WhyPeanut and tree nuts: strict filtering, no guessing.

4 things we do specifically.

Low GI

Glycemic index free by default.

A peanut / tree nut allergy does not call for any particular GI profile. Our low-GI filter is optional: you turn it on if you have another condition (T2 diabetes, cholesterol) declared on top of it.

Macros

Macro ratio free by default.

No specific macro constraint. The allergen filter layers on top of your other settings (diet, weight-loss/maintenance goal). You are not required to combine them: the allergy alone = the allergen filter alone.

Portions

Portions free by default.

Portions follow your energy goal with no constraint tied to the allergy. The filter works at the ingredient level, not the quantity level. The allergy is a category filter, not a size one.

Substitutions

Substitutions nut-free, peanut-free.

For every recipe that contains pine nuts, almonds, walnuts, cashews or peanuts, we suggest a tested swap (pumpkin seeds, toasted sunflower seeds, sesame seeds). Never a cross-swap toward another tree nut.

Foods to avoid strictly

  • Peanut · peanuts, peanut butter, unrefined peanut oil, satay, some infant formulas
  • Tree nuts · almond, hazelnut, walnut, cashew, pecan, Brazil nut, pistachio, macadamia nut
  • Traces and cross-contamination · "may contain", "made in a facility that...", chocolates, pastries, Asian dishes
  • Pestos and sauces · classic pesto (pine nuts), satay sauce, some enriched hummus
  • Prepared dishes without clear labelling · vigilance in canteens and caterer dishes

Tracked parameters

  • Allergy work-up · specific IgE, prick tests, logged yearly or as prescribed
  • Individual Care Plan (PAI) · for children at school, tracking of renewals
  • Adrenaline auto-injector · expiry date, training on its use
  • Eating out · log of any incidents, shared with your allergist
  • Cross-reactions · pollen-fruit (oral syndrome), latex-fruit, to explore with your allergist

The 14 EU mandatory-declaration allergens

INCO Regulation (EU) 1169/2011: 14 allergens must be declared on labels and on restaurant menus across Europe. Peanut and tree nuts are among them (two separate entries). The app applies the category filter: if you declare a peanut allergy, no recipe containing that ingredient or its derivatives will ever be suggested to you.

Cross-contamination

This is the common trap. A kitchen that prepares a dish with peanut contaminates the crockery, the utensils, the oil. For some severe allergies, traces trigger an anaphylactic reaction. The app suggests recipes designed without cross-contamination (dedicated utensils, order of preparation). For the restaurant, we provide a multilingual card to show the staff.

Eating out

The app includes a restaurant card to show the staff (in French + English + 12 other EU languages) that explains your precise allergy, the anaphylactic risk, and the cross-contamination warnings. More effective than explaining it every time.

Cross-reactions: to explore with your allergist

Some people allergic to peanut also react to tree nuts (cross-allergy), to soy, or to legumes. These crossovers cannot be guessed: an allergy work-up identifies them. The app lets you tick each allergen individually based on your diagnosis.

Not a medical device

The app does not replace your allergist. It complements. The diagnosis (prick tests, specific IgE, oral food challenge in a hospital setting), the prescription of an adrenaline auto-injector, and the PAI (Individual Care Plan for children at school) remain their domain.

Not a medical device

Diagnosis, treatment and follow-up of any condition remain the responsibility of your doctor and specialist. Budday complements, never replaces.

Recipes and tracked parameters are indicative, based on public recommendations (HAS, ANSES, specialised learned societies).

Frequent questions

What we get asked the most.

Still looking for an answer? Write to us.
Is this adaptation permanent?
As long as your condition stays declared in your profile, yes. Recipe filtering, macro calibration, substitutions, all of it keeps applying without you having to restate it. You can switch it off whenever you want in Settings.
Do you replace my doctor?
No. Budday is not a medical device: we complement, we never replace. Diagnosis, treatment and clinical follow-up stay with your doctor and your specialist. We help you apply their guidance day to day.
What if I have several conditions to manage?
We combine them without breaking anything. Type-2 diabetes + gluten-free, cholesterol + lactose intolerance, tree-nut allergy + vegetarian: every combination is handled at once in the menu calibration and the swaps we suggest.
Your sources, what are they?
For each condition: public guidelines from HAS, ANSES, learned societies (Société Francophone du Diabète, AFDIAG, and more) and recent peer-reviewed studies. No isolated opinion, no sponsored advice. The sources are cited on every condition page.
