Vitamin D: Walk On The Sunny Side Of The Street
Author: Linda Polansky

Vitamin D is commonly discussed together with calcium as a
nutrient that can help your bones and teeth stay strong and for
older people or those with osteoporosis, less likely to
fracture.

Vitamin D and Women Breast Cancer

A recent study even shows that vitamin D may be
helpful in preventing breast cancer, though research in this
area is new and not widely proven yet.

Particularly as people live longer and are more likely to
experience weakened bones and the problems they can cause, it
is important to make sure that you get enough vitamin D.
However, you do need to be careful with vitamin D supplements
and look at how much you are getting in your diet as well.
Vitamin D is fat soluble and as such, is stored in the body.


Vitamin D Toxicity

That means if you get too much, it can be toxic. Toxic levels
of vitamin D can cause vomiting, constipation, and weakness and
over time can have more serious health effects on the heart and
kidneys.

Vitamin D is also unique in that our skin makes a form of it,
vitamin D3, when exposed to the ultraviolet B (UVB) in
sunlight. Excessive sun exposure is not necessary for this to
take place, but people who are rarely exposed to unobstructed
sunlight need to make sure that get more vitamin D in their
diets. Aside from fish, there are not very many food sources
that are naturally high in vitamin D. However, vitamin D is
added to most milk available commercially, and box cereals are
often fortified with it as well.

Vitamin D Deficiency

The addition of vitamin D to the commercial milk supply has been credited with the near elimination of rickets, a vitamin D deficiency in children,
though rickets is becoming a problem again in some parts of the
US.

Vitamin D by itself does not strengthen bone. Once you take in
a vitamin D supplement, consume it in food, or your skin makes
it, your liver and kidneys change it into a hormone that helps
your body absorb more calcium, and it is the calcium that helps
your bones. Vitamin D can only help your body use calcium if you
are putting calcium in it, so you need to make sure you are
getting enough calcium as well. Many supplements will contain
both, and foods that are fortified with vitamin D usually have
calcium in them also. Some studies show that vitamin D also is
good for your immune system.
