Tomato Allergy

Key Allergens

There are 7 allergens associated with tomato allergy - the main allergen in tomato is Sola l 4 which is similar in shape to the Bet v 1 allergens which can cause oral allergy type symptoms.

Three of the proteins found in tomato are lipid transfer proteins, Sola l 3, 6 and 7.


You may have Pollen-Food Allergy Syndrome if you suffer from tomato allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.

The lipid transfer proteins in tomato may cause problems if you suffer from LTP Syndrome.

To a lesser extent tomato allergy has been linked to Latex Food Syndrome, which is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.
