What is a food \ supervised feed?
A food challenge is always performed in hospital as it is the safest way of finding out if your child reacts to a food or not.
How is a challenge performed?
You and your child will be admitted to the children’s clinic. The nurse who looks after your child will challenge a food in increasing doses until a top dose is successfully eaten/ swallowed.
If your child is having a food challenge, the food will be given in increasing doses every twenty minutes. Your child will be checked for signs of an allergic reaction prior to each dose of food being administered.
If your child is having a supervised feed, they will be given a normal portion of the food to eat within 30 mins and then monitored.
Once all the doses have been eaten you will need to stay on the ward for a minimum of 1 to 2 hours to ensure there is no delayed reaction to the challenge.
If there is no reaction within that time your child is no longer allergic.
You will be given further information on the day about introducing this into your child’s diet.
It is a long day, so please come prepared. We have a play area however you may wish to bring toys / activities to keep your child (and yourself!) entertained.
If your child is having a food challenge, we will provide the food being challenged however we will contact you in advance if we are unable to supply.
It is a good idea to bring foods your child likes which we could use to disguise the food should they not like the food being challenged (A list of the foods used for challenge are below).
Bribery treats are always useful if we are having difficulties, or your child is a fussy eater!
If you think your child may have difficulties with eating the food being tested, you can contact our allergy nurse specialist in advance to discuss ideas.

Meals for your child
Unfortunately, due to the vast range of multiple allergies we encounter we are unable to provide your child with a meal. Therefore, we ask that you bring a packed lunch / meal or snacks for your child. Unfortunately, there is no microwave on the unit. Please ensure that your child has eaten this food before, and it does not contain any of the food being challenged or they are allergic to.
Allergic reactions
Food challenges can cause an allergic reaction, involving the eyes, nose, mouth, skin, and gut. Anaphylaxis is a more severe form of these symptoms and can involve the airway, breathing and/or circulation.
Your child will constantly be assessed throughout the challenge and any symptoms will be monitored and treated as necessary. Anaphylaxis is very unusual during a food challenge but should this occur our team are experienced in coping with such situations.
After the challenge
If your child has reacted to the food during the challenge, he or she should not do strenuous play, activities, or exercise for the rest of the day as this could bring on a delayed reaction. A delayed reaction can happen up to 48 hours later.
If your child has not reacted to the food during the challenge, he or she should not eat the food until the following day in case of delayed symptoms. It is important to introduce the food into your child’s diet at regular intervals once they have passed the food challenge.
