Vitamin D and Health a Paper by Dr Cannell (MD)

In this paper Dr Cannell discusses the following:

1. Why the flu predictably occurs in the months following the winter solstice, when vitamin D levels are at their lowest,

2. Why it disappears in the months following the summer solstice,

3. Why influenza is more common in the tropics during the rainy season,

4. Why the cold and rainy weather associated with El Nino Southern Oscillation (ENSO), which drives people indoors and lowers vitamin D blood levels, is associated with influenza,

5. Why the incidence of influenza is inversely correlated with outdoor temperatures,

6. Why children exposed to sunlight are less likely to get colds,

7. Why cod liver oil (which contains vitamin D) reduces the incidence of viral respiratory infections,

8. Why Russian scientists found that vitamin D-producing UVB lamps reduced colds and flu in schoolchildren and factory workers,

9. Why Russian scientists found that volunteers, deliberately infected with a weakened flu virus - first in the summer and then again in the winter - show significantly different clinical courses in the different seasons,

10. Why the elderly who live in countries with high vitamin D consumption, like Norway, are less likely to die in the winter,

11. Why children with vitamin D deficiency and rickets suffer from frequent respiratory infections,

12. Why an observant physician (Rehman), who gave high doses of vitamin D to children who were constantly sick from colds and the flu, found the treated children were suddenly free from infection,

13. Why the elderly are so much more likely to die from heart attacks in the winter rather than in the summer,

14. Why African Americans, with their low vitamin D blood levels, are more likely to die from influenza and pneumonia than Whites are.

I have been following the career of Dr Cannell for several years now and have sought his advice now and then about issues surrounding the use of vitamin D supplements.

To date I have not had a single person, including myself, produce a blood test result that is optimum for vitamin D levels.  Mine was 57nmols ("Healthy" Range 50-160nmol: Optimum 120-160nmol).

Here is the link for your vitamin D supplement to take on days that you get no sunlight on your naked body.

Hi Gary:

I was at a nutrition conference several years ago where a Boston physician told us his medical center was seeing 60 to 80 kids a year show up with rickets--the bone disease. Not enough Vit. D. Amazing in this day and age. Kids need to get outside, for God's sake!

Thanks for the info.
