IgE mediated food allergies are a specific immune reaction to food proteins that results in the production of the antibody immunoglobulin E (also known as IgE) being produced. This creates a series of reactions and symptoms which can all trigger an anaphylactic response – which is a dangerous whole body allergic reaction.
IgE Mediated Symptoms may include the following:
What are the symptoms?
- Itching skin and eyes
- Nausea, vomiting and diarrhea
- Congestion and coughing
- Asthma symptoms: difficulty breathing and wheezing

- Often used in battered/fried foods, pastries, and as an ingredient for its binding properties in other processed foods.
If my child is allergic to eggs from a chicken, will they be allergic to other kinds of eggs?
Eggs sourced from a chicken have similar proteins to those found in other kinds of bird eggs that are commonly consumed such as ducks, quails, and geese. For these reasons, if there is an allergy present for eggs from chickens, reactions may occur for other eggs as well!
In some cases, individuals can consume eggs that have been highly heat processed such as being incorporated into a cake, however it is important to consult an allergist prior to making any assumptions.
Can be found in:
- it can also can be a component of baked goods, glazes, soups, and sauces.
What is the cause?
Allergic reactions to milk are associated with the protein found in cow’s milk. This protein is similar to those found in other milks such as goats and sheep milk. Often a similar reaction is likely to occur for other mammals’ milk if an individual has an allergy to cow’s milk protein.

This is a hybrid grain that is formed by combining wheat and rye and can cause a reaction for those who experience wheat allergies.
Wheat allergies are commonly found in infants and in these cases are usually outgrown, however adults wheat allergies are typically lifelong.
Are wheat allergies and celiac disease the same thing?
No! A wheat allergy and celiac disease are different conditions both having different kinds of reactions within the body.
- Wheat allergies are an immune reaction in which the body produces antibodies in response to the wheat protein which can ultimately be life threatening
- Celiac disease is a different immune reaction that damages the lining of the intestine which occurs from gluten, the specific protein found in wheat and other grains causing malabsorption
Where does sesame come from?
Sesame comes from a plant that contains seeds known as sesame. Other names for sesame include benne seed, gingelly, and sesamol.
Often found in breads such as bagels, other baked goods, cereals, dips, and spreads like hummus.
