BPH.

Benign prostatic hyperplasia (BPH) is a common, noncancerous enlargement of the prostate gland, common in American and European men over the age of 50. While the actual cause is not completely understood, experts believe it is closely linked to hormone levels. Try the following to help reduce the risk of BPH:

Eat a diet low in saturated and trans-fats, focusing instead on the healthier monounsaturated and omega-3 fats.

Eat more whole soy foods. Asian men have a lower risk of BPH and some researchers believe it is related to their intake of soy foods.

Avoid symptom triggers such as caffeine and alcohol, which increase the need to urinate and may irritate the bladder. Avoid constipation by increasing fiber in your diet. The pressure from constipation may make the symptoms of BPH worse.

Have regular check-ups. The National Institute on Aging recommends that men get regular medical checkups including a prostate exam.
