A novel New Zealand study examined the association between fast
food and asthma in children. Researchers discovered that the
more fast-food consumed (hamburgers and deep-fried foods) the
higher the incidence of asthmatic signs and symptoms. That study
recorded the frequency of different foods consumed through a
parent questionnaire and measured lung capacity in children
after exercise, then correlated the two. Those researchers found
that the amount of fast-foods consumed corresponded to the
degree of asthma as determined by the change in peak flow
measurements before and after exercise. The correlation between
asthma and foods was true for hamburgers, fried foods (fish and
chips), and fizzy drinks (soda). The higher the dose of these
foods, the more asthma symptoms occurred. The consumption of
other foods was not associated with any outcome, either positive
or negative, in relation to lung function. Those other foods
included meat, fish, vegetables, fresh fruit, and fruit juice.
The authors speculate that th
