Food allergy management: avoidance and label reading
Food allergy management is built on education about the confirmed trigger foods, reading labels, avoiding those foods and an emergency plan.
Remember
Management rests on education, not routine drugs: know the confirmed trigger food, read the ingredients each time, avoid the food, and keep an emergency plan for accidental exposure.
Once a food allergy is confirmed, management is patient-centred, which means it relies on the person's own awareness and education. Avoidance of the confirmed trigger food is the main approach. The patient learns how to read labels and what to do after an accidental exposure.
In the United Kingdom, 14 major allergens (the trigger foods) must be declared on packaged food. When one appears in the ingredients list, patients can find it quickly because it is emphasised, most often with bold type. Even so, the list still needs reading each time, including for a familiar product, because recipes can change. A 'may contain' warning is a voluntary note about possible traces of an allergen, so it is not used to declare one that is an intentional ingredient. How far to go depends on severity: some patients are also advised to avoid possible traces of the food in packaged goods.
Removing extra foods from the diet risks poor nutrition, so a dietitian (a specialist in diet and nutrition) is useful, especially when allergies are multiple or severe.
The patient is given a written, personalised allergy management plan and, if a severe reaction is possible, is also taught to use an adrenaline auto-injector. These form a safety net, but they support avoidance rather than replace it.
Key facts
- Main approach
- avoiding the confirmed food, with education on reading labels and knowing what to do in an accidental exposure.
- UK law
- 14 major allergens must be declared on packaged food, and in the ingredients list they are emphasised, most often with bold type.
- Checking labels
- check the ingredients list each time, even for a familiar product, since recipes can change.
- Traces
- how strict to be depends on severity, as some patients are also advised to avoid possible traces of the food in packaged products.
- Dietitian
- a specialist in diet and nutrition, useful, especially when allergies are multiple or severe, because cutting out foods without a plan can leave nutritional gaps.
- Emergency plan
- a written allergy management plan and, if a severe reaction is possible, an adrenaline auto-injector are a safety net, and they support avoidance rather than replace it.
Exam traps
- A daily antihistamine does not stop exposure and cannot prevent anaphylaxis, so it is no substitute for avoidance.
- A 'may contain' warning is a voluntary note, not the way a food business declares an allergen that it has used as an intentional ingredient.
- A list of brands eaten safely before is not a safe shortcut, because recipes change and so the ingredients need reading every time.
