Phase 3 of the International Study of Asthma and Allergies in Childhood looked at how food affects the risk of developing allergic diseases such as asthma, rhinoconjunctivitis, and eczema.
The researchers found that children who ate fruit more than 3 times a week were less likely to suffer from severe asthma, while those who ate fast food more than 3 times a week had an increased risk of severe asthma, rhinoconjunctivitis, and eczema.
The research did not address whether the food was a cause of the increased risk or merely an interesting correlation.
