With flooding happening around the country, many of us may be feeling a bit low on the sunshine. An estimated 20% of people in the UK have vitamin D deficiency and for some such as the elderly are more likely to be affected.

Although further research is still needed this makes an interesting read – http://ajcn.nutrition.org/content/95/6/1357.long
