Heartburn results from the upward flow of acidic liquid when the stomach valve malfunctions. To prevent it, it is recommended to reduce the size of meals, avoid fatty foods, foods high in protein, or carbonated beverages, and not lie down immediately after eating.

The influence of posture after a meal is well documented: a meta-analysis published in Nutrients (2024) confirms that lying down too soon promotes reflux, validating the benefit of waiting before going to bed. Similarly, observational studies support the idea that meals that are too large or high in fat slow down digestion and facilitate the opening of the gastric valve. Conversely, the impact of carbonated beverages is more nuanced: a systematic review indicates that there is no solid evidence demonstrating that they systematically worsen these sensations of discomfort. Regarding proteins such as red meat, science suggests an inverse effect, as proteins tend physiologically to stimulate the closing of this protective valve. Finally, the link to a bacterium is complex: a meta-analysis of randomized controlled trials published in the Turkish Journal of Gastroenterology shows that its elimination does not necessarily improve digestive comfort and can sometimes even accentuate reflux. Thus, rather than a blanket avoidance of all these foods, experts today encourage individuals to identify their own specific sensitivity factors.
