Soy allergy is one of the more common allergies in North America, and is on the priority allergen list for both Canada and the United States. However, it’s unclear exactly how many people suffer from the allergy.
Peanuts are the most common legume that people will react to, and about 5 per cent of peanut allergic people will react to other legumes, such as beans, peas chickpeas and lentil.
In general, food allergy 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.
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.
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.
