Courgette is also known as zucchini in the USA, but is also known as marrow and summer squash. Courgettes are grown from the plant Cucurbita pepo
, subspecies of this plant also grow pumpkins
and gourds. They are rarely documented as causing food allergies.
For those that do experience allergies after consuming courgette the allergens responsible are thought to be plant profilins
Allergy to courgette has been linked to Latex Food Syndrome
, this is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.
Courgette allergy is also linked to Pollen Food Allergy Syndrome
for people who suffer from grass allergies. This is where is the body confuses allergens it is sensitised in grass to those it finds in foods.
Those with a sensitivity to latex may have linked allergies to foods which contain high levels of chitinase, like avocado, chestnuts, corn (maize), kiwi, papaya, pomegranate and tomatoes.
If suffering from Pollen Food Allergy Syndrome you may suffer allergy to grass pollen, pumpkins, cucumber and melons.
