FODMAP is an acronym that describes 5 different sugars that are found in commonly consumed foods that include fermentable, oligosaccharides, disaccharides, monosaccharides and polyols 1.
Each of these sugars shares three major characteristics including poor absorption within the small intestine, rapid fermentation as a result of the length of the carbohydrate chains present in these sugars and a high level of osmotic activity due to the small size of these sugars.
These properties combined with the similar structure of these sugars play an important role in their ability to induce a number of gastrointestinal (GI) issues including bloating, gas, abdominal pain, nausea, diarrhea and/or constipation 2.
These symptoms are commonly found in people with GI issues such as small intestinal bacterial overgrowth (SIBO), irritable bowel syndrome (IBS) and other related disorders, which explains why a low-FODMAP diet has often been recommended and found success in helping alleviate some of the symptoms these individuals experience with their respective disorders.
In this article, we will break down everything you need to know about the Low-FODMAP diet. What exactly it is, how the FODMAP plan works, a Low-FODMAP diet food chart, list, and recipes so that you can find relief!

How Does a Low FODMAP Diet Work?
There are three phases of a low FODMAP diet plan:
- ELIMINATE → Completely remove all high FODMAP foods from your diet. The duration of this phase should be about 2-4 weeks.
- REINTRODUCE → Slowly add FODMAP foods back to your diet. The duration of this phase should be 6-8 weeks.
- MAINTENANCE → Work with your healthcare provider to decide which foods can be added back to your diet, depending upon what your results of phase 2 of the diet show.
By following these steps of the low FODMAP diet, individuals with SIBO, IBS or other GI disorders are able to normalize their daily food patterns to ensure that they receive an adequate supply of all nutrients.
Additionally, by reintroducing certain foods back into their diets, these individuals are better able to identify exactly which food items and groups are causing them to experience symptoms, and which they can tolerate with little to no problems.
Note: In the case of SIBO and IBS a lot of people stick to a FODMAP conscious diet for the long term because they find that the super high FODMAP foods really cause issues.
This does not mean you will have to restrict all higher FODMAPs forever but that you will figure out which highly fermentable carbohydrates you need to be careful with and limit.
It’s about learning what’s best for your own gut!
Importance of a Food Diary
It is strongly encouraged that when an individual begins the low FODMAP diet that they use a food diary to track their daily nutrition intake, as well as any environmental, emotional or physical factors that may influence the severity of their symptoms.
Using a food diary at the beginning of the diet is a good way to find out what exactly you are eating and how that affects your GI symptoms. Sometimes, unless you do a diary for a few weeks it’s hard to remember what exactly you ate.
Although, this does not mean you have to continue with a food diary ongoing since over time you will learn which foods are best for you.
For example, when you discover that certain foods cause you more gas, flatulence, or diarrhea, you can immediately record your symptoms so that you can limit and be careful with that carbohydrate in the future.
Does Research Support the Low FODMAP Diet?
The first clinical study that evaluated the potential clinical benefits of a low FODMAP diet was published in 2008, and a number of subsequent studies have demonstrated how the low FODMAP diet shows a therapeutic response in IBS patients in particular.
In fact, over the last 10 years, IBS patients have shown a 52-76% improvement in their symptoms with the low FODMAP diet, which has supported the widespread adoption of this dietary approach for GI issues.
To date, approximately 400 clinical studies have been performed to assess the efficacy of the low FODMAP diet on patients with a wide range of GI disorders including IBS, ulcerative colitis (HC), SIBO and Crohn’s disease (CD).
The following chart describes some of the clinical studies that have been performed to study the effect of the low FODMAP diet on patients with GI disorders.
|Bohn et al. (2015)||4 weeks||50% symptom improvement in patients with IBS.|
|Eswaran et al. (2017)||4 weeks||11% therapeutic gain in patients with IBS-D. More significant improvements in reducing pain, bloating and frequency of bowel movements were seen.|
|Staudacher et al. (2017)||4 weeks||Investigated the low FODMAP diet with or without probiotic supplementation. Researchers found that patients significantly improved on the low FODMAP diet as compared to a sham diet.|
What GI Disorders Respond Best To A Low FODMAP Diet?
Although most of the clinical studies have focused on the efficacy of the low FODMAP diet with treating the symptoms of IBS patients, patients with the following GI issues have also shown clinical improvement when adopting this diet to their daily life.
- Functional diarrhea (chronic loose stool without abdominal pain)
- Abdominal bloating
- Non-celiac gluten sensitivity
- Celiac disease
- SIBO (60% of IBS patients have SIBO)
