30 Foods That Cause Acid Reflux
Tomatoes
Tomatoes are incredibly acidic, even if they aren't cooked. A raw tomato can cause just as much trouble as one prepared in a sauce or grilled. It's best to stay away from this food altogether. It can trigger reflux and worsen symptoms of gastroesophageal reflux (GERD).
One study in BMC Gastroenterol found that tomatoes even caused acid reflux when the pH was balanced out. Further studies are needed, but this could mean there's another reason tomatoes cause acid reflux.
