Q:  My son is allergic to sunflower seeds. Without having tried it, would he be also allergic to sunflower oil? 

A: As you know, people who are allergic to one seed may not be allergic to all seeds. Sesame is the most common seed allergy in the U.S., and most allergists recommend avoiding sesame oil, which is often unrefined. Sunflower is likely the most second most common seed allergy in the U.S. Not much is known about sunflower allergy.

Highly refined sunflower oil would not likely cause an adverse reaction in those with a sunflower allergy. But less refined or unrefined oils that contain the sunflower protein could possibly cause allergic reactions. Cold or expeller pressed oils are typically unrefined. Refined oils use a high heat process which can help remove food proteins from the oil and are unlikely to cause food allergy. I advise my patients to use caution since both oils exist.
