The epidemic of childhood allergy has been mirrored in an increasing global predisposition to Vitamin D deficiency. While, specifically childhood asthma has more closely been linked to low levels of Vitamin D in recent medical research.  This problem has become increasingly apparent with the advent of  routine Vitamin D blood testing. In the UK, the bone disease  Rickets, caused by a lack of Vitamin D in children, has started to reappear and this may in part be due to an aversion to sun exposure caused by skin cancer prevention campaigns, an obsession with sun blockers and a more sedentary indoor childhood lifestyle at the helm of the computer games console. These lifestyle changes are a deterent to outdoor sports, school field trips and just enjoying playing outside in the sunshine .  Vitamin D can be substituted by taking a weekly dose of calciferol, but somehow good old fashioned sunshine sounds more natural.
