Nutrition seems to modify the pathogenesis of benign prostatic hyperplasia (BPH) effect symptomology in men suffering from lower urinary tract symptoms (LUTS). Although there are numerous pharmaceuticals and procedures for these conditions, nutrition may improve outcomes as a primary approach or in tandem with BPH medications or procedures. The purpose of this review is to highlight the benefits of nutrition and dietary supplements in men with BPH and LUTS. Dietary factors have an impact on metabolic disorders that lead to diabetes and obesity - both of which inversely effect BPH and LUTS. Dietary patterns associated with increased risks include starches and red meats, whereas moderate alcohol intake and polyunsaturated fat and vegetable consumption decrease risks. Dietary supplements of zinc, saw palmetto, and beta-sitosterol in relieving BPH symptoms have had mixed results. Randomized clinical trials of nutritional practices and other lifestyle alterations such as exercise for the prevention or treatment of BPH and LUTS have yet to be performed. Nutritional practices may provide for the prevention and treatment of BPH and LUTS while positively affecting other systemic parameters. Whereas there are a few clinical randomized trials for the prevention and treatment of BPH and LUTS, nutritional modifications may have a healthy lifestyle alternative with minimal to no adverse effects.
