Calcium Intake Found Too Low in Children and Adolescents

Dec. 2, 1999 (Atlanta) -- Children and adolescents are not receiving enough
calcium, according to a revised policy statement from the American Academy of
Pediatrics that appears in the November issue of the journal Pediatrics.
Calcium-rich foods and beverages, as well as exercise, provide the
Calcium plays several very important roles in development, according to
Susan Baker, MD, PhD, in an interview with WebMD. "The one we probably
focus on the most and know the most about is bone health," she says.
"Currently, we understand that calcium is deposited in bones until early
adulthood. Then, ? we tend to leach calcium from our bones. ? The more calcium
you can have on board for your bones, the less likely you are to have problems
[such as osteoporosis] later on." Additionally, she suggests that, although
the data are not in yet, dietary calcium may play an important role in blood
pressure regulation. Baker is a professor of pediatrics at the Medical
University of South Carolina, in Charleston, and chairwoman of the Committee on
Nutrition at the American Academy of Pediatrics.
Baker says that the problem of children not getting enough calcium is
probably not new. "As we begin to understand calcium needs a little better,
we're finding that probably we underestimated them in some of the
recommendations that were made previously," she says. However, she adds,
there has been a gradual movement away from calcium-rich foods and drinks to
those that have no nutritional benefits for children. She cites sodas as a
While many children erroneously believe that eating dairy products will make
them put on weight, Baker indicates that the behaviors associated with improved
calcium nutrition are the same behaviors necessary to prevent obesity.
"We want [to encourage] healthful foods and beverages and exercise,"
Based on the 1994 NIH recommendations, the American Academy of Pediatrics
recommends that children consume 800 mg per day of calcium. Preteens and
adolescents should consume 1,200 to 1,500 mg per day of calcium.
What are some examples of foods or drinks that are high in calcium?
"Other than milk, or milk-based beverages, there is very little calcium in
anything that is a beverage," says Baker. "Some of the juices are
fortified with calcium. If you have a calcium-fortified juice, you get
approximately the same amount of calcium as is present in milk. In foods, the
most calcium is in dairy products. White beans, broccoli, sardines, and sweet
potatoes have some calcium. [But] you have to be very careful with leafy green
vegetables -- for example, spinach. It does have a lot of calcium, but it's not
in a form that the body can really use."
