Food and asthma


There is emerging evidence that healthy eating may contribute to airway health.123

IgE-mediated food allergies rarely trigger acute asthma.4

Asthma associated with intolerance to food chemicals (non-IgE-mediated reactions) may affect asthma in some individuals, but is probably rare.5 Risk depends on the type of food and the mechanism and degree of the individual’s intolerance.5 Specialist investigation is usually necessary for accurate assessment and diagnosis, which often requires supervised elimination diets and challenge.
