Facts about tree nut allergy

  • Tree nut allergy affects 1.6% of children under 18 years of age and 1.2% of adults in Canada[1].
  • Tree nuts include almonds, hazelnuts, Brazil nuts, cashews, walnuts, pistachios, pecans, macadamia nuts, pine nuts, and others.
  • Peanuts are not considered tree nuts. Rather, they are in the legume family. It is possible to be allergic to nuts without being allergic to peanuts. The opposite is also true.
  • A person with a tree nut allergy may react to only one type of nut, but may also react to several. In addition, a person allergic to one type of nut is at greater risk of developing an allergy to other nuts.
  • It should be noted that, even if allergic to one type of nut, the risk of contamination between the different nuts, as well as between nuts and peanuts, is very high.
  • Nutmeg: since it is not a nut, its consumption is safe for individuals allergic to nuts.
  • Coconut: it is part of the palm family and has only a distant relationship with nuts. It should be noted that coconut allergy is very rare, and concomitant coconut allergies are considered isolated cases [2].
  • Shea nuts: related to the Brazil nut, shea nuts are in the nut family. However, shea nuts and their butter, used in a large number of soaps, body creams, and cosmetics, have low amounts of protein compared to other types of nuts, which would reduce their allergenic potential [3]. Nevertheless, people with nut allergies should always be cautious about eating shea nuts or using shea butter.
  • A person allergic to one type of nut is at greater risk of having an allergy to other types of nuts [4].

Health Canada’s food allergen labelling regulations established in 2012 prohibit use of these terms. Manufacturers must declare the presence of nuts in the list of ingredients, either on the label of their product or in the words “Contains.” However, it is important to keep those 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 homemade or artisanal products.
