According to a 2019 New York Times report, at least one million children and adults in the United States are allergic to sesame, an ingredient used in everything from soups to snack bars.
Dr. Ruchi Gupta, director of the Center for Food Allergy and Asthma Research at Northwestern’s Feinberg School of Medicine in Chicago, notes that sesame is in a lot of foods as hidden ingredients and is very hard to avoid. She considers it the ninth most common food allergen in the United States.
Gupta’s team’s research indicates that 4 in 5 people with sesame allergy have at least one other food allergy.
- More than half have a peanut allergy
- One in three have tree nut allergy
- One in four have egg allergy
- One in five have cow’s milk allergy
It is important to note that sesame labeling is not required by law as it is with eight common food allergens: egg, milk, peanut, tree nut, wheat, soy, shellfish, finfish, and the proteins derived from these foods.
Individuals with sesame allergy and parents of children with sesame allergy need to be diligent in determining which foods are safe to eat. Sensitivity to sesame varies from person to person, and reactions can be unpredictable.
A mild reaction once does not mean the individual will always have a mild reaction – the next reaction may be a life-threatening anaphylactic reaction. Individuals with sesame allergy are encouraged to keep an epinephrine auto-injector at all times as the first-line treatment for anaphylaxis.
Possible symptoms of a sesame allergy include:
- Abdomen pain
- Hoarse voice
- Itchiness in the throat or mouth
- Redness in the face
- Difficulty breathing
- Low pulse rate
- Life-threatening anaphylaxis
