The Facts:
* Selenium is a trace element that is essential for good health.
* Researchers in Belgium studied the link between levels of selenium in the blood and the risk of bladder cancer in over 500 patients.
* The results showed that low levels of selenium were associated with an increased risk of developing bladder cancer.
Shaun’s comment: This was an excellent study, which compared a group of people with bladder cancer (“cases”) with a group of similarly aged people living in the same area without the disease (“controls”). As selenium is thought to prevent cancers, the researchers looked at whether those with more selenium in their blood would have less chance of getting cancer. And that is precisely what they found. This would appear to be yet another potential benefit from having a good intake or selenium, either in food or as a supplement.
