Avoidance of food allergens in childhood asthma.

Twenty-four patients of moderate persistent perennial asthma with documented aggravation to severe persistent asthma, during monsoon season in the past two years, were put on specific elimination diet during August and September. The diet was based on results of in-vitro allergy tests for a selected food panel. On specific elimination diet, five patients improved to mild persistent asthma and twelve patients improved to mild persistent asthma with occasional exacerbations . Six patients remained at moderate persistent asthma and only one patient deteriorated to severe persistent asthma. These results indicate that food avoidance may help in asthma control in children.
