The role of food reactions in asthma has not been well described The o
bjectives of this study were to evaluate the types of self-reported re
actions to foods in asthmatic patients, and to determine the associati
on between self-reported food reactions and self-reported severity of
asthma and asthma health care utilization. We characterized 914 patien
ts, aged 3-55 years, in a large health maintenance organization. We ch
aracterized the patients according to demographic data (age, sex, occu
pation, SES, marital status) and their asthma according to duration, t
riggers, severity (symptoms, FEV1 percentage predicted) and presence o
f atopy. Overall, 414 (45.3%) participants, primarily women, reported
adverse reactions to food particularly milk, red wine, eggs, chocolate
, and peanuts. Those with food reactions were more likely to report ha
ving ever been hospitalized for breathing problems than those without
food reactions (31% vs. 22%, two-tailed p = 0.004) although their asth
ma was not worse. Self-reported food reactions, particularly in female
s, may be associated with increased asthma health care utilization, an
d such patients may require closer health care management.
