Pollen-food syndrome (PFS) are often thought to be a minor cross-reacting food allergy solely affecting Northern Europe. In contrast, lipid transfer protein (LTP) allergy is thought to be more severe and primarily impacts Southern Europe. With an emphasis on reaction intensity, researchers sought to inform about both types of plant food allergies and assess if their stereotypical manifestations have not changed.

According to recent research, both of these plant food allergies can affect children and adults. Although PFS allergy and LTP allergy are more common in Northern Europe and Southern Europe, these disorders are not geographically restricted, and the distribution and allergenicity of pollen owing to global warming continue to affect how they manifest. Both illnesses range in intensity, with PFS sometimes exhibiting more severe symptoms, including anaphylaxis, and LTP allergy exhibiting less severe responses.

It was crucial to remember that in many regions of Europe, responses to plant foods, especially fruits or vegetables, may be caused by either primary sensitization to LTP allergens or pollen cross-reactivity. A thorough clinical history and pertinent testing will benefit everyone presenting with plant foods symptoms to make an accurate diagnosis and execute the proper therapy.
