Is diet a risk factor for benign prostatic hyperplasia and carcinoma prostate?

Objective: to find an association between diet and benign prostatic hyperplasia (bph) and carcinoma prostate (cap). methodology: ninety three out of 250 subjects were selected representing the normals, bph and cap cases; food frequency questionnaire was duly filled. food intake was calculated by using food guide pyramid and was categorized as low, moderate and high. in addition to common diets, we studied consumption of reused oil/ghee in our study. results: no association of protein, milk and milk products, cereals, fats (saturated/ unsaturated/both fats, oil/ghee branded or unbranded), vegetables, fruits and smoked food/ barbecue was found with bph and cap cases. but there was a significant association between oil/ghee reuse and bph and cap. conclusion: this study did not find an association between the common diet components and bph and cap cases. however a significant association was observed in case of oil/ghee reuse. so it is concluded that commonly used diet components in our setup could not be incriminated as etiological/risk factors for bph and cap in our community except reused oil/ghee and hence forth its consumption must be stopped
