Research suggests that introducing common food allergens, particularly nuts, can help reduce the risk of a child developing a food allergy. BUT when you are a parent of a baby just starting out on solids, it’s often the last thing you want to do, isn’t it? We want to play it safe. Choking is a worry and adding in the risk of an allergic reaction doesn’t sound like the best thing to do! It’s so hard being a parent!
It’s a bit like crossing a road. It carries risk but it needs to be done in order to live life. You are aware it carries a risk; that’s why you look before you cross the road. You are aware of the rules of the road and you process the risk.
Well with allergens, the ‘rules’ we need to be aware of are the list of allergens and the signs that your baby is having an allergic reaction. These are our ‘looking as you cross the road’ as well as knowing ways to introduce those allergens.
What are the common food allergens?
The 14 common food allergens according to food.gov.uk (you will see them marked in bold on the ingredients list of foods) are:
- cereals containing gluten (such as barley and oats),
- crustaceans (such as prawns, crabs and lobsters),
- molluscs (such as mussels and oysters),
- sulphur dioxide and sulphites (above a certain amount) and,
- tree nuts (such as almonds, hazelnuts, walnuts, Brazil nuts, cashews, pecans, pistachios and macadamia nuts).
What are the signs your baby might be having an allergic reaction?
According to the NHS, signs develop within a few minutes of eating the food and they are:
- a runny or blocked nose
- red, itchy, watery eyes
- wheezing and coughing
- a red, itchy rash
- worsening of asthma or eczema symptoms
- and less commonly; a severe reaction called anaphylaxis or anaphylactic shock can occur – in which case you should call 999.
Symptoms of anaphylaxis according to the NHS include:
- feeling faint,
- difficulty breathing,
- raised heartrate,
- clammy skin
- as well as hives, feeling sick, swelling and stomach pain.
My child’s skin goes red after eating tomatoes, is that an allergy?
Whilst I can’t say yes or no, as they need to be assessed by a health professional, acidic foods, like tomatoes, can cause a reddening of the skin around the mouth so it’s not always a sign of an allergy.
I’ve made you want to avoid allergens at all costs now, haven’t I? Well, the risk of your baby having a reaction is low. It’s really important to try and introduce these foods early on. If you are feeling nervous, choose a time of day when someone else is around to introduce the food.
There are products which allow you to introduce allergens all at once to your baby but I recommend introducing them one at a time. It is much cheaper to buy real food than specialist products but it is also easier to tell which food they have reacted to if you introduce them separately.
Ideas of how to introduce allergens
Put a little peanut butter on your finger and let them suck your finger
Add a little cow’s milk to their baby cereal or mashed fruit
Add a little ground nut to their cereal or a sauce
Give a small piece of fish with their meal
Once you have introduced cow’s milk and are happy they aren’t reacting, make scrambled egg
Try a little homous (with Tahini – sesame paste)
Add a little bit of mustard to a cheese sauce (once you are happy with the cow’s milk)
Try some pasta or bread.
An extra safety note – foods to avoid
Children under 5 should not have whole nuts as they are a choking hazard – offer ground nuts, nut butters or, once weaning is established, pieces of nut instead.
Use eggs are ‘Lion’ eggs or ‘Laid in Britain’ eggs, if they aren’t make sure they are fully cooked (i.e. no runny egg!).
Thoroughly cook fish and shellfish. Children under 5 should avoid raw fish and shellfish due to the higher risk of food poisoning.
What to do if you think your baby is allergic to a food?
If they have an anaphylactic shock, call 999 immediately.
For other reactions speak to your GP or call 111.
If there is a history of food allergies in your family, please speak to your health visitor or GP for further advice. There is also a helpful factsheet on the British Society for Allergy & Clinical Immunology (BSACI) website.
Is is important not to take out foods from your baby’s diet without guidance as you can end up missing vital nutrients. Get support from a dietitian or Registered Nutritionist.
