Tree nut allergy is in its own category in the top 8 most common food allergens It is not grouped together with peanut allergy as you might think. This is because tree nuts and peanuts grow differently and have different proteins that cause allergic reactions. Because of this, many people with a tree nut allergy can tolerate peanuts and vice versa. Also, it is possible to only be allergic to one type of tree nut, such as walnuts, and be able to tolerate other tree nuts, like almonds, just fine.
What makes managing peanut and tree nut allergies tricky? Well, a couple of things. First, peanuts and tree nuts are often produced and packaged in the same facilities on the same production lines. This means that the risk for cross-contamination is high. Second, peanut and tree nut allergies are usually not mild and often cause serious reactions.
In my experience, the most difficult part of managing these allergies in particular is preventing cross-contamination. From avoiding foods produced near peanuts and tree nuts to family gatherings at which nuts are present, managing a nut allergy can be a challenge.
