Vitamin D deficiency in Africa | Central Europe's low numbers

Posted by: The Conversation Global

Date: Tuesday, 30 June 2020


Exposure to sunshine for a few minutes a day is enough to provide us with sufficient vitamin D. Because people living in Africa are exposed to more sunshine than their northern cold climate counterparts, a common view has developed that they have less of a vitamin D deficiency problem. But this isn’t true. Reagan Mogire sets out what he found doing a review of research on the issue in Africa and why under-diagnosis is a serious problem.

Croatia, Slovakia and the Czech Republic have had much lower death rates than most Western European countries. Jan Culik and Mirna Solic ask: why has so little attention been paid to these apparent successes in the east?
