Food allergies: safe avoidance, complete nutrition
A food allergy requires strict avoidance of the allergens identified by your doctor or allergist. Built well, this avoidance stays varied and complete: the support secures your exclusions, sets up nutritional equivalences and prevents deficiencies.

In case of a severe reaction (breathing difficulty, swelling of the face or throat, faintness), call 112. Your allergist's emergency plan always takes precedence.

Complete avoidance of major allergens, a diet without deficiencies
Pointers for safe avoidance
Systematic reading of ingredients and allergen statements, including hidden sources.
Work surface, utensils and meals organised to avoid cross-contamination.
Equivalences per allergen: calcium without milk, protein without egg, fibre without wheat.
The list of your allergens is established by your allergist; dietetic support builds on that diagnosis.
Allergy or intolerance: two different mechanisms
An IgE-mediated food allergy triggers an immunological reaction that can be severe, sometimes from a very small amount of allergen. Intolerance most often stems from an enzyme deficiency or malabsorption: it affects comfort but is not life-threatening. The two situations call for different approaches.
Avoidance in everyday life
Avoidance does not stop at the plate: it runs through labels, the kitchen, the canteen, restaurants and travel. Spotting allergens and cross-reactions (for example between pollens and foods) is part of the work done with you, in coordination with your allergist.
- Label reading and spotting hidden allergen sources
- Organising the kitchen to avoid cross-contamination
- Pollen-food cross-reactions: recognising the families involved
- Restaurants, canteens, travel and family meals
- Coordination with your allergist or GP
Preventing deficiencies
Every excluded allergen must be replaced with nutritional equivalents: calcium and vitamin D when milk is excluded, protein when egg is, fibre and B vitamins when wheat is, good fats and energy when peanut or tree nuts are. This equivalence work is built in consultation, with foods actually available in Luxembourg.
CNS coverage
Food allergy is not listed as such among the Annex E conditions; consultations remain possible privately. Coverage may apply with a compliant prescription for certain conditions in the annex, such as coeliac disease.
What belongs to your physician
Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.
Frequently asked questions about food allergies
They can: some people allergic to a pollen also react to foods of closely related families (for example birch and stone fruits). The link is assessed by your allergist; the concrete dietary adaptation is then done in consultation.
Through precise equivalences, food by food: calcium-enriched drinks for milk, other proteins for egg, naturally gluten-free grains for wheat. The list is built from your habits, not a standard menu.
