Vitamin D for Good Health
Overview: Vitamins, vitamins, and vitamins! So much
has been written about vitamins it is difficult to determine if all
those dieticians have any idea what they are talking about. Well, some
do.
Recent studies suggest that the blood levels of vitamin D in our
bodies are much lower than they should be. There are a couple of reasons
for this low blood level. First, our bodies are not making enough
vitamin D from the sun’s rays because most of us spend very little time
outside in the sun. Most of us spend time out of the sun like in cars or
in the house. We are more concerned about skin cancer than a balance of
the essential vitamins and minerals necessary to maintain good health.
And when we go outside we cover ourselves with sunscreen, which cuts
down on vitamin D production.
When we are outside, the sun’s ultraviolet B
rays penetrate into our skin’s outer layer and produce a vitamin D
precursor. The liver and kidneys then process this precursor and
coverts it into the usable active form in your body that is known as
vitamin D3. At the same time that we’re staying out of the sun and
not producing vitamin D, we’re also not getting very much from our
diet. Vitamin D is fairly difficult to get in your diet because food
sources are pretty limited. Milk, fatty fish and egg yolks are three
of the main sources. But when we consider milk and eggs we think of
all the warnings about their consumption. It’s enough to give you a
head ache if you are really trying to figure all this stuff out.
So in short, we are not getting enough Vitamin D
from the sun or from our diet. In the meantime researchers are finding
more and more of the benefits from vitamin D. Vitamin D is as important
along with calcium for bone health and protecting your body from brittle
bones.
Benefits of vitamin D:
-
Helps maintain
strength and balance.
-
Helps the
immune system function correctly. Vitamin D is in almost every cell
in the body.
-
Helps treat
psoriasis.
-
May help stop
the uncontrolled growth of cancer cells including breast, prostate,
and colorectal cancers.
-
May play a role
in autoimmune disease. Research has found that people with higher
levels of vitamin D in the body are less likely to develop multiple
sclerosis (MS). Diabetes, also considered an autoimmune disease
since the cells of the pancreas are affected
The current recommendation for vitamin D is
between 200 and 600 international units (IU) per day depending on
your age. However, many dietitians think these recommendations are
too low and are pushing for them to be increased up towards 1000
IU’s a day. Dietary guidelines already suggested that people with
darker skin, elderly or people that do not get sufficient sunlight
need 1000 IU’s daily. The
less you are in the sun, the more vitamin D you need from food. Many
vitamins occur naturally in a variety of foods but not vitamin D. In
vitamin supplements there are two forms of vitamin D, vitamin D2 and
D3. You want the vitamin D3 form which is the more potent form.
