Is vitamin D really a cure-all, and how should we get our fix?
I&#x27;m not going to wait for a study to show evidence. The evidence is only as good as the study, and this is very hard thing to setup a study for, given the many years they&#x27;d need to study subjects and as someone else pointed out on here, its systemic nature makes it hard to pinpoint.<p>The explanatory arguments are more than sufficient: skin colour corresponds to the availability of sunlight - with the exception of dark-skinned Inuits who maintain a fish based diet - which indicates the importance of vitamin D to survival.<p>Only in the modern era do we now spend more time inside than outside, which could be an explanation for increasing incidence of diseases.<p>As for this ridiculous quote:<p>&gt; And as Adrian Martineau, clinical professor of respiratory infection and immunity at Queen Mary University of London, points out, even in the summer, “sunshine isn’t going to be the answer, especially because there is an associated risk of skin cancer.”<p>No, sunshine is the answer. The risk of skin cancer is elevated if you get sunburnt, if you expose your pale skin suddenly to the sun in the height of summer. Nobody is suggesting you do that. Build up a tan gradually throughout the year, follow common sense.
