What is food allergy?

It is a reaction by your immune system to a normal amount of a particular food. This reaction happens every time that food is eaten.

Although food allergies are rare, they are most common in children under the age of four.

The most frequent food allergies are to:

- milk

- eggs

- fish

- nuts

- citrus fruit

- tomatoes

What are the symptoms?

Children with food allergies often have several different symptoms. These include:

- severe infantile eczema or skin rash

- vomiting and diarrhea for no apparent reason

- asthmatic bronchitis or asthma

- allergic cold (itchy, streaming eyes and nose).

How do food allergies begin?

A hypersensitive reaction towards food is usually a type 1 allergic reaction to something in the diet. This means your child's immune system produces a class of antibodies called IgE in response to a particular food. These antibodies cause the allergic symptoms.

Almost one third of the population omit certain foods from their diet or their children's diet because they believe they cause an allergic reaction. In fact, only about 3 per cent of children suffer allergic reactions towards food, and most will outgrow them before they reach the age of three.

Who's at risk?

Type 1 allergic diseases are to some extent inherited. For this reason you may want to talk to your GP or allergy specialist before you get pregnant if there is a family history of allergy, hay fever, eczema or asthma.

What should I do if I suspect my child has a food allergy?

Contact your doctor first.

- Do not put your child on a strange restricted diet that could result in malnutrition.

- A change in your child's bowel movements is not a sign of food allergy.

- It is completely normal for a child's bowel movements to change if their diet is changed.

- Most importantly: relax. Don't assume that your child is suffering from a food allergy until this has been confirmed by an allergy specialist.

How are food allergies treated?

A diet that eliminates the food is the main treatment for this type of allergy.

In rare cases, eating even a small amount of the food can cause anaphylactic shock (severe difficulty breathing and heart malfunction), leading to collapse.

Anaphylactic shock needs immediate treatment with adrenaline, so seek medical help straight away if your child suddenly begins to have difficulty breathing.
