Vitamin D insufficiency in southern Arizona
Abstract from American Journal of Clinical Nutrition, Vol. 87, No. 3, 608-613, March 2008, by Elizabeth T Jacobs, et al

While Vitamin D deficiencies are widespread throughout the U.S., there are few studies specifically pertaining to vitamin D deficiency in "sunbelt" states like Arizona. This new study shows that more than 25% of white adults in Arizona were deficient, while black and Hispanic adults had more serious deficiencies of over 57% and over 37% respectively. 

Comment: Deficiencies in Vitamin-D have been linked to the development of prostate cancer as well as other cancers. In my book, Your Prostate, Your Libido, Your Life, I devote an entire chapter to Vitamin D status, sun exposure and prostate problems.

Adults with low serum levels of vitamin D are more likely to have hypertension, diabetes, obesity, and high triglycerides than are adults with higher vitamin-D levels, an analysis of the third National Health and Nutrition Examination Survey (NHANES) shows. Authors of the new analysis say their findings add to growing evidence suggesting it may be time to revisit public-health recommendations for vitamin-D intake.
