Study urges vitamin D supplement for infants

Study urges vitamin D supplement for infants - USATODAY.com: "Most babies should take a daily vitamin D supplement, a new study shows.

That will be a big change for most parents — and even many pediatricians.

Only 1% to 13% of infants under 1 year now get a vitamin D supplement, available in inexpensive drops, according to a study published online today in Pediatrics.

Those drops are needed, the study says, because only 5% to 37% of American infants met the standard for vitamin D set by the American Academy of Pediatrics in 2008: 400 international units a day.

Vitamin D strengthens bone and the immune system and also appears to prevent type 1 diabetes, heart disease and cancer, the paper says.

Few breast-fed babies — 5% to 13%, depending on their age — received the recommended amount of vitamin D, researchers estimated. Although breast milk is the perfect food in every other way, it's often low in vitamin D, says pediatrician Nicolas Stettler, a spokesman for the pediatrics academy who wasn't involved in the study. Because humans originated in equatorial areas with year-round sunshine, babies in the distant past wouldn't have needed to get vitamin D from breast milk, he says."
