Heartburn and Nuts-What is the Connection?

A report compiled by multiple scientific studies and medical authorities; nuts such as almonds and hazelnuts bring various health benefits thanks to the essential nutrients they contain.

Nuts adding their excellent taste to their health benefits appear to be an exceptionally smart and enjoyable way to snack. Still, there is research that says nuts are a potential heartburn trigger for acid reflux sufferers!

If you are still uncertain that nuts, which are associated with various health benefits, can trigger heartburn? Then it might shock you that although nuts are quite healthy, still they may also give you heartburn, especially if you eat too many of them at one go “.

What Is Heartburn?

Heartburn is commonly described as a burning discomfort below the breastbone. A bitter or acidic taste may also be noticeable in the back of your throat.

Acid reflux is a common cause of heartburn, according to the American Gastroenterological Association (AGA). When the band of muscle at the bottom of your esophagus, or food pipe, called a sphincter, fails to close correctly, stomach acid and food from your stomach flow back up toward your mouth. If you have heartburn more than a few times each week, you may have gastroesophageal reflux disease (GERD).

Can Eating Nuts Give You Heartburn?

When we talk about foods that cause heartburn, nuts don’t get much attention. Caffeine, spicy foods, and acidic fruits take the attention away from other culprits. Tree nuts are one of these lesser-known foods.

Tree nuts are fatty and oily, which are both characteristics that cause heartburn. Tree nuts may not seem like a particularly fatty snack, but according to the USDA, almonds have roughly 18 grams of fat every 14 cup serving. This high-fat content can cause the lower esophageal sphincter (LES) to relax, increasing acid reflux in patients who already have severe heartburn.


To help you choose, here’s how some popular types of nuts stack up, according to the U.S. Department of Agriculture, in terms of their fat content, described as the amount of fat in 1 ounce of the nuts, shelled:

  • Pistachios, 12.8 grams
  • Cashews, 13.4 grams
  • Peanuts, 13.9 grams
  • Almonds, 14 grams
  • Hazelnuts, 17 grams
  • Walnuts, 18.5 grams
  • Brazil nuts, 18.8 grams
  • Pecans, 20.2 grams

While almonds aren’t the lowest-fat nut on the list, they do have another property that may make them less likely to worsen reflux symptoms:

Why Nuts Trigger Heartburn?

High-fat content in nuts can end up in heartburn. And their fatty feature is not the only factor that increases the risk of acid reflux. There are other factors too:

2- Nuts May Loosen the Lower Esophageal Sphincter

The influence of nuts on the Lower Esophageal Sphincter (LES), a barrier-like muscle that stops stomach acid from escaping into the food pipe, is the second reason nuts are linked to heartburn.

3- Nuts Trigger the Release of the Cholecystokinin

The important thing to know about cholecystokinin is that this is a hormone mostly related to appetite and digestion.
