Focus on food allergies and food allergens
October 1st 2021 was a landmark day for people living with a food allergy. New government legislation, referred to as ‘Natasha’s Law’, requires all foods which are prepared and packed on the same premises from which they are sold to have full ingredients listed on the label, with the 14 major allergens emphasised for easy identification. (known as PPDS – Prepared and Packed for Direct Sale).
This legislation comes after the tragic death of teenager Natasha Ednan-Laperouse, who died from an allergic reaction caused by an ingredient in a baguette bought at a food outlet at Heathrow Airport in 2016. At the inquest into Natasha’s death the Coroner stated that the current legislation was not adequate and requested a review.
In the UK, 40% of children have been diagnosed with an allergy. The four most common allergies in children are food allergy, eczema, asthma, and hay fever. Allergy symptoms can affect all aspects of a child’s day to day life, including their health and wellbeing, education, and social activities.

Do you know the difference between a food allergy and a food intolerance?
What is a food allergy?
An allergy is the response of the body’s immune system to normally harmless substances, such as pollens, foods, and house dust mite. Whilst in most people these substances (allergens) pose no problem, in allergic individuals their immune system identifies them as a ‘threat’ and produces an inappropriate response. This can be relatively minor, such as localised itching, but in more severe cases it causes anaphylaxis, a condition which can lead to upper respiratory obstruction and collapse and can be fatal.
The most common causes of allergic reactions are:
- Pollen from trees and grasses
- Proteins secreted from house dust mites
- Moulds
- Foods such as peanuts, tree nuts, milk and eggs
- Pets such as cats and dogs, and other furry or hairy animals such as horses, rabbits and guinea pigs
- Insects such as wasps and bees
- Medicines (these may cause reactions by binding to proteins in the blood, which then trigger the reaction).
What are the symptoms of food allergy in babies and children?
Mild to moderate symptoms typically affect the skin, the respiratory system and the gut.
- A flushed face, hives, a red and itchy rash around the mouth, tongue or eyes. This can spread across the entire body
- Mild swelling, particularly of the lips, eyes and face
- A runny or blocked nose, sneezing and watering eyes
- Nausea and vomiting, tummy cramps and diarrhoea
- A scratchy or itchy mouth and throat.
Severe symptoms (anaphylaxis). These require urgent medical attention.
- Wheezing or chest tightness, similar to a severe asthma attack
- Swelling of the tongue and throat, restricting the airways. This can cause noisy breathing (especially on breathing in), a cough or a change in voice
- A sudden drop in blood pressure (called hypotension) leading to shock
- Dizziness, confusion, collapse, loss of consciousness and sometimes coma.
Anaphylaxis is a life threatening severe allergic reaction. It is a medical emergency, and requires immediate treatment. A severe allergic reaction can cause an anaphylactic shock and must be treated with an Auto-Adrenaline Injector (Epipen). You must have received training to use this on a child (training is now normally part of paediatric first aid)
Treatment for Anaphylaxis
- Call 999/112 for emergency help
- Lay the casualty down
- The child may carry an auto-adrenaline injector (Epi-Pen)
- The injector can save a life if given promptly
What is food intolerance?
Some people experience adverse reactions caused by food. Finding out which foods are causing symptoms can be straightforward for some people and incredibly tricky for others – dependent on what their symptoms are, how quickly the symptoms appear after eating the food and which food (or foods) is causing a problem.
Food intolerances can take some time to diagnose. Although not life threatening, food intolerance can and often does, make the sufferer feel extremely unwell.
