Even If You Live in Sub Tropical Environments You Can Be Vitamin D Deficient
Posted by Tan Man on March 27, 2008
Vitamin D deficiency has been observed among many populations in the northern United States. But few studies have examined the prevalence of vitamin D deficiency in areas of high sun exposure, such as Arizona.
A new study has shown adults in southern Arizona are commonly deficient in vitamin D, particularly those with darker skin who produce less vitamin D in response to sunlight.
More than a quarter of Arizona adults tested had dangerously low blood levels of the vitamin.
