After a meal, a burning sensation rises in the chest, an acid taste invades the mouth or the throat stings… For many people, these symptoms have become almost commonplace. However, certain foods consumed on a daily basis could well maintain this vicious circle. Good news: identifying them often allows you to find real digestive comfort.
Why do certain foods trigger heartburn?
Heartburn is the most common symptom of gastroesophageal reflux disease (GERD). They occur when acidic stomach contents flow up into the esophagus, causing that characteristic burning sensation behind the breastbone.
In France, it is estimated that around one in ten adults suffer from heartburn at least once a week, while several million people experience it almost every day, especially over the age of 50.
If stress, being overweight, pregnancy, a hiatal hernia or certain medications can promote this reflux, the contents of your plate also play a major role.
Indeed, certain foods relax the sphincter which normally prevents acid reflux, others slow down digestion or directly irritate the esophagus.
The 9 Foods That Most Often Make Heartburn Worse
They do not necessarily cause symptoms in everyone, but they are the ones that appear most often in scientific studies and in the recommendations of gastroenterologists.
1. Very fatty foods and fried foods
Fries, burgers, pizzas, nuggets or very rich dishes slow down the emptying of the stomach. Result: the stomach stays full longer, increasing the risk of acid reflux.
2. Chocolate
Bad news for gourmands: chocolate contains theobromine and a little caffeine, two substances capable of relaxing the sphincter located between the stomach and the esophagus.
3. Very spicy dishes
Chili pepper, harissa, hot sauces or certain curries can accentuate the burning sensation, especially in people already prone to reflux.
4. Citrus fruits
Orange, lemon, grapefruit or their juices are naturally very acidic. In some people, they directly irritate the esophagus, especially when consumed on an empty stomach.
5. Tomatoes
Tomato sauce, ketchup, fresh tomatoes or tomato paste combine natural acidity and irritating potential for people suffering from reflux.
6. Raw onions and garlic
They’re not a problem for everyone, but are among the foods most commonly reported as heartburn triggers.
7. Coffee
Even decaffeinated in some people, coffee can stimulate stomach acid production and promote reflux.
8. Mint
Surprising, but very real: mint, often consumed after meals to facilitate digestion, can on the contrary promote reflux in certain people by relaxing the esophageal sphincter.
9. Alcohol
Wine, beer, cocktails or spirits irritate the digestive mucosa while promoting acid reflux.
Not everyone reacts the same way
In reality, there is no “forbidden” food that is valid for everyone. Some people tolerate chocolate perfectly but react strongly to tomatoes. Others can drink coffee without problem but develop burns after a spicy meal.
This variability is also confirmed by studies.
On the other hand, several studies show that identifying and then avoiding trigger foods can really improve symptoms. A study reported by Presshealth notably observed that after just two weeks of avoiding the responsible foods, the proportion of people suffering from burns had fallen from 93% to 44%.
How do you know which foods are responsible in your home?
The most effective method is often the simplest.
For two weeks, write down in a notebook:
- What you eat;
- Meal times;
- The possible appearance of burning, regurgitation or an acidic taste.
Then try removing a suspect food for several days before gradually reintroducing it.
This approach often makes it possible to quickly identify the real culprits without eliminating many foods unnecessarily.
Habits matter as much as diet
Foods aren’t the only thing that can cause acid reflux.
Certain habits also increase the risk:
- Eat a very hearty dinner;
- Lie down within two or three hours after the meal;
- Wear clothing that is very tight around the abdomen;
- Eat meals quickly.
Conversely, eating a lighter dinner, allowing at least three hours to pass before bed, and slightly raising the head of the bed often help reduce symptoms.
Finally, if the burns become almost daily, accompanied by chest pain, difficulty swallowing or unexplained weight loss, it is important to consult a doctor quickly. Poorly managed reflux can sometimes lead to complications and therefore merits medical attention.
