Summary of “Why the world is becoming more allergic to food”

Around the world, children are far more likely than ever before to develop food allergies.
Food allergy now affects about 7% of children in the UK and 9% of those in Australia, for example.
The frequency of food allergy has increased over the past 30 years, particularly in industrialised societies.
Australia has the highest rate of confirmed food allergy.
The increase in allergies is not simply the effect of society becoming more aware of them and better at diagnosing them.
A newer, “Dual allergen exposure” theory, suggests food allergy development is down to the balance between the timing, dose and form of exposure.
There is currently no cure for food allergy, and managing the condition relies on avoiding the offending foods and on an emergency treatment plan in case of exposure.
The main way to identify food allergies is for a patient to gradually eat increased amounts of that food under medical supervision.
