March is National Nutrition Month, so it seems appropriate to share new recommendations about vitamin D from the American Academy of Pediatrics (AAP). This new advice, which was presented in the November 2008 issue of Pediatrics, changes the way we think about vitamin D.
Long known to prevent rickets (weakened bones caused by vitamin D deficiency), research now suggests that vitamin D is also related to healthy immune system function and to prevention of diseases such as certain cancers and diabetes. Unfortunately, rickets–an entirely preventable condition for most people–is still being reported in the US, even in teens. While several factors contribute to vitamin D deficiency, our fear of skin cancer could play the biggest role.
Heeding warnings about the link between sun exposure and skin cancer, conscientious parents now prepare for outdoor events by slathering their kids in sunscreen, perching hats on their heads, and confining them to the shade. Vitamin D isn’t found in many unfortified foods, but our bodies can make it from sunshine. Therefore, cloistering ourselves from the sun makes it harder for us to get adequate amounts without using supplements.
In fact, this lifestyle change can even affect children before they’re born, because the fetal vitamin D level is related to the mother’s. Therefore, newborns may be at greater risk for deficiency than we thought. Finally, as kids get older, they tend to eat less of vitamin D-fortified foods, so even teens are at risk for low levels–especially if they don’t get enough sunlight.
The AAP has recommended vitamin D supplements for several years now, but the original recommendation was 200 IU/day to all breastfed infants within the first 2 months of life. The new guidelines increase the recommended amount, begin supplements earlier in life, and address the dietary needs of older children as well. Here are the recommendations in a nutshell:
- Breastfed infants: The AAP now recommends that infants who are exclusively or partially breastfed be supplemented with 400 IU/day of vitamin D beginning in the first few days of life. The supplement should continue unless the baby is weaned to at least 1 quart per day of either vitamin D-fortified formula or fortified whole milk. Check with your doctor for recommendations if you are concerned about your child’s fat intake.
- Nonbreastfed infants and older children: Any child drinking less than 1 quart per day of vitamin D-fortified formula or fortified milk should take a supplement of 400 IU/day.
- Teens: Teens who do not get 400 IU of vitamin D per day through fortified milk or foods should take the supplement as well.
Remember, vitamin D defiency is entirely preventable for most people, and with new evidence that vitamin D may prevent other serious health conditions, it’s important that all parents be aware of the new guidelines. Be sure to work with your child’s doctor to determine the proper supplement amount, since some medical conditions may require different treatment. Also ask your doctor for directions on proper administration of any supplement, to avoid a potentially dangerous overdose. Here are a few handy links–
