More about Food Allergies


Food intolerances remain an area of research due to the diversity of complaints, severity of symptoms and the increase in reporting of cases worldwide.

We’ve put together our list of TMI Testing food intolerance facts based on our 10+ years of working with nutritional therapists, helping people with intolerances identify triggers and assisting clients with elimination diets.

The understanding of food intolerances and to a certain extent allergies is growing all the time and evolving with further scientific research.

Common food allergens

Almost any food can potentially cause an allergic reaction, but there are certain foods that are responsible for most food allergies.



Cereals containing gluten: wheat, rye, barley, oats


Crustaceans; prawns, crabs, lobster, crayfish, etc




Nuts; almonds, hazelnuts, walnuts, cashews, brazil, etc


Celery (including celeriac)


Molluscs like clams, mussels, whelks, oysters, snails and squid


Meats: some people are allergic to one type of meat and others to a range of meats; a common symptom of meat allergy is skin irritation.

Types of food allergies

There are 3 types of food allergy.


IgE-mediated food allergy which is the most common, triggered by an immune response producing an antibody called immunoglobulin E (IgE). Symptoms occur a few seconds or minutes.

Non-IgE-mediated food allergy is an allergic reaction not caused by immunoglobulin E, but by other immune cells. This is often difficult to diagnose as symptoms take much longer to develop (up to several hours).

Mixed IgE and non-IgE-mediated food allergies can occur in some people.
