Abstract: Prostatic diseases affect men over the age of 45 and increase in frequency with age so that by the eighth decade more than 90% of men have Benign Prostatic Hyperplasia, (BPH), of which some progress to Carcinoma of Prostate (CaP). CaP, the most common malignancy in men, is also the second most common cause of death in men. Over the last three decades the mortality rate for CaP has steadily increased. There, however, are scant clues to the aetiology/pathogenesis of CaP. As treatment failures of advanced carcinoma continue to frustrate clinicians, emphasis has recently been focused on possible preventive strategies. Several studies support the view that higher levels of 1,25-(OH)2 D, the active metabolite of vitamin D, reduce the risk of BPH and CaP. Men with high serum levels of 1,25-(OH)2D have a reduced risk of poorly differentiated and clinically advanced CaP. Hypercalcemic activity of 1, 25-(OH)2D or its analogues, however, thwart their use for therapy in humans. Incidentally, a low dietary intake of phosphorus has been reported to increase serum levels of 1, 25-(OH)2 D. In addition, dietary fructose reduces plasma phosphate levels by 30 to 50% for more than 3 hr. Fruit intake has, indeed, been shown to be associated with reduced risk of CaP, particularly the advanced type. These observations, taken together, Support that dietary determinants of hypophosphatemia, leading to increased plasma levels of 1, 25 -(OH)2D, could reduce the risk of ageing men to develop prostatic diseases, both BPH and/or carcinoma of Prostate.
