Fast Food May Contribute to Asthma in Children

Posted: Updated:

A Canadian study finds children who eat fast food more than once or twice a week seem to have an increased risk of developing asthma.

Researchers aren't sure why fast food may contribute to asthma -- but suggest it could be the high levels of fat and sodium in the food.

They say nutrition is likely only one of many factors involved in asthma.

Researchers also say large amounts of fast food consumption appears to erase all of the benefits that breast-feeding gives in protecting against the respiratory disease.

In this particular study, more than half the children studied, ate fast food more than twice a week.
