If we had more sun, there would be fewer coughs and colds – fact. Up to 10 million Brits are simply not getting enough sunlight to make the right levels of Vitamin D. That’s about 1 in 5 adults and 1 in 6 children.
Certain people are more at risk, especially between October and April when the sun is practically non-existent. But a tanning bed is not the answer.
We talk to health expert and NHS weight loss consultant, Dr Sally Norton to give us a low down on all things Vitamin D…
What has the sun got to do with it?
Well, quite a lot! We don’t get much Vitamin D from foods – we make it in our skin when it is exposed to sunlight. The winter sun is insufficient and not of the right wavelength for us to make much Vitamin D.
Sunlight is so important that statistics show 8% of adults have Vitamin D deficiency in the summer compared to 39% in winter. When we don’t get enough sunlight, our Vitamin D levels decline – it’s that simple.
Why do we need Vitamin D?
We all know that Vitamin D is essential for healthy bones; it helps our bones to mineralise, keeping them hard and strong. And research has suggested that Vitamin D aids our immune system. This is not only what helps use to ward off coughs and colds but has also been linked to a reduced risk of developing Multiple Sclerosis (MS). Interestingly, deficiency also appears to be linked with obesity and depression.
Who is at risk of Vitamin D deficiency?
Any of us could become Vitamin D deficient without the right levels of sunlight, or a supplement. However, for some groups of people it is especially important they get the right levels of Vitamin D – either because they are more at risk of deficiency or because their need is greater. These groups are:
• Children under 5
• Pregnant and breastfeeding women
• People over 65
• Those with low, or no exposure to the sun
• People with darker skin
What can you do?
Oily fish, such as salmon, sardines and mackerel, and eggs are sources of Vitamin D. They are also good sources of omega 3 and protein anyway, so are worth making part of your diet.
Also good is to get outdoors at every opportunity – fresh air and exercise have numerous other benefits too. If you think you could be at risk of Vitamin D deficiency, then you could speak to your doctor, who may be able to run a routine test to check on your Vitamin D levels. Alternatively, just take a supplement in the winter.
The recommended daily amount of Vitamin D is around 10 micrograms/day (400 IU) for an adult. For babies and young children, the recommended daily amount of Vitamin D is 7 – 8.5 micrograms. Don’t think that more is better – overdoing it could cause side effects.
So, in a nutshell, eat plenty of oily fish, get outside in the fresh air as often as possible, and certainly when the sun is out. Consider taking a supplement during the winter months at least, and perhaps all year round if you are in a higher-risk group.
