Many people suffer from food allergies. More people today have a reaction to eating nuts more than ever before. Some children, in particular, cannot eat peanut butter and jelly sandwiches or even be in the same room as anything made with or made from peanuts or peanut butter. But the question remains, if you are allergic to one nut does that mean you are allergic to all nuts?


What are tree nuts?

Tree nuts are just one category where people find themselves having a reaction. What nuts constitute tree nuts? There are eight nuts in the tree nuts category: cashews, Brazil nuts, pecans, walnuts, pistachios, almonds, hazelnuts and macadamia nuts. If you are allergic to one of the nuts in this category, you should have an oral food challenge test to see if you are allergic to other nuts in this field as well.

You will be given a small amount of another nut to see if you have a reaction to it. Many researchers found that about 76 percent of the people who were tested for other nuts were able to pass this test and had no allergies to other nuts. There are blood tests and skin tests to determine allergies, but the food challenge is the most accurate way to confirm an allergy.

Some types of tree nuts are more alike than not so they have been known to “cross-react.” This group includes walnuts and pecans, pistachios and cashews, and hazelnuts and almonds. What this means is that if you are allergic to cashews you may find you have a reaction to pistachios, but not to hazelnuts or almonds.
