Paediatric respiratory reviews

Food allergy and asthma are both atopic diseases and therefore frequently co-exist. Food allergy is common in childhood, affecting approximately 8% of infants. The diagnosis is based on a suggestive history supported by skin-prick testing, serum specific IgE or food challenge. ⋯ The mechanism underlying this connection is unclear. The co-existence of food allergy should be considered in any child with asthma. Where food allergy is confirmed, steps should be taken to avoid these foods as this may considerably improve asthma control.
