Teens Lacking in Vitamin D

Many teens aren't getting enough vitamin D, according to research published in 2004 in the Archives of Pediatric and Adolescent Medicine. Vitamin D deficiency is an easy problem to solve because the skin produces vitamin D when exposed to the sun, and foods such as milk and cereal are enriched with vitamin D. But many teens pass up milk for soft drinks and spend their free time indoors with computers or television, the study found.
