I’d like to share this informative article from The New England Journal of Medicine on Vitamin D Deficiency
Children and young adults are also potentially
at high risk for vitamin D deficiency. For example,
52% of Hispanic and black adolescents in a study
in Boston and 48% of white preadolescent girls
in a study in Maine had 25-hydroxyvitamin D
levels below 20 ng per milliliter. In other studies,
at the end of the winter, 42% of 15- to 49-year-old
black girls and women throughout the United
States had 25-hydroxyvitamin D levels below 20 ng
per milliliter, and 32% of healthy students, physicians,
and residents at a Boston hospital were
found to be vitamin D–deficient, despite drink-
ing a glass of milk and taking a multivitamin
daily and eating salmon at least once a week.
I saw an interesting image in the National Geographic a year or two ago of a Russian physician treating a room full of children with ultra violent light during the long dark Winter. This was being done due to the obvious lack of sunlight exposure, Vitamin D is produced by your skin in response to exposure to ultraviolet radiation from natural sunlight.
