The threat from fast food may be growing larger. A new study of hundreds of thousands of kids and teens worldwide finds the stuff is associated with a higher risk of asthma, rhinitis, and eczema, Time reports. Fortunately, there's a simple path to some protection: Eat more fruit. Researchers in Europe surveyed more than 319,000 teens ages 13 to 14 across more than 50 countries, as well as more than 181,000 children ages six to seven.
Kids and their parents answered questions about their diets and their asthma, allergy, and eczema symptoms. The researchers found a 39% higher risk of severe asthma among teenagers who ate fast food three or more times per week; among the younger group, the risk was raised 27%.
