VITAMIN D

The body needs Vitamin D to maintain and build strong bones.
The body produces its own vitamin D when the skin is exposed to the UV rays of the sun.
The sun is the main source of Vitamin D but that does not mean you have to suntan the whole day.

If you enjoy the sun sensible, it will be possible for the skin to make enough of
the Vitamin D the body needs without the risk of skin cancer.
To enjoy extra time in the sun does not mean that you will keep on producing Vitamin D.
The body just breaks down any excess.

It depends on quite a few things for the amount of time you need in the sun to make Vitamin D. ie. - Skin type, time of year, where you are in the world and time of day.

Winter sunlight has low levels of UVB so the skin cannot make the Vitamin D it needs.
That is why you should get enough sun in the summer so that normal levels are built up for the body to store enough Vitamin D to last through winter.

You can find Vitamin D in some food like egg, some fortified cereals,fish liver oils and fatty fish.

Studies show that the body getting enough Vitamin D can help reduce the risk of bowel cancer.
