Children, Teens Advised to Double Vitamin D Intake

(Reduction of disease risk cited)

The nationís leading pediatricians group says children from newborns to teens should get double the usually recommended amount of vitamin D because of evidence it may help prevent serious diseases.


To meet the new recommendation of 400 units daily, millions of children will need to take daily vitamin D supplements, the American Academy of Pediatrics said.  That includes breast-fed infants Ė even those who get some formula, too, and many teens who drink little or no milk.


Baby formula contains vitamin D, so infants on formula only generally donít need supplements.  However, the academy recommends breast-feeding for at least the first year of life, and breast milk is sometimes deficient.


Most commercially available milk is fortified with vitamin D, but most children and teens donít drink enough of it Ė four cups daily would be needed Ė to meet the new requirement, said Dr. Frank Greer, the reportís co-author.


The new advice is based on mounting research about potential benefits from vitamin D besides keeping bones strong, including suggestions that it might reduce risks for cancer, diabetes and heart disease.  But the evidence isnít conclusive, and thereís no consensus on how much of the vitamin would be needed for disease prevention.  The new advice replaces a 2003 academy recommendation for 200 units daily.


Thatís the amount the government recommends for children and adults up to age 50, while 400 units are recommended for adults aged to 71 and up.  Vitamin D is sold in drops for the youngest children, in capsules and in tablets.


The Institute of Medicine, a government advisory group that sets dietary standards, is discussing with federal agencies whether those recommendations should be changed based on emerging research, said spokeswoman Christine Stence.


The recommendations were prepared for release Monday at an academy conference in Boston.  They are to be published in the November issue of the academyís journal, Pediatrics.


Besides milk and some other fortified foods like cereal, vitamin D is found in oily fish including tuna, mackerel and sardines.


But itís hard to get enough through diet; the best source is sunlight because the body makes vitamin D when sunshine hits the skin.


While it is believed that 10 to 15 minutes in the sun without sunscreen a few times weekly is sufficient for many, people with dark skin and those in northern, less sunny climates need more.  Because of sunlightís link with skin cancer, ďvitamin D supplements during infancy, childhood, and adolescence are necessary,Ē the academyís report say.


Recent studies have shown that many children donít get enough vitamin D, and cases of rickets, a bone disorder often associated with malnourishment in the 1800s, continue to occur.
