The number of children admitted to an English hospital with a severe allergic reaction has risen annually over the last five years.
According to NHS, 2018-19 1746 children were treated for anaphylactic shock in 2013-14.
Natasha Ednan-Laperouse's parents, who died of sesame in 2016 after eating a baguette, called the increase "deeply alarming".
Scientists say environmental factors may be responsible for more allergies.
In adults, hospital-treated severe allergic reactions were also included, with numbers increasing from 4,107 to 5,497 over a five-year period.
Children under the age of 10 were most likely affected by anaphylaxis, and 1,018 were admitted to hospital last year – compared to 601 in 2013-14.
Anaphylaxis is a serious allergic reaction that can be life-threatening.
The most common causes of severe allergic reactions are foods such as nuts, fish and shellfish, but they can also be triggered by wasp and bee stings, medicines and dairy products.
Even the slightest exposure to any of these allergens can be enough to trigger an anaphylactic reaction and trigger respiratory distress, rapid heartbeat, and unconsciousness.
It is not believed that the increase in allergies is due to society becoming aware of it and better diagnosing it. Instead, scientists believe that factors such as dietary change, microbial exposure and pollution could play a role in the rise – especially for Western lifestyles.
