Aside from onions, there are a few other foods that may cause tears due to their pungency or irritants they contain:
Garlic: Similar to onions, garlic contains sulfur compounds that can cause tears when chopped or minced.
Hot peppers: Capsaicin, the compound responsible for the heat in chili peppers, can cause tearing and eye irritation when consumed or handled.
Horseradish: Grating or processing horseradish can release volatile compounds that may irritate your eyes and induce tears.
Wasabi: Wasabi, a popular condiment in Japanese cuisine, contains allyl isothiocyanate, which can stimulate your tear ducts and cause tearing.
Mustard: The volatile oils present in mustard seeds can lead to tears when they are crushed or processed.
Certain spices: Strong spices such as cayenne pepper, black pepper, and cinnamon can sometimes cause mild eye irritation and tearing.
It's worth noting that the extent of eye irritation and tearing varies from person to person, so not everyone may have the same reaction to these foods.
