Can onions and celery be eaten together?

Generally speaking, onions and celery can be consumed together in moderate amounts. The detailed analysis is as follows:

Onions contain sulfides, vitamins, and dietary fiber, while celery is rich in vitamin K, calcium, potassium, and dietary fiber. Consuming these two foods together can provide complementary nutrition. In daily cooking, they can be stir-fried, served cold, or added to soups. Generally, people without specific health issues can consume them together in moderate amounts without experiencing adverse reactions. Additionally, this combination can supply antioxidants and various trace elements to the body.

For individuals with weak gastrointestinal function, the high fiber content of celery and the irritant compounds in onions might jointly irritate the digestive tract, potentially causing discomfort such as bloating and abdominal pain. These individuals should control their intake and avoid consuming them on an empty stomach. People allergic to allium plants (such as onions) or to umbelliferous vegetables (such as celery) might experience allergic reactions, such as skin itching and oral tingling, when consuming these foods together. Consumption should be stopped immediately, and the individual should monitor their physical condition.

When consuming onions and celery, it is recommended to adjust the cooking method according to digestive capacity. Celery can be blanched to soften its fibers, and onions can be cooked to reduce their pungency and irritation. Additionally, attention should be paid to the quantity consumed to avoid ingesting excessive fiber in a single meal.
