February 2011 Newsletter
A frosty welcome to February for everyone! I watched the temps drop from -5 degrees at 5:30 am to -11 at 6:30am this morning. At least the sun is out and warmer weather is on the horizon!
Though it is a sunny day today, how much vitamin D do you suppose you are going to get if you venture outdoors? Not much. The angle of the sun and the lack of bare skin being exposed to the sun both prevent your body from making any vitamin D. I want to make sure you fully understand that there is NO vitamin D is sunlight. It has been called the Sunshine Vitamin but there is none of it found in sunlight.
It is the ultraviolet or tanning rays of the sun that change the cholesterol in your skin to vitamin D. For that to happen, you have to have your skin exposed to the sun for 10-20 minutes and no sunscreen can be on your skin. If you have naturally dark skin, it takes more sun exposure to make the same amount of vitamin D than it does for your pale pink neighbor. There is an informative video by Dr. Mercola on vitamin D at: http://articles.mercola.com/sites/articles/archive/2008/12/16/my-one-hour-vitamin-d-lecture-to-clear-up-all-your-confusion-on-this-vital-nutrient.aspx. The following information is from that link:
The Role of Vitamin D in Your Body
There are only 30,000 genes in your body and vitamin D has been shown to influence over 2,000 of them. That is one of the primary reasons it influences so many diseases, from cancer and autism to heart disease and rheumatoid arthritis.
A study by Dr. William Grant, Ph.D., internationally recognized research scientist and vitamin D expert, found that about 30 percent of cancer deaths-- which amounts to 2 million worldwide and 200,000 in the United States -- could be prevented each year with higher levels of vitamin D.
Vitamin D has a protective effect against cancer in several ways, including:
• Increasing the self-destruction of mutated cells (which, if allowed to replicate, could lead to cancer)
• Reducing the spread and reproduction of cancer cells
• Causing cells to become differentiated (cancer cells often lack differentiation)
• Reducing the growth of new blood vessels from pre-existing ones, which is a step in the transition of dormant tumors turning cancerous
Beyond cancer, the researchers pointed out that increasing levels of vitamin D3 could prevent diseases that claim nearly 1 million lives throughout the world each year! And other studies showed that you can decrease your risk of cancer by MORE THAN HALF simply by optimizing your vitamin D levels with sun exposure.
Vitamin D even fights colds and the flu, as it regulates the expression of genes that influence your immune system to attack and destroy bacteria and viruses. In fact, it is very rare for someone with optimized vitamin D levels to come down with the flu.
A bottle of Vit D3 with 5000 IU’s per capsule is $10 for 100. Most people need 1-2 of these a day during the winter. We also have a liquid form for those who can’t swallow pills. This is a cheap and easy way to help prevent cancer and even colds and flus.
I have recommended heart scans and cardiac MRI’s to people who have heart disease in their family or have high cholesterol and are worried about if they have plaque in their arteries.
