Dr. Joel Finkelstein of Harvard Medical School and colleagues found that 57% of 290 patient admitted to Massachusetts General Hospital were low in vitamin D. Not only were persons either housebound or over age 65 experiencing the deficiency, but 42% of the 77 healthy, non-elderly people with an average age of 44 were likewise affected. The study raises the possibility that recommended intakes of vitamin D are too low — the government’s RDA for vitamin D was just raised in 1999.
