What might be one way to ease asthma and eczema in children?

A new report in the British medical journal Thorax suggests cutting back on fast food might help. Researchers studying 319,000 teens in 51 countries found that teens who ate three or more weekly servings of fast food had a 39 percent increased chance of developing severe asthma, while younger children had a 27 percent higher risk. Fast foods contain high levels of trans fatty acids, which are known to affect immune reactions, said the study team, which is led by scientists at the University of Auckland in New Zealand.
