A new study suggests children who eat three or more hamburgers a week may raise their odds for asthma and wheezing.
But the study also found eating a Mediterranean diet rich in fruits and vegetables and fish could cut a child's respiratory risk. That may be because of the antioxidants and vitamins.
Scientists say the burger finding could just be a marker for other lifestyle factors that could boost a child's risk for asthma.
Meat in general was not seen to increase the risk of wheezing.
