Although not a major cause, nuts, such as cashews, can trigger heartburn in some individuals.
- Nuts, including cashews, are high in fats, which slow down the emptying stomach.
- This means that they can cause a distended stomach, which can exert pressure on the lower esophageal sphincter or LES.
- The LES is a muscular ring-like structure present at the lower end of the esophagus at its junction with the stomach that prevents reflux of the acidic stomach contents into the esophagus.
When gastric emptying is slowed, as occurs with fatty foods, the acidic stomach contents can pass back into the esophagus causing heartburn. This may specifically be seen when consuming cashew and other fatty foods in excess.
Some people may have tree-nut allergies including cashew allergies. They may develop symptoms, such as nausea, vomiting, and indigestion when consuming cashews.

Heartburn vs. Acid Reflux (Differences and Similarities)
