Which of the following foods is NOT commonly associated with oral allergy syndrome?

Oral allergy syndrome (OAS) is a condition that occurs when certain proteins in fruits and vegetables cause an allergic reaction, typically in individuals who are also allergic to pollen. This syndrome is characterized by symptoms such as itching or swelling in the mouth, throat, or lips after eating certain foods.

Potatoes are not commonly associated with OAS because they contain different types of proteins that are less likely to cross-react with pollen proteins. While potatoes are a commonly consumed food, they are generally considered safe for individuals with OAS, unlike the other options listed, which have proteins that can trigger reactions in susceptible individuals.

In contrast, bananas, tomatoes, and cherries are more frequently linked to OAS. These foods contain proteins that can mimic the structural properties of common pollen allergens, making them more likely to cause reactions in those with pollen allergies. Therefore, identifying potatoes as the food not commonly associated with OAS is accurate.
