A new study finds that kids with celiac disease (CD) need certain vitamins in their diets to stave off weak bones and osteoporosis.

Researchers looked at 43 children and teens with CD between the ages of 3 and 18 and found that many also tended to have low bone density, likely due to poor intake and absorption of vitamins and minerals.

The study revealed that the children were getting less than 50 percent of their recommended dietary intake of vitamin K, and that they also suffered from low levels of vitamin D, which can be raised through increased exposure to sunlight and by eating fortified dairy products.

"Children with celiac disease are at risk for poor bone health, but by adding vitamins K and D to their diets, it can help reduce the risk of fractures and osteoporosis," said the study’s Diana Mager.

CD is a lifelong digestive disorder affecting children and adults. When people with CD eat foods that contain gluten, it creates an immune-mediated toxic reaction that causes damage to the small intestine and does not allow food to be properly absorbed.

There is no cure for CD, although it can be managed through diet.
