Abstract
We performed systematic review and meta-analysis of published studies that investigated the potential association between fried food consumption and prostate cancer risk. Four case–control studies were finally selected for this systematic literature review, totaling 2579 cancer patients and 2277 matched controls. In two of these studies, the larger intake of fried food was associated with a 1.3- to 2.3-fold increased risk of prostate cancer, no significant association was found in another, whereas an inverse relationship was observed in the remaining. The meta-analysis of published data showed that larger intake of fried food was associated with a 35% (95% CI 17–57%) increased risk of prostate cancer. The results of this systematic literature review support the notion that larger intake of fried foods may have a role in increasing the risk of prostate cancer.
