Journal of Allergy and Clinical Immunology, 1975. Sep;56(3): 215-21
The authors presented their evidence that in aspirin intolerance there are two mechanisms – one causing bronchospasm (breathing difficulty such as in asthma) and the other causing urticaria (hives).
They also discussed the cross-reaction between aspirin and tartrazine (Yellow 5), and conducted a double-blind study to determine how often this happens. They found that 15% of the 40 aspirin-intolerant subjects reacted to tartrazine, while none of the controls did.
NOTE: The authors estimated (in 1975) that the maximum per capita ingestion of Yellow 5 was 16.3 mg per day; nevertheless, in their own study they used only 0.22 to 0.44 mg — in other words, the most they used was 1/40th the amount they knew may be actually encountered by real people. Even so, 15% of their subjects had reactions!
QUOTE: “The fact that the type of symptom produced by tartrazine was similar to that produced by aspirin may mean that the same type of biochemical abnormality may be present. … However, the molecular structure of tartrazine is vastly different than that of aspirin …”
