Tartrazine Exclusion for Allergic Asthma

Tartrazine challenge or avoidance do probably not alter asthma outcomes, but paucity of evidence prevents firm conclusions. Level of evidence: "C"

A Cochrane review [Abstract] 1 included 6 studies with 570 patients. In none of the trials did tartrazine (a food colorant) challenge or avoidance in diet significantly alter asthma outcomes
