Is there anything a man can do to lower his PSA?

Simple Dietary Changes That May Help Lower PSA Levels

For men concerned about prostate health, keeping PSA (prostate-specific antigen) levels in check is often a priority. While PSA levels can be influenced by a variety of factors—including age and genetics—lifestyle and diet play a meaningful role. The good news? Small, intentional changes in what you eat may make a difference.

Green tea and soy are two dietary additions that have shown promise in clinical studies. Green tea, rich in antioxidants called catechins, has been linked to a reduced risk of prostate cancer, especially in men at higher risk. Regular consumption may help support overall prostate health and potentially lower PSA over time. Soy, found in foods like tofu, edamame, and soy milk, contains isoflavones that some research suggests may help reduce PSA levels. Men in Asian countries, who typically consume more soy, tend to have lower rates of prostate cancer—an observation that’s sparked ongoing interest in its protective effects.

On the flip side, it’s wise to avoid charred meat. Cooking meats at high temperatures—especially grilling, frying, or charring—can create harmful chemical compounds such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which have been associated with an increased cancer risk. These compounds may not only affect overall cancer risk but could also influence prostate health and PSA levels.

While diet alone isn’t a cure-all, combining these changes with regular check-ups and a healthy lifestyle can go a long way. It’s not about perfection, but consistency—small choices adding up to meaningful protection. As always, it’s best to discuss any major dietary changes with your doctor, especially if you have a history of prostate issues.
