Previous studies have shown high doses of Acrylamide to lead to cancer in laboratory animals, but researchers say humans don't consume doses high enough to increase their cancer risk. The study tracked the eating habits of 1,500 people, two-thirds of whom had cancer of the colon, bladder, rectum, or kidney.
It found no difference in cancer risk in people whose diets were heavy on high carbohydrate, high Acrylamide foods like french fries and crackers. In fact, researchers say people who ate the highest amounts of Acrylamide had a slightly lower rate of bowel cancer. But experts say that benefit may come from the high fiber content of the foods.
Scientists say the high heat needed to make fries, chips, and some kinds of cereals and breads triggers a reaction between natural amino acids and certain sugars, creating Acrylamide.
The study was conducted by researchers at Harvard School of Public Health and the Karolinska Institute of Sweden. It is published in the British Journal of Cancer.
