Facts about peanut allergy

  • Contrary to popular belief, peanuts are not nuts, but legumes.
  • Peanut allergy is estimated to affect 2.4% of children and 0.7% of adults[ii].
  • It is estimated that 20% of children allergic to peanuts will outgrow their allergy with time [iii]. Unfortunately, there is a risk of recurrence of the outgrown allergy, when the food is not included regularly in the diet. This should be discussed with an allergist [iv].
  • People with peanut allergies usually tolerate other legumes such as peas, lentils, and beans.
  • It is estimated that 25% to 40% of individuals allergic to peanuts are also allergic to tree nuts[v]. These are considered two separate allergies.
  • By 2016, 17 allergenic proteins capable of inducing an allergic reaction had been identified in peanuts [vi]. A person with peanut allergy may react to one or more of these proteins.
  • Except for vegetarians and vegans, a single allergy to peanuts does not present a risk of nutritional deficiency. However, when multiple allergies are present, consultation with a nutritionist is important. The nutritionist can work to ensure a healthy, balanced diet despite multiple restrictions.

Health Canada’s food allergen labelling regulations established in 2012 prohibit use of the these terms. Manufacturers must clearly indicate the presence of peanuts in their product using the words “Contains” or “May contain.” However, it is important to keep these terms in mind when travelling, as regulations vary from one country to another. In some cases, it may also be useful to know them when we are offered artisanal products.
