A low FODMAP diet can serve as the foundation of a successful IBS diet. Here we explain how a low FODMAP approach works, what foods fit within its purview, and some quick tips and meals to get on track!
Scientific studies have shown that some short-chain carbohydrates are not well-digested in the small intestine and can induce abdominal symptoms that look a lot like IBS. Scientists hypothesized that eliminating these carbs from your diet may alleviate IBS symptoms. FODMAPS include six types of short-chain carbs, with each letter representing a different carbohydrate form.
The best part of the low FODMAP approach to an IBS diet is that it can include all food groups. There are fruits, vegetables, grains, and other diverse food types that fall within the low FODMAP philosophy.
|FODMAP containing carbohydrates||Examples|
It is found in cow, sheep and goat’s milk. Researchers first discovered the linkage between lactose and GI issues in 1959. However, it took another six years before the linkage to malnutrition was fully understood.
Naturally occurring sugar found in fruit and honey. Fructose could also be added into foods in the form of high-fructose corn syrup (HFCS) and agave syrup. A novel test in 1983 demonstrated the link between fructose mal-absorption and diarrhea. Subsequent studies showed the added effectiveness of adding a further sorbitol restriction to fructose (Study 1, Study 2, Study 3).
Found naturally in some fruits and vegetables, and may be added to sugar free gums, mints and some medicines. Polys also appear on nutrition labels in the form of additives, which are listed below, so make sure to read food labels! The Turku studies first established the linkage between polyols and IBS.
Found in wheat, rye and barley, Fructans contribute the most foods to the high-FODMAP list. Research breakthroughs in the mid 2000s helped scientists better understand the influence of fructans on IBS.
For a long time, patients have recognized that certain foods can trigger gastrointestinal symptoms (including flatulence, diarrhea, abdominal bloating, and discomfort). Recognized food “culprits” have included milk and other dairy products, legumes and pulses, cruciferous vegetables, some fruits, and grains (especially wheat and rye). Many of these foods are known as “gas‐producing foods” and were recommended to be avoided in situations of excessive flatulence and bloating. However, such foods were in lists without any linking of common components. Consequently, dietary advice pertaining to such foods was haphazard and without structure. Over the last five decades, however, advances in science and technology have allowed researchers to recognize that the food components that are present in such foods that may be responsible for these effects can be recognized.
Like many digestive issues, everything starts in the intestines. Because high-FODMAP foods are difficult to digest, the bacteria in both your small and large intestine begin to ferment them. While this is completely normal, the fermentation process can cause gas. FODMAPs may also draw water into your digestive system, which can lead to bloating.
The FODMAP approach for an IBS diet has gained traction in both academia and with practitioners. Although its roots date back to the 1960s, researchers had not isolated the the impact of high FODMAP foods in blind studies until the early 2000s. A top-down approach using physiological markers helped researchers identify the full range of 'FODMAP' foods. This foundation helped identify its efficacy as a treatment option for Crohn's disese in addition to IBS. The Low FODMAP Diet has caught on for multiple reasons:
Since IBS symptoms and manifestation differ so vastly from person to person, the trick to providing relief from this condition involves identifying what specifically triggers your IBS. The FODMAP approach allows you to do just that. The first step to the FODMAP diet is an elimination phase, in which you completely avoid FODMAP containing foods. The second step is to slowly reintroduce FODMAP containing foods one at a time to identify which foods exacerbate IBS symptoms. Identifying which foods affect you and your IBS can provide relief from your IBS symptoms and allow you to have more control over your condition.
Following a low FODMAP diet can be tricky at times. The diet entails eliminating high FODMAP foods and then eventually working to add them back in one at a time to identify IBS triggers. The first 2-4 weeks are known as the elimination phase. The following 4-8 weeks are used to add previously eliminated foods back into the broader GI or IBS Diet.

The low FODMAP diet consists of three phases: elimination, reintroduction and personalization.
Additionally, don't forget that the goal is not to eliminate FODMAPS entirely. Many healthy, nutritious foods contain FODMAPS. Sometimes, eliminating higher FODMAP foods leads to deficiencies in fiber, protein, and vitamins A, C, and D. For this reason, we highly recommend working with a Registered Dietitian / Nutritionist if you decide to implement a low FODMAP diet for IBS.
