2 and 9 Big Macs per day, almost every day since 1972, and yet, his height-weight ratio and blood tests indicate that he is in relatively good health.

What I find particularly interesting is that he reports almost never eating French fries. This is in line with my personal belief that French fries are the worst item on the menu at fast food restaurants. Sure, coca cola, processed cheese, and factory farmed meats aren't much better. But every ounce of those crunchy, salty, tasty fries are so harmful to health that I wouldn't be surprised if several years from now, the government and general public come to view French fries the way that we view cigarettes today.

What's so bad about fries?

They are loaded with trans fats, known to cause immune system depression, cardiovascular disease, diabetes, obesity, sterility, birth defects, decreased ability to produce breast milk, loss of vision, and weakening of your bones and muscles.

French fries are also high in acrylamide, a carcinogen that is found in starchy foods that have been fried or baked at high temperatures.

The World Health Organization first began to look at the dangers of acrylamide in 2002 after the publication of a study in Sweden that linked acrylamide consumption with cancer. Since then, independent studies in the United States, Germany, Norway, Switzerland, and England have confirmed the link between acrylamide consumption and risk of developing cancer.

A few months after the original report out of Sweden, The Center for Science in the Public Interest in Washington, DC did its own study on the acrylamide content of the most common starchy foods in the North American diet. Their results were as follows:

Put another way, the amount of acrylamide found in a large order of French fries at a fast food restaurant is at least 300 times higher than what the Environmental Protection Agency allows in a glass of drinking water.

“I estimate that acrylamide causes several thousand cancers per year in Americans,” said Clark University research professor Dale Hattis. Hattis, an expert in risk analysis, based his estimate on standard EPA projections of risks from animal studies and limited sampling of acrylamide levels in Swedish and American foods.¹

If you were watching the news wires last week, you may have read that on June 16, 2005, the California-based Environmental Law Foundation filed notices with the state of California's attorney general against:

• Lay's potato chip maker PepsiCo Inc.
• Pringles maker Procter & Gamble Co.
• Cape Cod potato chip parent Lance Inc.
• Kettle Chips maker Kettle Foods Inc.

California law requires that companies warn their customers if their products contain known carcinogens. And acrylamide is listed by the California Office of Environmental Health Hazard Assessment as a chemical known to cause cancer.

The Environmental Law Foundation says that their most recent tests indicate that these potato chip brands "far exceeded the levels requiring warning labels under California law." Specifically, they noted that "Cape Cod Robust Russet potato chips exceeded the required warning level by 910 times, while Kettle Chips Lightly Salted chips exceeded the level by 505 times."

Regardless of how this most recent legal battle goes, we are already well aware of the strong link between acrylamide consumption and risk of developing cancer. Please remember that raw or boiled potatoes test negative or very low for acrylamide. Acrylamide is formed in substantial quantities when starchy foods are fried or baked at high temperatures.

This means that French fries and potato chips are two of the deadliest foods that you can eat. So the next time that circumstances lead you to McDonalds, do yourself a favour and be like Don Gorske. Have a Big Mac and skip the fries. Better yet, have a salad from their lighter choices menu.
