Monday 5/9/2011 Vitamin D Revisited

I've been talking a lot about vitamin D in the past few years.  New data suggests that inflammation is the culprit for the incredibly high incidence of deficiency of this nutrient.  Low levels of vitamin D have been correlated with high incidences of cancer, heart disease, autoimmune disorders, poorly functioning immune systems, and musculoskeletal disorders.

A new study from the American Journal of Clinical Nutrition found that 2 days after knee surgery serum levels of vitamin D dropped 40%, and that three months later levels were still 20-30% below presurgery levels.  These researchers showed that this directly correlated with acute inflammation after surgery.  Surprisingly, they also found that the study participants were deficient in vitamin D before the surgery--so deficient that they had secondary hyperparathyroidism!

More research is linking vitamin D to musculoskeletal disorders.  A recent study in Headache shows that headache increases with latitude and during seasons with shorter days.  They correlated this information with evidence that vitamin D has alleviated headaches in some studies to form a hypothesis that Vitamin D deficiency plays a key role in the development of headache in some people.

Another recent study from the Scandinavian Journal of Primary Care  found " a high prevalence of hypovitaminosis D in patients with non-specific musculoskeletal pain, headache, or fatigue."

Inflammation is likely at the root of many cases of vitamin D deficiency, and all chronic degenerative diseases.  If your D is low, get a test that compares Arachodonic Acid to EPA--this is a sensitive test for inflammation that compares omega-6's to 3's in your body.  If this ration is off it will deplete your vitamin D and erode your health.  For more info on omega-3's in health, search my website.

The moral of the story is, get your D tested!
