In Place of Sunshine?


The debate continues about Vitamin D (the so-called 'sunshine vitamin as it is manufactured under the skin after exposure to UV light) and health  (https://www.theguardian.com/science/2018/mar/09/is-vitamin-d-really-a-cure-all-and-how-should-we-get-our-fix). In less sunny locations (e.g. winter in the UK), producing enough of your own vitamin is problematic, leaving the diet (mainly oily fish) and supplements as the only easy alternative means of getting sufficient. Having a darker skin; wearing heavy clothing or covering oneself with high factor sun-cream (to avoid skin cancer) all reduce the efficacy of sunshine and being vegan limits increasing the vitamin via the dietary route. Given that vitamin D has now also been claimed to reduce the risk of cancers (in addition to the longer-established health benefits), some people are now suggesting that supplements should be more commonly employed (especially by groups of people with likely deficiencies).
