Studies presented at the American Urological Society (AUA) virtual meeting have suggested that plant-based diets are tied to a decreased risk of erectile dysfunction (ED), lower prostate-specific antigen (PSA) rates, and probably a reduced rate of total and fatal prostate cancer among younger men.

In a cohort of 1,399 men, investigators noted that those with a higher consumption of healthy plant-based diet (high hPDI scores) had reduced odds of having raised PSA (OR 0.47, 95% CI 0.24-0.95). In another study that evaluated 2,549 men from the NHANES database - 57.4% of them having some degree of ED - increasing the intake of plant-based foods was tied to a decreased risk of ED. 

Another prospective study included 27,243 men, followed up to 28 years, in the Health Follow-up study, and noted that among men aged ≤65 years at diagnosis, higher intake of plant-based food was linked with a lower risk of advanced prostate cancer (HR 0.68, 95% CI 0.42-1.10). Additionally, among younger men, higher intake of a healthy plant-based diet was associated with lower risks of total prostate cancer (HR 0.81 95% CI 0.70-0.95), as well as fatal disease (HR 0.53, 95% CI 0.32-0.90)… (Medpage Today)
