The symptoms of a food allergy almost always develop a bouche food seconds or minutes after eating the food. The most common type of allergic reaction to food is known as an IgE-mediated food allergy. Without quick treatment, it can be life threatening. If you think you or someone you know is experiencing anaphylaxis, dial 999 and ask for an ambulance as soon as possible.

Non-IgE-mediated food allergy Another type of allergic reaction is a non-IgE-mediated food allergy. Other symptoms can be much less obvious and are sometimes thought of as being caused by something other than an allergy. Mixed reaction Some children can have a mixed reaction where they experience both IgE symptoms, such as swelling, and non-IgE symptoms, such as constipation. This can happen to children who have a milk allergy. Exercise-induced food allergy In some cases, a food allergy can be triggered after eating a certain food and then exercising. This can lead to anaphylaxis in severe cases, sometimes known as food-dependent exercise-induced anaphylaxis.

This article is about the hors d’oeuvre. The name comes from the French word for sofa, drawing on the analogy that the garnish sits atop the bread as people do on a couch. Because they are often served during cocktail hours, it is often desired that a canapé be either salty or spicy, in order to encourage guests to drink more. A canapé may also be referred to as finger food, although not all finger foods are canapés.
