People who think they’re allergic to tree nuts such as walnuts or almonds may not really be, doctors reported Monday.
And people who are allergic to one nut may not necessarily be allergic to other types of nuts, the team of allergy experts found.
It may be worth getting tested by an allergist for each specific nut, the team reported in the Annals of Allergy, Asthma and Immunology.
“Too often, people are told they’re allergic to tree nuts based on a blood or skin prick test,” Dr. Christopher Couch of the University of Michigan Medical School , who led the study, said in a statement.
“They take the results at face value and stop eating all tree nuts when they might not actually be allergic.”
Couch and colleagues looked at the medical records of 109 people with known tree nut allergies who got tested for allergies to other nuts.
