Molecular Healing: Vitamin D, Cancer, and Fighting the Winter Blues
Posted Aug 24 2008 9:51pm
It has been a long and nasty winter here in the upper midwest. Today as I sit writing this entry I look out the window and see the freezing rain turning to snow while the gray skies shed little light. I feel like hibernating and find it difficult to get up the ambition to go outside and fight the elements. I did manage to do so and skated across the frozen driveway covered with freezing rain to drive to my favorite writing spot--a local coffee shop.
We northerners obviously don't get as much sun as our southern neighbors. Yes, we have less incidence of skin cancer but we also can end up with less of an important vitamin that is synthesized right in our skin. This vitamin is vitamin D.
Why is vitamin D so important? Well, recently Dr. Louise Parker, an international expert on cancer has some good things to say about vitamin D. According to Dr. Parker, vitamin D deficiencies have been turning up in a number of cancers such as lung and colon cancer. Even the Canadian Cancer Society is now recommending 1000 mg of vitamin D during the long Canadian winter months.
As a nutritional consultant I have recommended vitamin D for women to help counter the effect of osteoporosis, especially during menopause. There is an important link between estrogen and calcium absorption. Low estrogen inhibits the absorption of calcium and vitamin D facilitates it. Now research that has followed women taking vitamin D with osteoporosis has also shown a decrease in cancers. This may indicate and important link between the two.
Vitamin D has also been shown to inhibit MS and ward off the winter blues.
Vitamin D is a fat soluble vitamin but has little risk of causing harm. Dr. Parker recommends a dose of 1000 mg/day during the winter months.
Now I will have more good things to say about vitamin D.
