Allergy and Intolerance Prevalance in the UK

  • Approximately 1-2% of adults in the UK have a food allergy and 5-8% of children (Pawankar R et al., 2013)
  • Asthma is prevalent among people with food allergies, which can make reactions more severe if not controlled by medication (Food Standards Agency, 2015)
  • About 1% of people in the UK have coeliac disease (Food Standards Agency, 2016)
  • Each year there are around 20 fatalities from anaphylaxis in the UK (Pumphrey, 2000)
  • 78% of fatalities are people who have also been diagnosed with asthma (Turner et al., 2015)

Food Labelling

The European Food Safety Authority (EFSA) is responsible for monitoring and assessing food allergens across Europe. There are 14 foods which must be labelled and identified as ingredients on all pre-packed food:

  • Cereals containing gluten: wheat, spelt, Khorasan wheat, rye, barley, oats
  • Crustaceans: prawns, crabs, lobster, crayfish
  • Eggs
  • Fish
  • Peanuts
  • Soybeans
  • Milk
  • Nuts: almonds, hazelnuts, walnuts, cashews, pecan nuts, brazil nuts, pistachio nuts, macadamia nuts
  • Celery including celeriac
  • Mustard
  • Sesame
  • Sulphur dioxide/sulphites – where added and at a level above 10mg/kg in the finished product. This can be used as a preservative in dried fruit
  • Lupin: lupin seeds, flour, can be found in types of bread, pastries and pasta
  • Molluscs: clams, mussels, whelks, oysters, snails

IgE Testing

When testing for food allergies, we use an approved testing system which measures an IgE reaction. IgE is an antibody that reacts when exposed to an allergen. Your sample is exposed to a number of food and non-food items to determine the substances that would trigger an inflammatory response in your body were you to ingest or come into contact with it. A response would trigger symptoms in your body.

The NHS use IgE blood testing as well as skin prick tests, patch tests and food challenge testing to diagnose allergies.

IgG4 Testing

We use a globally recognised technique, the ELISA method. This involves looking for a raised IgG4 reaction. IgG4 is an antibody which your body produces to deal with a perceived threat. In cases of intolerance, your body is perceiving the substance to which it is intolerant as a potential threat causing an inflammatory response or the symptoms you’re experiencing.
