Although it's difficult to know for certain whether red wine directly impacts the PSA ( prostate-specific antigen) count, evidence indicates that a person's overall diet and health can play a role in prostate cancer risk, which could translate into PSA levels. PSA is a protein that's made in the prostate - a small gland about the size and shape of a walnut, although it usually enlarges with age. The prostate sits below a man's bladder and produces substances that help form semen. Normally, small amounts of PSA circulate in the blood. But cancerous prostate tissue usually releases more PSA than healthy tissue. The lower the PSA level, the lower the chance of having prostate cancer. The higher the PSA level, the higher the chance of prostate cancer.
