Mythbuster series: Which allergens cause life-threatening reactions?

Mythbuster: Can only the top priority allergens (like peanuts, treenuts, milk, sesame, and soy for example) cause life-threatening reactions?

No. While it’s true that the top priority food allergens in Canada are responsible for triggering most food-induced allergic reactions, in fact, any food can trigger an allergic reaction.

For example, it’s possible to be allergic to certain fruits and vegetables, or to spices such as garlic and cinnamon. In other words, when it comes to food allergies, it’s important to never assume that only one of the top allergens can trigger a reaction.

As always, when in doubt about what you or someone you care about is allergic to, seek the expertise of an allergist.
