While they provide many health advantages, onions may also cause discomfort for some people, especially when consumed in large amounts.

Can Eating Onions Cause Problems?
For the majority of people, onions are safe and healthy. However, certain individuals may experience negative effects depending on how much and how often they eat them.
1. Digestive Discomfort
Eating a large quantity of onions, particularly raw ones, may lead to:
-
Abdominal bloating
-
Gas
-
Stomach pain
-
Acid reflux or heartburn
This happens because onions contain fructans, a type of carbohydrate that can be difficult to digest for some people. These compounds ferment in the gut and may trigger symptoms, especially in individuals with sensitive digestion or irritable bowel issues.
