Living with a Tree Nut Allergy
An estimated 1.8 million Americans have an allergy to tree nuts. Allergic reactions to tree nuts are among the leading causes of fatal and near-fatal reactions to foods. Tree nuts include, but are not limited to, walnut, almond, hazelnut, coconut, cashew, pistachio, and Brazil nuts. These are not to be confused or grouped together with peanuts, which are a legume, or seeds, such as sunflower or sesame.
Like those with peanut allergies, most individuals who are diagnosed with an allergy to tree nuts tend to have a lifelong allergy.

Breading for chicken
Mandelonas (peanuts soaked in almond flavoring)

Keep in Mind
Many experts advise patients allergic to tree nuts to avoid peanuts and other tree nuts because of the high likelihood of cross-contact at processing facilities, which process peanuts and different tree nuts on the same equipment. Further, a person with an allergy to one type of tree nut has a higher chance of being allergic to other types.
Tree nuts may be found in a wide range of unexpected foods for flavor or consistency. If ingredient information is not provided for a particular food or you question its accuracy, avoid the food completely.
Younger siblings of children allergic to tree nuts may be at increased risk for allergy to tree nuts.
Tree nuts can cause severe allergic reactions. Always carry epinephrine is your doctor prescribes it.
