Is Olive Oil Low FODMAP? A Comprehensive Guide

People often praise olive oil for its health benefits as it is a popular and versatile cooking ingredient. However, for people with irritable bowel syndrome (IBS) who follow a low FODMAP diet, the question arises: is olive oil low FODMAP?

In this article, we will explore what FODMAPs are, why they are relevant for people with IBS, and whether olive oil is suitable for a low FODMAP diet.

What Are FODMAPs?

The small intestine finds it difficult to absorb a group of carbohydrates called FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols). These carbohydrates travel to the large intestine, where bacteria ferment them, resulting in symptoms such as bloating, gas, abdominal pain, and diarrhea in people with IBS.

Commonly consumed foods such as wheat, onion, garlic, beans, and milk are high in FODMAPs.


Why Is the Low FODMAP Diet Relevant for People with IBS?

The low FODMAP diet is a dietary approach that has been developed by Monash University in Melbourne, Australia, to help manage IBS symptoms. The diet involves restricting high FODMAP foods for a period of time and then gradually reintroducing them to identify which ones trigger symptoms. Studies have shown that the low FODMAP diet can be effective in reducing IBS symptoms in up to 75% of people with IBS.


Is Olive Oil Low FODMAP?

The answer is yes. According to Monash University’s FODMAP app, olive oil is low FODMAP in servings of up to 1 tablespoon (13 g).

However, larger servings (over 1 tablespoon) may contain moderate amounts of the FODMAP “polyols,” specifically mannitol, which could potentially trigger symptoms in some people with IBS.

It is important to note that the FODMAP content of olive oil can vary depending on the processing method, the type of olives used, and the storage conditions. Experts generally consider extra-virgin olive oil to be the highest quality and healthiest type of olive oil.

However, the presence of polyphenols, which are beneficial compounds found in olives, may result in extra-virgin olive oil containing more FODMAPs than refined olive oil. Similarly, if olive oil is stored for too long or exposed to light and heat, its FODMAP content may increase.


How to Use Olive Oil on a Low FODMAP Diet

If you are following a low FODMAP diet, you can safely use olive oil in small to moderate amounts. Here are some tips for using olive oil on a low FODMAP diet:

  • Stick to the recommended serving size of up to 1 tablespoon (13 g) per meal or snack.
  • Use refined olive oil instead of extra virgin olive oil if you are concerned about the FODMAP content.
  • Store olive oil in a cool, dark place, away from direct sunlight and heat.
  • Avoid using flavored or infused olive oils, which may contain high FODMAP ingredients like garlic or onion.


Using olive oil on a low FODMAP diet can have several benefits. Here are some reasons why you may want to incorporate olive oil into your low FODMAP diet:

  • The healthy fats in olive oil, including monounsaturated and polyunsaturated fats, are known to reduce inflammation, lower cholesterol levels, and improve heart health. Therefore, olive oil is considered a healthy source of fat.
  • Olive oil’s versatility makes it an ideal ingredient for low FODMAP meals, as it can be used in a variety of cooking methods like sautéing, roasting, and baking.
  • It adds flavor: Olive oil has a distinct flavor that can enhance the taste of your meals without adding high FODMAP ingredients like onion or garlic.


While olive oil is low FODMAP in small amounts, some people with IBS may still experience symptoms when consuming it. In this case, there are several alternatives to olive oil that can be used on a low FODMAP diet, including:

Coconut oil

The body can easily absorb coconut oil, which is a medium-chain triglyceride (MCT) oil, and it can offer a comparable taste and texture to olive oil when used in cooking.

Canola oil

Canola oil is a neutral-tasting oil that is low in saturated fat and high in monounsaturated fat, making it a healthy alternative to olive oil.

Grapeseed oil

Grapeseed oil is a light-tasting oil that is high in polyunsaturated fat and low in saturated fat, making it a healthy option for low-FODMAP cooking.

Can olive oil trigger IBS symptoms?

For most people, consuming olive oil in moderation is unlikely to trigger IBS symptoms. However, those with a sensitivity to the polyphenols found in olive oil may experience symptoms.

How much olive oil can I consume on a low FODMAP diet?

The recommended serving size of olive oil on a low FODMAP diet is up to 1 tablespoon per meal. This should be well-tolerated by most individuals.

Can I use this oil for cooking while following a low FODMAP diet?

Yes, you can cook with olive oil on a low FODMAP diet. However, be mindful of the cooking temperature, as high heat can degrade the quality of the oil.

Does light olive oil have the same health benefits as extra-virgin olive oil?

Light olive oil has fewer polyphenols than extra-virgin olive oil, so it may not provide the same health benefits. It is recommended to choose an extra-virgin olive oil for its higher nutrient content.

Is it possible to replace other cooking oils with an alternative on a diet that restricts certain types of carbohydrates?

Yes, you can use olive oil as a substitute for other cooking oils on a low FODMAP diet. It’s a healthy and versatile option for cooking and dressing salads.

Is consuming olive oil associated with any risks?

Consuming large amounts of olive oil, which is high in calories and fat, may lead to weight gain. However, it is generally considered safe for most people. Additionally, some individuals may be allergic to olive oil or have a sensitivity to its polyphenols. It’s important to consume olive oil in moderation and be aware of any potential allergies or sensitivities.

Final Thoughts

Olive oil is safe for low FODMAP diets in small to moderate amounts. Follow the recommended serving size and use refined oil. Proper storage minimizes the risk of increased FODMAP content.

Moreover, if needed, several alternatives to olive oil can be used on a low FODMAP diet. Incorporating healthy oils into your low FODMAP diet helps you enjoy nutritious and flavorful meals while managing IBS.
