Sunshine and Vitamin D
Sunshine and Vitamin D
We have all been warned about the dangers especially of cancer from over exposure to direct sunlight. Now, however, doctors are showing concern that we are all shying away from sunshine too much, causing a definite lack of the vital vitamin D. Recent figures indicate that more than 60 per cent of the population have sub-optimal levels of the vitamin, with problems being worse in Scotland, the North of England and among ethnic minorities.
Vitamin D is essential for our well being and is produced naturally when our skin is exposed to sunlight. The vitamin is then carried in our bloodstream to the liver, where it is converted into the prohomone calcidiol. From there, it is converted into various forms which are important in a number of vital functions.
Vitamin D plays a key role in strengthening bones and helping prevent fractures in the elderly, and there is emerging evidence of its role in helping to prevent a range of other conditions including asthma, diabetes and mulitiple sclerosis. It helps to defend the body against microbial invaders and has a role in many other activities within the body.
Vitamin D can be found in a small number of foods, including oily fish, liver and egg yolks, and the Food Standards Agency says the most people should be able to get all the vitamin D they need from their diet and by getting a little sun.
At the end of the day, there is still some speculation about how much sunshine you need to ensure adequate Vitamin D levels; but the warnings are clear. Make sure you are well protected from too much sun and don’t risk sunburn, but nevertheless also do try to get adequate and regular exposure to sunlight to ensure you have enough Vitamin D.
