How To Protect Your Child From Their Peanut Allergies

A peanut allergy is when your child’s immune system reacts to a normally harmless protein in peanuts. Allergic reactions can be mild such as skin welts, tingling mouth and stomach symptoms. However, some can be life-threatening (anaphylaxis). 1, 2

Peanut allergy has increased in children during the past few decades. The current rate is 3% of one-year olds. The reasons aren’t fully understood yet, but most likely it involves an interaction between genes and external factors. 2, 3

One of the external factors may actually be the increase in peanut-free diets that aim to protect children from allergy. Studies now show this may be having the opposite effect. 3, 4 It appears the older some children are the first time they eat peanuts, the less efficient their stomachs are at learning the difference between a harmless peanut protein and a harmful protein, such as a virus or bacteria. 5

What to do if your child has Peanut Allergies

* If your child has a known peanut allergy, definitely avoid peanuts and have emergency treatment ready in case of anaphylaxis. 2

* If your child is at high-risk of developing a peanut allergy (this may be defined as having a sibling or parent with a known allergy), 6 eating peanuts may help prevent an allergy developing. 4, 7, 8

Speak with a doctor before introducing peanuts to receive appropriate testing and advice. 7

* If your child isn’t at high-risk, after you start introducing other solid foods to your baby from around 6 months of age, you can also introduce peanuts. 4, 6, 9

Speak with a doctor before introducing peanuts, particularly if you’re uncertain about the risk.

* Advice on introducing peanuts may include: start with foods like peanut butter, not whole peanuts (which can cause choking); the first time should be at home; if your child has no allergic reaction, you may gradually increase the amount. 6
