Elevated blood sugar and obesity strongly tied to swollen prostate

Benign prostatic hyperplasia is the name given to the age associated increase in the size of many men's prostates Researchers measured the size of the prostate with MRI in 422 men aged 27 to 84. It was found that men who were heavier on average than other men their age had an increased risk of suffering from BPH and obese men had a 350% increased risk of having an enlarged prostate (this was after they adjusted for normal weight gain with advancing age). Men with elevated blood sugar had a 300% increased risk of developing an enlarged prostate. Diabetics were more than twice as likely to have prostate enlargement versus diabetes free men. The research was performed at the University of California San Diego and is published in the July 2006 issue of the Journal of Clinical Endocrinology and Metabolism.

Studies show it is not the caffeine which helps decrease the risk of developing diabetes but probably the polyphenols.
