Quick answer
Food allergy, food intolerance and coeliac disease are different conditions, but each can require accurate food information and careful preparation. Food staff should understand the distinction without diagnosing customers or deciding a safe amount for them. Confirm the specific ingredient to avoid and follow the business’s information, preparation and emergency procedures.
Understand the terms without giving a diagnosis
The NHS explains food allergy as the immune system overreacting to a food. Reactions vary and can be serious. Its food-intolerance guidance describes difficulty digesting a food or ingredient, which is different from an allergic reaction.
The NHS describes coeliac disease as an autoimmune condition triggered by gluten that damages the small intestine. It is not simply another name for wheat allergy or a dietary preference. Diagnosis, treatment and individual dietary advice belong to qualified health professionals.
Focus on the operational question
| Situation | A useful operational response |
|---|---|
| A customer identifies a food allergy | Clarify the specific food or ingredient and check reliable current information and preparation capability. |
| A customer identifies an intolerance | Take the request seriously and establish the ingredient to avoid; do not dismiss it or prescribe an acceptable quantity. |
| A customer says they have coeliac disease | Use reliable gluten-related information and the business’s appropriate preparation controls; do not equate “no wheat ingredient” with a verified gluten-free claim. |
| The customer’s wording is unclear | Ask a respectful clarifying question and involve the authorised person rather than guessing the condition. |
The conversation is about what the business can accurately provide. Staff do not need to test the customer’s diagnosis or ask for private medical evidence to answer an ingredient question.
Avoid unsafe shortcuts between labels
A product described for one dietary purpose may not meet another requirement. A wheat-related allergy question and a gluten-free claim need their own accurate information. A plant-based description also does not establish absence of milk, nuts, soya or other allergens through ingredients or transfer.
Illustrative example: a customer asks whether a replacement ingredient meets their stated need. The correct response is to check the actual ingredient evidence and explain the preparation conditions, not assume that a label intended for a different dietary group settles the question. Keep the customer’s own decision informed by accurate facts.
Use a reliable information and service chain
Record the request accurately, check current ingredients and components, communicate it to preparation staff and identify the correct meal at handover. Explain a limitation before the order is accepted if the business cannot provide reliable information or the necessary control.
Use the existing regulated-allergen guide for the declaration groups and the allergy-order handover guide for service steps. The regulated list does not mean a customer cannot react to a different food.
Recognise the emergency boundary
Do not diagnose the seriousness of a developing reaction from the name of a condition or a previous reaction. If someone appears to be having a serious allergic reaction, follow the setting’s emergency procedure and current NHS instructions; call 999 for the serious warning signs described by the NHS and follow the operator’s advice.
Routine food staff should not improvise treatment or tell someone that a symptom is “only intolerance”. The purpose of this guide is to support accurate food handling and communication, not to replace medical assessment or an individual healthcare plan.
Next steps
