Can Coconut Oil Cause Acid Reflux?

What Is Acid Reflux?

Acid reflux, also called gastroesophageal reflux or acid indigestion, occurs when your stomach contents flow back up into your esophagus (the muscular tube connecting your mouth and stomach), according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). When acid reflux is chronic, it's called gastroesophageal reflux disease (GERD).

Two key muscles, your lower esophageal sphincter (the muscular valve between your esophagus and stomach) and diaphragm, typically prevent your stomach contents from flowing back up, according to the NIDDK. GERD can develop if your lower esophageal sphincter becomes weak or relaxes when it shouldn't. This might be more likely to happen if you:

  • Have overweight or obesity
  • Are pregnant
  • Smoke or inhale secondhand smoke

Certain medications can contribute to GERD, too. A hiatal hernia, a condition in which part of your stomach slides up through the diaphragm, can also play a part in GERD or make your symptoms worse.

Fats and Acid Reflux

What you eat and drink can trigger your GERD symptoms, and fat is a common culprit. Fats can cause acid reflux for two reasons, says Emily Haller, RDN, a registered dietitian nutritionist at the University of Michigan in Ann Arbor.

Some fats are worse than others for GERD, especially saturated and trans fats. Avoiding these may help ease or reduce reflux symptoms, according to the International Foundation for Gastrointestinal Disorders (IFFGD).

Coconut Oil May Trigger Acid Reflux

Coconut oil in particular may be a reflux trigger for some because it's high in fat, Haller says. In fact, coconut oil is 100 percent fat, the majority of which is saturated fat, according to the Harvard T.H. Chan School of Public Health.

While fats like coconut oil can make acid reflux worse, Haller stresses that GERD management depends on the individual. You don't need to avoid everything listed as a potential reflux-inducing food, she says. When it comes to your acid reflux, many different factors may play a role in improving your symptoms.

There's no proven "GERD diet," according to the IFFGD, so keeping track of your own triggers is key in managing your reflux. Often, just a few small changes in your diet can lead to improvement in your GERD symptoms.

Prevent Reflux By Avoiding Your Triggers

So, should you stop cooking with coconut oil? Maybe. It depends on your unique reflux triggers. But there are other ways to take control of your reflux. For her patients, Haller recommends:

  • Eating smaller and more frequent meals
  • Avoiding large meals before bedtime
  • Keeping track of which foods are specific triggers
  • Lying on the left side during sleep

In addition to these measures, Michigan Medicine suggests making changes such as elevating the head of your bed 6 to 8 inches, stopping smoking and losing excess weight.
