Flags and context, not rated by dose

  • Apple (Fuji), raw

    Worth knowing

    Fernandezrivas 1999 · grade B

    How it’s rated

    Person-specific: apple can cause oral allergy reactions in people allergic to the rose family of fruit. In allergic patients, 'More than 40% ... tolerated the ingestion of the pulp'; reactions occurred only on whole fruit, and peels gave stronger skin-prick, histamine-release and RAST responses. Skin-on is the riskier form for these patients.

    Intake: one 140 g serving a day, 70 kg adult

    Measured on: 33 patients allergic to apple, peach or pear (Fernandez-Rivas 1999)

  • Cherries, raw

    Worth knowing

    PubMed 7930303 · grade B

    How it’s rated

    Person-specific: people allergic to peach often react to cherry through a shared 13 kd allergen (a lipid-transfer-type component); cherry also carries a cherry-specific 30 kd allergen. Mostly oral symptoms in pollen-related cases; systemic reactions in the LTP form. No cherry-specific prevalence extracted.

    Intake: not applicable (person-specific)

    Measured on: Prunoideae cross-reactivity (peach, cherry, apricot, plum)

  • Peaches, raw

    Worth knowing

    PubMed 26633941 · grade B

    How it’s rated

    Person-specific: affects people sensitised to peach lipid transfer protein (systemic reactions in the Mediterranean area) or cross-reactive to birch and other Rosaceae pollen (mostly oral symptoms). No prevalence figure was extracted.

    Intake: not applicable (person-specific)

    Measured on: Peach allergy: Mediterranean lipid-transfer-protein (Pru p 3) allergy and birch-pollen oral allergy syndrome

  • Pears, raw

    Worth knowing

    PubMed 33919631 · grade B

    How it’s rated

    Person-specific: pear is a Bet v 1 cross-reactive food for birch-pollen-allergic people (Pyr c 1); symptoms are usually oral, and the Mediterranean LTP route (Pyr c 3) also exists. A selected, history-positive sample, so not a prevalence.

    Intake: not applicable (person-specific)

    Measured on: Netherlands, birch-pollen-related pear allergy; two varieties (Cepuna, Conference)
