Statistics
More than a quarter of a million Quebecers live with food allergies
- It is estimated that approximately 300,000 people in Quebec have food allergies, representing 4% of the province’s population. Health Canada’s estimates are even higher:
According to a recent publication [i], approximately 7% of Canadians self-report a food allergy. However, fewer are likely to have a physician-diagnosed food allergy, which are estimated at prevalence levels up to 5-6% for young children and 3-4% for adults in westernized countries [ii] [iii].
- 40,000 children in Quebec elementary schools have food allergies [iv].
- 7% of Quebec families have at least one allergic person (parents, family, friends, office colleagues, business partners, etc.) [v].
- The Ministère de la Santé et des Services sociaux du Québec estimates that 6% of babies, 3% of children aged 10 years and over, and approximately 1 to 2% of adults are affected by one or more food allergies. [vi]
Food allergies can be caused by a wide variety of foods
- Nine foods are responsible for more than 90% of allergic reactions: cow’s milk, eggs, soy, wheat, peanuts, nuts (walnut, hazelnut, almond, cashew, pecan and pistachio), mustard, fish and seafood [vii].
- In Canada, more than 160 foods have been identified as triggers for allergic reactions [viii].
The majority of children outgrow their allergies before the age of 7
- 76% of milk allergies are outgrown before the age of 5 [ix].
- 75% of egg allergies are outgrown before the age of 7 [x].
- 80% of wheat allergies are outgrown before the age of 5 [xi].
- Only 20% of peanut allergies are outgrown before the age of 7 [xii].
