In patients with allergic rhinitis and nasal symptoms only, is there any value in recommending that they avoid cross-reacting raw fruits or vegetables to minimize their nasal symptoms? There are local ENTs in my area who recommend that their allergy patients follow a specific diet eliminating cross-reacting foods even if they experience no classic symptoms of oral allergy syndrome. Is there any scientific basis for this?


Thank you for your inquiry.

I am not aware of any evidence to substantiate the hypothesis that avoidance of cross-reacting fruit and vegetables will improve symptoms of rhinitis. I could find no such evidence with a literature search of the subject.

Thank you again for your inquiry.
