The most comprehensive study ever into food allergies is about to be undertaken at a centre on the Isle of Wight.
The David Hide Centre in Newport is trying to find out why nut allergies are on the rise and how we can prevent them.
It follows several high profile cases in the media including the death of Natasha Ednan-Laperouse.
The 15-year-old went into cardiac arrest on-board a flight after eating a baguette from Pret a Manger at Heathrow Airport.
Thirty years ago doctors at the centre wanted to find out why children develop asthma, so they recruited 1,500 children in the oldest study in Europe.
They have tested for all kinds of allergens since.
The unique set of data collected shows that from the 1950s to the 1980s cases of asthma rose from 2% to 12% of the population.
But as asthma numbers stabilised, food allergies began to soar.
The Food Standards Agency is funding the latest study, in which 35,000 volunteers will take part.
It offers a unique opportunity to see how food allergies develop into adulthood from childhood.
If the food allergy goes away, doctors hope to find out why.
