Managing My Food Allergy

On this page you will find information about food allergy, including the symptoms of food allergy and resources to help manage it. We have Factsheets available to help you work out whether you have a food allergy or food intolerance and we can also provide support when it comes to identifying your food intolerance. You can find all of our Factsheets at the bottom of this page.

Types of Food Allergy

Types of Food Intolerance

What is Food Allergy?

Food allergy is caused when the body mistakenly makes an antibody (IgE) to 'fight off' a specific food. When the food is next eaten (or sometimes is just in contact with the skin) it triggers an immune system response which results in the release of histamine and other substances in the body.

These cause various symptoms, depending on where in the body they are released. Very rarely the immune system chemicals are released throughout the body, causing a 'systemic' reaction (such as anaphylaxis).

Food Allergy Labelling?

All pre-packaged food must show a list of ingredients which clearly identifies all the ingredients. There are different regulations for foods that are not pre-packaged and which are prepared on-site in smaller food businesses e.g. a café/sandwich shop/deli. There is still a requirement to provide information on the ingredients and allergen content but how this information is shared is up to the individual business.

They may choose to provide this information in a written form, for example on a chalk board, or they may communicate the information verbally. Further information on legislation regarding food labelling can be found here.

What Is the Difference Between Food Allergy and Food Intolerance?

Food allergy is quite uncommon and normally causes symptoms within a few minutes of eating the offending food or being in contact with the relevant substance. Food intolerance (non-allergic hypersensitivity) is much more common. The onset of food intolerance symptoms is usually slower and may be delayed by many hours after eating the offending food; the symptoms may also last for many hours, even into the next day. Some common food intolerances include lactose intolerance; gluten intolerance and histamine intolerance.

You can find more information about the differences in our downloadable Food Allergy or Food Intolerance? Factsheet.

Food Allergy or Food Intolerance can affect you when going out for a meal. Find out information about the top 14 food allergens.
