Men who often consume deep fried foods such as donuts, French fries and fried chicken, are more at risk of prostate cancer, a new study found.

The effect appears to be slightly stronger with regard to more aggressive forms of the disease, found investigators at Fred Hutchinson Cancer Research Center in US.

They found that this effect has more of a connection with aggressive types of cancer. The findings of the study were recently featured in the online edition of The Prostate.

Men who said they ate French fries, fried chicken, fried fish and/or dounuts at least once a week were 30 percent to 37 percent more likely to develop prostate cancer than those who ate such foods less than once a month.

"The link between prostate cancer and select deep-fried foods appeared to be limited to the highest level of consumption - defined in our study as more than once a week - which suggests that regular consumption of deep-fried foods confers particular risk for developing prostate cancer," researcher Janet L Stanford said.

Researchers examined data from about 1,500 men diagnosed with prostate cancer and about 1,500 men who did not have the disease. The men, who ranged in age from 35 to 74, provided details about their eating habits.

Deep frying may trigger formation of carcinogens in food. They include acrylamide, found in carbohydrate-rich foods such as French fries, chemicals formed when meat is cooked at high temperatures, aldehyde, an organic compound found in perfume, and acrolein, a chemical found in herbicides.
