Frying Oil Worsened Colon Cancer and IBD in Mice

Frying Oil Worsened Colon Cancer and IBD in Mice
Consuming frying oil may worsen colon inflammation and colon cancer, a study in mice suggests. The study, "Thermally processed oil exaggerates colonic inflammation and colitis-associated colon tumorigenesis in mice," was published in the journal Cancer Prevention Research. From french fries to falafel, lots of foods are fried in vegetable oil. Consuming this oil may have health risks, but most studies done have focused on its effect in people who don't have ongoing diseases in their guts. In this study, researchers set out to determine the effect of this oil consumption in mouse models of colon cancer and inflammatory bowel disease (IBD). The researchers used consumption-grade oil commonly used in America, in which falafel had been fried. They added that oil to the food of some mice, while other mice were given food supplemented with oil that had not been used for frying. "We tried to mimic the human being's diet," Jianan Zhang, a PhD student at UMass Amherst and co-author of the study, explained in a press release. The researchers compared inflammation, colon tumor growth, and leakage of gut bacteria in both models, finding that eating the frying oil worsened all those conditions. For example, in the cancer model, "The tumors doubled in size from the control group to the study group," said study co-author Guodong Zhang, who is a professor at UMass Amherst. Since frying oil worsened thes
