Lychee (also called litchi) is a fruit which only contains one allergenic protein called Lit c 1, it is a profilin protein and is found in significant quantities in the plant.
Lychees are in the Sapindaceae
family of plants. Other plants in this family include maple trees and horse chestnuts.
are involved in the assembly of actin filaments which in plants determine the shape and movement of the cell’s surface.
Profilin proteins are considered to be minor panallergens. They are less commonly associated with allergy than other panallergens, but have become more studied in recent years due to the possibility of cross reactivity.
Lychee is low in histamine, so is suitable to eat if following a low histamine diet.
Lychee is a food moderate in salicylates
. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as food intolerance symptoms in people who are sensitive to salicylates.
You can read more about Food Intolerances
on the dedicated Food Intolerance Page.
Allergy to lychee fruit is sometimes linked to Celery-Mugwort-Spice Syndrome
as the sensitising allergen is a profilin protein called Art v 4, these proteins are also sometimes also called Bet v 2 proteins.
There is a link between lychee and Latex Food Syndrome
. The plant involved in latex allergy Hevea brasiliensis
, the rubber tree plant, has an allergen called Hev b 8 which is a profilin protein. Those very sensitised to latex may have a contact allergic reaction from other foods or plants containing profilin proteins, there is less evidence of this than sensitisation to other latex linked proteins like hevein and chitinases.
Lychee is broadly linked to other fruit profilin allergies. Allergy to celery, peanut, soyabeans, walnut, lupin, almonds, mustard, hazelnut, kiwi, pineapple, chilli, melon, orange, strawberry, apple, banana, aubergine (eggplant), peach, pear, tomato, dates, cherry, carrot, barley and wheat. Allergic reactions to some of these foods may be considered a marker of profilin hypersensitivity.
