Objective: As men age total dietary mineral bioavailability falls which may increase the risk of prostate cancer. The aims of this study were to investigate the changes in main mineral contents in prostate gland that occurred with aging. Design: Population based study on changes in mineral contents in prostate gland with ageing. Participants and setting: 65 free-living healthy men aged 21-87 years who had died suddenly. Prostates were removed at necropsy and the samples of morphologic normal prostate tissue were investigated. Measurements: Contents of ten main minerals (B, Ca, Co, Cr, Cu, Fe, Mg, Mn, Se, and Zn) were determined by four instrumental analytical methods. Results: No any age-related deficiencies in minerals such as B, Ca, Co, Cr, Cu, Fe, Mg, Mn, Se, and Zn in the prostate tissue were found. Moreover, the mean mass fractions of Co, Fe, and Zn in prostate tissue for the age group adult men aged 41 years and older were statistically significant higher than for those younger than 40 years. Conclusions: Ageing is not associated with reduced mineral contents in prostate gland resulting in inadequate intakes in nutrients. Nutrition policy for men aged 41 years and older should include advice to decrease intakes of red meat for the purpose to reduce Fe and Zn intake.
