London: Gorging on junk food thrice a week may lower immunity in kids, raising their risk of asthma and eczema, according to an international study.

A research project involving more than 50 countries found that teenagers who ate food such as burgers three times a week or more were 39% more likely to get severe asthma. Younger kids were 27% more at risk, The Sun reported. Both were also more prone to the eye condition rhinoconjunctivitis.
