Enter your answer This question doesn't meet the point. Selenium does not cause diabetes, in reality a few publications found (like the one cited above by Stranges et al. 2010) an association between high blood levels or intakes with a higher risk of diabetes. I hope everyone remembers the Nature publication on the decrease on birth rates and the decrease in stork populations?! In other studies (e.g. SELECT) a statistically non-signficant risk for type 2 diabetes with high selenium intake was postulated. It even led to the preterm break of this trial. In later follow-up publications this result could not be substantiated, but this fact has never been discussed in the media or the scientific literature. A third point to consider: selenium is not selenium. Organic selenium compounds differ enormously from inorganic sodium selenite. Therefore inorganic selenium compounds should not be used, and sodium selenite is the only substance worldwide to be registered in pharmacopoeias as an active pharmaceutical ingredient (API). Nevertheless, still a lot of People (e.g. in the Diabetes papers) use organic selenium compounds.

We are currently critically reviewing the scientific evidence on the selenium-diabetes-connection to clear these points in detail. I will then provide extensive comments when the paper is ready.

Dear Prof.Guenther Stoll,

thank you so much for the answer. Looking forward to hear from you again. 

Thank you
