I posted an article on Vitamin D earlier in the wk for the community as I thought it to be useful for discussion/interest on the pathway for vitamin D. Almost 100% of the articles published in media medicine discuss Vitamin D isolates including the article "The Vitamin D Epidemic..." Not all articles on the blog do I agree 100% but rather post for general discussion... I don't have to agree with the points/discussion. Below article is posted for discussion related to the objection of Vitamin D isolates and related topics. The interview is with Chris Kresser. For those of you that do not know of Kressers work please visit his website www.chriskresser.com... well worth your time
Surprising New Vitamin D Research
By Chris Kresser May 22, 2013
So I want to talk about a couple different things today, and we’re going to start with vitamin D.
There’s a lot of new research coming out that is pretty surprising, I think, to many of us who’ve been following this issue for a while, perhaps more surprising to people who’ve been recommending really high levels of vitamin D.
For the last several years I’ve been warning against excessively high levels of vitamin D for some of the reasons we’re going to talk about today, but there’s a lot of controversy about this.
The science is definitely mixed and inconsistent, and the jury is certainly not out.
Vitamin D deficiency is now recognized as an epidemic in the United States. The major source of vitamin D for both children and adults is from sensible sun exposure. In the absence of sun exposure 1000 IU of cholecalciferol is required daily for both children and adults. Vitamin D deficiency causes poor mineralization of the collagen matrix in young children’s bones leading to growth retardation and bone deformities known as rickets. In adults, vitamin D deficiency induces secondary hyperparathyroidism, which causes a loss of matrix and minerals, thus increasing the risk of osteoporosis and fractures. In addition, the poor mineralization of newly laid down bone matrix in adult bone results in the painful bone disease of osteomalacia. Vitamin D deficiency causes muscle weakness, increasing the risk of falling and fractures. Vitamin D deficiency also has other serious consequences on overall health and well-being. There is mounting scientific evidence that implicates vitamin D deficiency with an increased risk of type I diabetes, multiple sclerosis, rheumatoid arthritis, hypertension, cardiovascular heart disease, and many common deadly cancers. Vigilance of one’s vitamin D status by the yearly measurement of 25-hydroxyvitamin D should be part of an annual physical examination.
Worth your time. 3 parts to a 20 min speech by author and columnist George Will. He describes in a direct and entertaining way the root issues troubling most Americans today... such as described issues with the Department USDA; 1 USDA bureaucrat per 19 farmers compared to when the USDA was formed, 1bureaucrat per 225,000 farms.
