Introduction
Those with mild stomach issues, such as occasional bloating or indigestion, may benefit from适量 consuming well-cooked, tender onions. Onions contain dietary fiber that promotes intestinal motility and improves digestion, and they are also rich in vitamins and minerals that provide essential nutrients to the body. When prepared by steaming, boiling, or stewing, the pungency of onions is significantly reduced.

Whether individuals with poor stomach health can eat onions depends on specific circumstances. Those with mild symptoms and relatively normal digestive function may consume onions in moderation, while those with severe stomach diseases or during active disease phases should avoid them. Detailed analysis is as follows:

For individuals with minor stomach discomfort, such as occasional bloating or indigestion, moderate consumption of well-cooked, softened onions may be beneficial. Onions contain dietary fiber that helps promote intestinal motility and improve digestion, and they are rich in vitamins and minerals that help replenish nutrients. Once steamed, boiled, or stewed, the irritant properties of onions are significantly reduced, and small amounts generally do not impose a significant burden on the stomach.

However, onions are unsuitable for individuals with gastric ulcers, acute gastritis, gastroesophageal reflux disease, or severe stomach bloating and pain. The irritating components and spicy substances in onions can stimulate the gastric mucosa, exacerbate inflammation, and lead to intensified pain and acid reflux. Additionally, the sulfides in onions produce gas during intestinal breakdown, worsening bloating and impairing gastric recovery.

Individuals with poor stomach health should thoroughly assess their gastric condition before consuming onions. It is advisable to choose thoroughly cooked and finely chopped onions, strictly control portion sizes, and discontinue use immediately if gastrointestinal discomfort occurs after consumption, seeking medical advice promptly.
