The story starts with a startling situation in Britain, repeated in almost every other advanced country in the world. According to a recent study by Imperial College, London, the rate of food allergies in Britain doubled between 2008 and 2018. The UK Food Standards Agency now estimates that 6% of the British population has a clinically confirmed food allergy.
This may be an underestimate because over 30% of the UK population reported diverse adverse reactions to different kinds of foods, but only 6% or so were able to be confirmed as definite allergies by clinical assessments of various known allergen triggers.
