Give Your Children a Calcium Boost
Get to know more calcium-rich foods for stronger bones
The calcium we get in childhood is important for normal growth, developing strong bones and teeth, and ensuring healthy bones later in life
Children’s diets are notorious for their lack of fruits and vegetables and for their abundance of highly processed, high-sugar, high-fat, high-calorie foods—so it might come as no surprise that their diets come up short in important nutrients, including calcium. A new study found that children between ages 4 and 18 don’t get enough calcium, and much of what they get is from high-fat dairy foods like ice cream and cheese.
Children are coming up short
Calcium is the most abundant mineral in the body, and although 99% of it is in the bones and teeth, it plays a critical role in the normal functioning of all body cells. The calcium we get in childhood and adolescence is important for normal growth, developing strong bones and teeth, and ensuring healthy bones later in life, when low bone density (osteoporosis) can lead to high fracture risk.
The new study looked at the amount of dairy consumed by 2- to 18-year-old children and compared it to amounts recommended by the US Department of Agriculture’s (USDA) “MyPyramid” and the Institute of Medicine’s levels for Adequate Intake (AI).
Children from two to three years old met guidelines of 2 portions of milk per day (or the equivalent amount of nonmilk dairy foods), but none of the other age groups got the 2 to 3 portions per day recommended for children their age.
High-fat dairy foods accounted for one-half of younger children’s dairy intake and more than one-third of older children’s dairy intake. Children from two to eight years old were getting the recommended amount of calcium (500 to 800 mg per day), but 9 to 18 year olds did not get the recommended 1,300 mg per day.
Calcium sources—dairy and beyond
Institutions that make and promote public health policies recommend eating plenty of dairy foods for calcium, and according to the researchers of this study, “focusing nutrition guidance efforts on increasing the intake of the low-fat dairy products, with special emphasis on increasing calcium intake in school-age children and adolescents through flavoured low-fat milk products, may be beneficial." Diets heavy in whole dairy, however, raise some concerns, because many—such as ice cream and flavoured milk and yoghurt—have lots of added sugar, and others—such as most cheeses—are high in saturated fat. Some people are unable or choose not to eat dairy foods, and for them, other options can be just as healthy.
For nondairy calcium sources, consider introducing some of the following foods into your family’s diet:
“I try to encourage people to eat and feed their children a very rounded diet, and not to rely solely on dairy for calcium,” said Julianne Forbes, a naturopathic doctor who does nutritional work with children and adults. “Cooking green vegetables helps increase the availability of their calcium, and using a little vinegar on them increases calcium absorption. Not all children will eat greens, but parents can keep trying, offering other things they might like, such as nori and other seaweeds, sweet potato, toasted sesame seeds, tofu, and figs.”
She also pointed out that getting enough vitamin D—from sun exposure and dietary sources such as cod liver oil—is critical for good calcium absorption and, therefore, strong bones.
