　　Crispy fried foods are popular all over the world, but new animal experiments conducted by American researchers show that fried foods can exacerbate intestinal diseases, such as inflammatory bowel disease and colon cancer. They called on patients with bowel disease and high-risk groups to eat less fried foods. Researchers from the University of Massachusetts Amherst have published related papers in the new issue of the American Journal of Cancer Prevention Research. They added a mixture of frying oil and fresh vegetable oil to a group of rat food, while only fresh vegetable oil was added to the control rat food.

　　The results showed that mice fed the mixed oil showed signs of increased inflammation in the colon, and the size of the intestinal tumor was twice that of the control group, which increased the leakage of the intestine and the entry of bacteria into the blood circulation. it is. Researchers believe that the oxidation of polyunsaturated fatty acids in oil plays an important role in human inflammation after heating. In the frying process of edible oil, repeated use of oil at high temperature will cause oxidation, polymerization, decomposition and hydrolysis reactions, and the generated compounds (such as carbonyl, carboxyl, ketone and aldehyde) are more polar than ordinary vegetable oil molecules. Will be higher. , It is called a polar compound. To test this hypothesis, the researchers separated polar compounds from frying oil and fed them to mice. The results showed that the progression of enteropathy in these mice was similar to that of fried-fed mice, indicating that polar compounds play an important role in the inflammatory response.

　　However, these findings do not mean that eating fried foods or frying oil can cause cancer, but that eating fried foods can cause enteritis, intestinal cancer and other intestinal diseases. Patients with intestinal diseases or high-risk patients with intestinal diseases emphasize that patients with intestinal problems should eat less fried foods.
