Prevalence of Peanut Allergy
Peanut allergies are one of the most common food allergies in children and are on the rise.
A major study in the United States recently found that cases of peanut allergy in children more than tripled in a decade, and that more than 3 million Americans now have a peanut or nut allergy.
In Canada, recent research has shown 1.68 per cent of children have peanut allergy. In the United States, 1.4 per cent have peanut allergy. The rates are lower in adults in both countries.
In fact, food allergy in general is on the rise in North America and other developed countries. In Canada, an estimated 7.5 per cent of people have food allergies, representing more than 2.5 million people. In the United States it’s estimated that 12 million Americans (or just under 4 per cent of the population) have food allergies.
Here are the rates of some of the major allergens in Canada and the U.S.
|Peanut||1.68 %||0.71 %||0.93 %|
|Tree Nut||1.59 %||1 %||1.14 %|
|Shellfish||0.5 %||1.69 %||1.42 %|
|Fish||0.18 %||0.56 %||0.48 %|
|Sesame||0.23 %||0.05 %||0.09 %|

Milk and egg allergy are both common in children. In the United States, 2.5 per cent of children under the age of 3 have a milk allergy. Egg allergy affects 1.5 to 3.2 per cent of children.
The good news is many children outgrow their allergies to milk and egg.
