Swedish researchers have found that certain foods heavy in carbohydrates contain a compound called acrylamide which US researchers have confirmed in the past as a carcinogen.
Lab animals have developed tumors when exposed to acrylamide. Acrylamide seems to pop up in food when bread is baked or fries are fried in oil. Researchers found it when they heated rice, cereals and potatoes.
The scary thing is that found unsafe levels of acrylamide in fries fast food chains sell and potato chips. The US Food and Drug Administration is skeptical and believes the Swedish study need more scrutiny before they make any changes.
