Vitamin D is a nutrient that 70 percent of American children are deficient in, according to a 2009 report by CNN. The American Academy of Pediatrics doubled its intake recommendations for children in 2008. A deficiency in vitamin D plays a role in many health conditions that are easily prevented by ensuring your child is getting adequate supplies from her diet and through supplements.
Daily Recommended Intake
Babies in their first year of life should be getting 400 IU of vitamin D each day. Children ages 1 to 19 need 600 IU daily. If you are concerned about your child's intake, his doctor can perform a simple blood test to measure what his levels are. This can help you determine if a supplement is necessary.
Role In A Child's Health
There are many reasons why getting enough vitamin D is necessary during childhood. It helps your child absorb calcium from her food, which strengthens bones and teeth. Your child's nerves use vitamin D to carry messages throughout her body and for healthy muscle function. Vitamin D also supports your child's immune system by fighting bacteria and viruses that could make her ill. Some studies have indicated that vitamin D could play a role in preventing chronic diseases in adulthood, including heart and immune problems, reports HealthyChildren.org. Cancer and high blood pressure are other health conditions that vitamin D may be able to prevent.
Deficiencies
One of the largest concerns associated with a vitamin D deficiency in childhood is rickets, which occurs when bones become soft and brittle. This condition is more common in African American children, according to the Office of Dietary Supplements. Breast-fed infants are also at an increased risk of a deficiency and most doctors recommend a supplement if you are nursing exclusively. Children with cystic fibrosis or who are taking certain medications may also need additional vitamin D to prevent becoming deficient.
Food
Adding foods that contain vitamin D to your child's diet is a healthy way to increase his intake. Most milk sold in America is fortified with vitamin D as are many breakfast cereals. Salmon, tuna and mackerel contain vitamin D as well as having heart and brain benefits. Cheese, egg yolk and mushrooms also contain vitamin D. If your child is a picky eater, talk with his doctor about a supplement. Too much vitamin D can cause digestive and heart issues so be sure your child is not getting too much through supplements and food.
Sunlight
Your child's body makes vitamin D when it is exposed to sunlight. However, with the rise in sunscreen use among children, this may not be contributing to her levels. Limiting your child's exposure to the sun decreases her risk of skin cancer. It is much safer to give her a daily vitamin D supplement and offer foods that contain this nutrient.
