Slice a banana to top junior’s oatmeal or pack a whole one in your girl’s Hello Kitty® lunch box. New research from the Imperial College London shows that kids who ate one banana a day had 34% less chance of developing asthma symptoms.

Researchers collected dietary information from 2,640 children, aged 5–10, and found that banana eaters were one-third less likely to encounter breathing problems such as wheezing. Children who drank apple juice daily experienced a 47% reduction in asthma symptoms.

Outcomes from the same study, which was funded by Dole®, suggest that kids with low fiber intake are more vulnerable to respiratory problems associated with secondhand smoke.
