Maybe just a Fries are still fattening, but new research minimizes the risk of acrylamide to cancer.
Less than a year ago, Swedish scientists have caused widespread concern among health officials and the general public when they detected high concentrations of acrylamide - a potent carcinogen in laboratory animals - in bread, potato chips and french fries. But a new study finds no link between dietary acrylamide and cancer in humans.
Acrylamide forms when the starch-based foods are baked or fried at high temperatures. Because the substance causes cancer in rats and mice, acrylamide is known to be neurotoxic in humans and is considered potentially carcinogenic to humans too. So far, however, no direct evidence supported this hypothesis.
Lorelei Mucci of the Harvard School of Public Health in Boston and colleagues at the Karolinska Institute in Stockholm studied the diets of 987 cancer patients and 538 healthy people. Based on detailed questionnaires, the team estimated the contribution of each of acrylamide. In what appears to be good news for junk food lovers, they found no link between acrylamide consumption and cancers of the colon and rectum, kidney or bladder cancer - the most common cancers associated with food carcinogenic. While Mucci warns that it is too early to declare acrylamide sure. "We do not want to generalize from these initial data," she said, citing the need to investigate links to other forms of cancer. The team reports its findings in the January 13 of British Journal of Cancer .
"There are many things in animal studies that pan when we look at the man," said Harvard University epidemiologist Eric Rimm's, which was not associated with 'study. "For me, it does not come as a surprise." However, he cautions that the study is not definitive, in part because of the lack of comprehensive data on acrylamide levels in various foods. And epidemiologist Lars Hagmar of Lund University, Sweden, added that the study may have been too small to detect risks likely involved with acrylamide minute. "I find conclusive study," said Hagmar
