Food Allergens

It’s easy to get confused between allergies and intolerances.  Let’s try to clear it up and simplify the whole thing!

The information and guidance below is drawn from Allergy UK, the NHS and the Food Standards Agency websites , which you can find by clicking on their links at the bottom of the page


What is food allergy?

Food allergy is caused when the body mistakenly makes an antibody 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).

What are the symptoms of food allergy?

Normally food allergy symptoms appear within a few minutes of eating the offending food, although they may be delayed by up to a couple of hours. The symptoms are usually those of ‘classic’ allergy, some of which are listed here:

Gut reactions

Abdominal pain



Skin reactions:


Swelling (rash or nettle rash)

Respiratory reactions

Runny nose




How do you set your food allergies?

Your food allergen settings are accessible through the profile carousel at any time! 

When you’re met with the profile settings carousel, simply tap the no entry sign icon for allergens, where you’ll see a screen of ingredients beside toggles. We ask you to toggle all the food allergies that you have, click save, and then complete the next step of your profile set up!

Once you have selected these, they are used by the app in EVERY product scan or menu browse that you do.

How will you know if there’s an allergen in the selected food?

If a meal or product contains an ingredient you’ve listed in your allergens, you’ll see a red no entry sign. But please take our advice on this; once you’ve correctly set your allergens, for your own safe-eating, it’s definitely best to leave them.
