Why are food allergies in children on the rise – and is there anything parents can do to protect them?
Around 7% of children have food allergies and, as the recent case of Natasha Ednan-Laperouse showed, in rare, tragic instances, these can be fatal. How worried should parents be?
In July 2016, Natasha Ednan-Laperouse collapsed on a flight from London to Nice, suffering a fatal allergic reaction to a baguette bought from Pret a Manger. At an inquest, the court heard how Natasha, who was 15 and had multiple severe food allergies, had carefully checked the ingredients on the packet. Sesame seeds – which were in the bread dough, the family later found out – were not listed. “It was their fault,” her father Nadim said in a statement. “I was stunned that a big food company like Pret could mislabel a sandwich and this could cause my daughter to die.”
This horrifying case highlights how careful people with allergies need to be, as do the food companies – not least because allergies have been growing in prevalence in the past few decades.
“Food allergy is on the rise and has been for some time,” says Holly Shaw, nurse adviser for Allergy UK, a charity that supports people with allergies. Children are more likely to be affected – between 6 and 8% of children are thought to have food allergies, compared with less than 3% of adults – but numbers are growing in westernised countries, as well as places such as China.
“Certainly, as a charity, we’ve seen an increase in the number of calls we receive, from adults and parents of children with suspected or confirmed allergy,” says Shaw. Certain types of allergy are more common in childhood, such as cow’s milk or egg allergy but, she says: “It is possible at any point in life to develop an allergy to something previously tolerated.”
Stephen Till, professor of allergy at King’s College London and a consultant allergist at Guy’s and St Thomas’ hospital trust, says that an allergic reaction occurs when your immune system inappropriately recognises something foreign as a bug, and mounts an attack against it. “You make antibodies which stick to your immune cells,” he says, “and when you get re-exposed at a later time to the allergen, those antibodies are already there and they trigger the immune cells to react.”
