Polyphenols are a diverse group of naturally occurring compounds found abundantly in plant-based foods, including fruits, vegetables, tea, and certain herbs. There is growing scientific interest in the role of polyphenols in supporting prostate health, particularly in relation to benign prostatic hyperplasia (BPH) and prostate cancer risk. Several epidemiological and preclinical studies suggest that diets rich in polyphenols, such as those found in green tea (catechins), soy (isoflavones), and pomegranate (ellagitannins), may be associated with a lower risk of prostate-related disorders. The proposed mechanisms include antioxidant activity, anti-inflammatory effects, and modulation of signaling pathways involved in cell proliferation and apoptosis within prostate tissue.

Clinical evidence is moderate but promising. For example, green tea catechins have been evaluated in several randomized controlled trials, with some showing reduced progression of prostate intraepithelial neoplasia and improvements in lower urinary tract symptoms. Soy isoflavones have also been studied, with mixed but generally positive findings regarding prostate-specific antigen (PSA) levels and symptom relief. However, most studies are limited by small sample sizes and short durations, and results are not always consistent.

Overall, while polyphenols are not a primary treatment for prostate conditions, there is moderate scientific evidence to support their adjunctive role in maintaining prostate health, particularly as part of a balanced diet. Further large-scale, long-term clinical trials are needed for conclusive recommendations.
