Scientists reporting in the September issue of Cancer Epidemiology, Biomarkers & Prevention say that adults with low blood levels of the mineral selenium are more likely to develop bladder cancer. The lower your levels of selenium, the higher your risk.
Selenium is a trace mineral found in soil. Dietary sources of selenium include plant foods and meats from animals that grazed on grain or plants grown in selenium-rich soil. The nutrient is also found in certain nuts. For example, brazil nuts often contain an abundance of selenium.
A meta-analysis by researchers in Spain indicates selenium may help decrease bladder cancer risk.
Study leader Dr. Nuria Malats of the Spanish National Cancer Research Center in Madrid says dietary sources of this essential micronutrient include plants grown in selenium-rich soils or animals that graze on the soils -- as well as selenium-enriched products.
