What Foods Are Good for Prostate Health and Which Ones to Avoid?

Tomatoes and tomato products lead the evidence base for specific prostate-protective foods through their lycopene content. The landmark Harvard Health Professionals Follow-up Study, following nearly 50,000 men over years, found that men consuming ten or more servings of tomato products weekly had significantly lower prostate cancer risk than those consuming fewer than one and a half servings. Cooked tomato products, including tomato sauce, tomato paste, and pizza sauce, provide lycopene in a more bioavailable form than raw tomatoes and represent practical, easily incorporated dietary sources.

Fatty fish consumed regularly provides omega-3 fatty acids with anti-inflammatory and potentially anti-proliferative effects relevant to prostate tissue. Observational studies have found associations between higher omega-3 intake and lower prostate cancer mortality risk, though the relationship between fish consumption and prostate cancer incidence is complex and context-dependent. The anti-inflammatory effects of omega-3s are relevant for BPH as well as cancer risk through their effects on the inflammatory environment in prostate tissue.

Cruciferous vegetables, pumpkin seeds, green tea, and pomegranate are additional foods with specific prostate health evidence. Pumpkin seeds are particularly relevant to BPH: they contain phytosterols including beta-sitosterol that have demonstrated inhibitory effects on the testosterone-to-dihydrotestosterone conversion that drives prostate cell growth, and clinical trials of pumpkin seed extract have shown improvements in BPH symptoms. Pomegranate juice contains ellagitannins that are metabolised by gut bacteria into urolithins with documented anti-proliferative effects on prostate cells.
