Si vous êtes allergique à l’arachide, méfiez-vous aussi du lupin !Jusqu'au début des années 90, le lupin ne se trouvait que dans... les étables ! All four fractions are glycosylated storage proteins. Comme pour les autres allergies alimentaires, l’éviction stricte du lupin de l’alimentation (et de la manipulation si réaction par inhalation) est actuellement le seul traitement possible. « Il semblait pouvoir remplacer l'arachide, car leurs teneurs en protéines et leurs propriétés émulsifiantes sont très proches, explique le Dr Philippe Auriol, allergologue.
These reactions can be severe and life-threatening. Lupin allergy.

Comme d’autres légumes, il peut provoquer des réactions allergiques chez les personnes particulièrement prédisposées. Therefore lupins are now one of the major allergens and must also be indicated as an ingredient on packaged goods. Immunoblotting and ELISA experiments demonstrated IgE binding to all lupin conglutins (alpha, beta, gamma and delta) as well as to peanut and almond proteins, with a unique IgE-binding profile for each patient. En effet, cette plante fourragère de la famille des légumineuses (comme le pois, le soja, la fève, le haricot et l'arachide) était réservée à la seule alimentation du bétail. Surprisingly, lupin allergy is observed more in a country where lupin is not traditionally used, implying that short-term, moderate use of lupin can result in serious allergic reactions (41).

This child was one of six challenged children with IgE antibodies to peanut >15 kU(A)/L.
The numbers are now reclining due to increased attention and the voluntary termination of lupin use in a number of bakeries.Lupin seed storage proteins with high homologies to other leguminous allergens are primarily responsible for eliciting allergic incidents. Lupin allergy occurs by primary sensitisation to ingested lupin protein, sensitisation through inhalation, and occupational exposures. Major seed proteins are α- and β-conglutins, and to a lesser extent gamma- and delta-conglutins. Some people who are allergic to peanuts may also react to lupin. Pour en savoir plus ou exercer vos droits, vous pouvez consulter nos Cupins form a large protein superfamily sharing a β-barrel structural core domain.The major IgE-binding proteins of lupin have molecular weights of approximately 43-45 kDa, which has been shown by immunoblotting in several studies involving lupin-allergic patients. Asymptomatic sensitisation is most frequent, but occasionally, clinical manifestations of allergy can also present (38).
Plus un enfant est exposé tôt à un allergène, plus il risque en effet d'y devenir allergique.
