Millions of American children aren't getting the minimum amount of vitamin D they desperately need every day to build healthy bones, according to a new study. In fact, these findings support growing evidence that vitamin D levels, particularly among Hispanic and black kids, have dropped to unhealthy norms.
After reviewing health data collected from 2001-06 on 5,000 children, scientists found some 20 percent of all kids had vitamin D levels below the minimums set for children by the American Academy of Pediatrics (50nmol/L).
However, more than two-thirds of the children surveyed had vitamin D levels below 75 nmol/L, the amount some adult studies have suggested as a minimum that lowers the risk of some cancers and heart disease. Using that higher measurement, vitamin D levels among Hispanic and black children dropped like a rock by 80 and 92 percent, respectively.
On the other end of age spectrum, a coalition of European doctors is considering formalizing a standard for vitamin D levels among seniors older than age 75 (albeit a conservative one) that could eventually yield better bone health among all age groups. If you are considering supplementing your diet with vitamin D be sure to chose a formula that contains natural vitamin D3, which helps to increase absorption of dietary calcium while decreasing calcium excretion from the body.
