Dr Cannell reviews a recent paper by Dr Wimilawansa.

Sunil J. Wimalawansa. Vitamin D in the New Millennium. Current Osteoporosis Reports, Volume 10, Number 1, 2012.

In the paper, Wimilawansa discusses the magnitude of the vitamin D deficiency pandemic and the latest research developments in vitamin D and its wide arrange of effects on disease prevention. Dr Cannell covers it all here:

    Video is a very inefficient way to present what is essentially textual information. Two or three paragraphs of text would have sufficed and would not have taken fifteen minutes. At least provide the name of the guy (I at least was unable to convert the pronounced version to a spelled version) and the name of the book.

      John,
      Thanks for the feedback. In the surveying we have done, we have found that video blogs are an effective way to communicate to the public and that people generally enjoy them more than written content — this is true whether or not the video delivers engaging and animated “b-roll” or just textual information. There are some people that use YouTube/video format to deliver strictly podcasts/audio, too. Mercola comes to mind here. Obviously vlogs and podcasts are not for everyone, and on the hand, written blogs are not for everyone either. Our aim is to deliver both.

      James has been kind enough to post the link to the cited Wimalawansa publication below. We’ll definitely aim to provide it sooner next time. Cheers.

    Dr Cannell, what is your take on Vitamin D and effect of diet on pH? There are many peer studies that show acidosis causes connexins to close so the cells can not communicate and share nutrients. Also, if there is acidosis, the body will grab calcium from bones and/or not allow it to be absorbed into bones in order to keep blood near 7.4 pH, even if Vitamin D is adequate. Please comment. — Dan

    And if calcium is not absorbed it floats in blood and attaches to cholesterol which is very dangerous for stroke and general inflammation.

    Regarding fortifying more foods with Vitamin D3, might that then make Vit D3 supplementation dangerous? There needs to be inexpensive 25(OH)D at home in order to know the level twice per year.

    • Brant Cebulla

      Dan,
      I think that’s a fair argument. My feeling is that if we began fortifying food, it would be at small amounts, with the aim to get the population above 20 ng/ml, not 50 ng/ml.

      I think cheaper testing will be on its way in the future as well.

    I could not find the name of the author referred to in the video blog
    I do not know the spelling.

    400 ug per serving of bread? Did you perhaps mean 400 IU

    Six vitamin d experts’ “optimal” 25(OH)D levels:
    Disease Incidence Prevention by Serum 25(OH)D Level
    See Robert Heaney’s “pet peeve” about terminology beginning @ 20:52 of the link in his name…
    @ :36:54 Conclusions
    — serum 25(OH)D levels below 80 nmol/L [32 ng/ml] are not adequate for any body system. (Calcium absorptive regulation is suboptimal below 80 nMol/L [32 ng/ml] )

    — levels of as high as 120 nmol/L ( 48 ng/ml ) may be closer to optimal

    @ :22:50 “…better than 85%…would have been below 80 nMol/L [32 ng/mL]…So, as a kind of a generalization — in Boston, at least — patients on a general medical ward are effectively all vitamin D deficient — the vast majority of them.”

    The body’s Ph is tightly controlled (homeostasis). Ideally everyone will eat lots of veggies, but it’s generally difficult to affect the ph significantly.

    For me, the Springer link:

    http://www.springerlink.com/content/2q8672527223n5q1/

    drew:

    Access to this content is restricted to subscribers.

    However, the abstract at least can be found here:

    Whoops! Cancel that. A retry of the Springer link brought the article up right away.

    Curious. I still had the failed tab up; it’s URL reads:

    https://springerlink3.metapress.com/content/2q8672527223n5q1/resource-secured/?target=fulltext.html&sid=kycm3hvfwfxer5qnsrb13hhi&sh=www.springerlink.com

    I’m not aware of having done anything different in my two attempts with the Springer link.
