Regular consumption of deep-fried foods such as French fries, fried chicken and doughnuts is associated with an increased risk of prostate cancer, and the effect appears to be slightly stronger with regard to more aggressive forms of the disease, according to a study.
For the study, researchers at Fred Hutchinson Cancer Research Centre in Seattle analysed data from two prior population-based case-control studies involving at total of 1,549 men diagnosed with prostate cancer and 1,492 age-matched healthy controls.
The men were Caucasian and African-American Seattle-area residents and ranged in age from 35 to 74 years. Participants were asked to fill out a dietary questionnaire about their usual food intake, including specific deep-fried foods.
The researchers found that men who ate French fries, fried chicken, fried fish and/or doughnuts at least weekly had an increased risk of prostate cancer that ranged from 30 to 37 percent.
Weekly consumption of these foods was associated also with a slightly greater risk of more aggressive prostate cancer.
