Lupin Allergy

Definition

Immunological reaction to lupin proteins, a legume increasingly used as an ingredient in gluten-free products. This allergy may exhibit cross-reactivity with peanut.

How it works

Lupin allergy is an emerging allergy linked to the increasing use of lupin as a protein source in gluten-free and peanut-free products. Lupin is a legume that can trigger allergic reactions in sensitized individuals. A cross-reaction is possible in individuals allergic to peanuts or other legumes. Symptoms may be varied and the allergy can manifest suddenly. Correct identification of products containing lupin is essential.

Role

Lupin provides proteins and fibers as a gluten-free alternative but causes an immunological reaction in allergic individuals.

Examples

• Lupin flour
• Gluten-free baked goods
• Lupin pasta
• Lupin-based snacks
• Protein supplements
• Certain enriched dairy products

Recommendations

Search for lupin on gluten-free product labels and check possible cross-reactions with peanuts. If you are allergic to legumes, be particularly vigilant and consult an allergist to confirm.

Key takeaway

Lupin allergy requires attention to gluten-free products and vigilance towards cross-reactions with legumes.
