“Eating spicy food causes stomach ulcers.”

For generations, many have held the belief that consuming spicy dishes leads to the development of stomach ulcers. This widespread idea likely originated from historical observations and a lack of scientific understanding, where discomfort after eating hot foods was mistakenly linked to their direct causation of sores. Before the actual causes were identified, it was a common assumption in traditional societies that spicy ingredients could physically "burn" the stomach lining, thereby creating painful ulcers.

However, modern medical science has thoroughly debunked this long-held notion. Stomach ulcers are not caused by spicy food. The primary culprits behind these open sores on the stomach lining are a bacterial infection, specifically by Helicobacter pylori (H. pylori), and the long-term or excessive use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin. The pivotal discovery of H. pylori in the 1980s revolutionized our understanding, proving that these bacteria weaken the stomach's protective mucus layer, making it vulnerable to digestive acids.

The misconception likely persists because while spicy foods do not cause ulcers, they can certainly irritate an existing ulcer or trigger temporary symptoms such as heartburn, indigestion, or stomach pain in sensitive individuals. This immediate discomfort is often misinterpreted as the food causing the ulcer, rather than simply aggravating a pre-existing condition. Interestingly, some research even suggests that capsaicin, the compound responsible for the heat in chili peppers, may actually offer protective benefits to the stomach lining, further highlighting that spicy foods are not the root cause of ulcers.
