What is a food allergy?

Food allergies involve the body’s immune system. The body reacts to certain allergens in food by producing antibodies, which can cause immediate and severe symptoms such as swollen lips or eyes, vomiting, skin hives and, in the most extreme cases, difficulty breathing and a severe fall in blood pressure (anaphylactic shock).

Foods that may cause an allergic reaction include nuts, peanuts, fish, shellfish, eggs, milk, wheat and soya.

What is a food intolerance?

This does not normally involve the immune system, and symptoms may not be as immediate or severe as in food allergies. Symptoms may include headache, fatigue and digestive problems. An example is lactose intolerance, in which certain people cannot digest the sugar in milk.

Food intolerance is harder to diagnose than allergy. The only reliable way to diagnose it is to cut out the suspected food from the diet to see if symptoms get better. If symptoms improve, the food should be reintroduced and monitored for signs of the symptoms returning. This process should only take place under the supervision of a registered dietitian.

When you are making or preparing food for a family member of guest who has a food intolerance or allergy you will need to ensure you do the following:

  • To avoid cross-contamination, store foods such as nuts, peanuts, flour and milk separately in closed containers.
  • Always wash your hands thoroughly and avoid touching other foods until you have finished preparing the meal.
  • Wash all cooking equipment thoroughly with hot water and soap. This includes work tops, chopping boards, mixing bowls, pans, cake tins, knives and utensils.
  • If you are using oil for cooking, do not use oil that food has Previously been cooked in.
  • See our product Guidance Lists for people with food allergies and food intolerances to identify foods and ingredients that are suitable to buy.
