Beware of this popular mineral contained in some supplements, it can increase the risk of prostate cancer if taken in excess

Don't store avocado like this: it's dangerous

It is widely believed that supplements are harmless but in reality they should be taken with due caution considering the risks, which are not uncommon. This is confirmed by a study published in the Journal of the National Cancer Institute, which highlighted the danger of taking some supplements containing selenium, but also vitamin E.





The study was conducted on a sample of over 35.000 men to evaluate whether the supplements in question, taken at high doses, could protect against the onset of prostate cancer.

During the research, the scholars realized that they even increased the risk. The results were based on data from the SELECT (Selenium and Vitamin E Cancer Prevention Trial) trial conducted from 2001 to 2008. 

Specifically, a 91% prostate cancer risk in men with high baseline selenium levels, who took high-dose supplements. And the risk was increased by 63% in men with low baseline selenium levels who took vitamin E supplements instead. 

The study's lead author, Dr. Alan Kristal of the Fred Hutchinson Cancer Research Center in Seattle, said - neither selenium nor vitamin E supplementation confers known benefits, only risks. While there appears to be no risk from taking a standard multivitamin, the effects of high doses of single supplements are unpredictable, complex and often harmful. 

Ultimately, do not overdo the supplements and above all do not take them too lightly, carefully evaluating whether or not it is appropriate to take them.
