What Is The Low-FODMAP Diet?

Starting the FODMAP diet

What Is The Low-FODMAP Diet?

A FODMAP diet is a 3 step diet used to help manage the symptoms of medically diagnosed irritable bowel syndrome (IBS). IBS is a very common gut problem with symptoms including abdominal (tummy) pain, bloating, wind (farting) and changes in bowel habit (diarrhea, constipation or both). 

The aims of the diet are to:

  1. Learn which foods and FODMAPs you tolerate, and which trigger your IBS symptoms. Understanding this will help you to follow a less restrictive, more nutritionally balanced diet for the long term that only restricts foods that trigger your IBS symptoms.
  2. Assess whether your IBS symptoms are sensitive to FODMAPs. Not everyone with IBS will improve on a low FODMAP diet. So it is important to understand whether you are among the ¾ of IBS sufferers who improve on the diet, or the ¼ of IBS sufferers who do not experience symptom improvement on the diet and therefore need to consider other IBS therapies.

A FODMAP diet is a 3 step diet.

In Step 1, you will swap high FODMAP foods in your diet for low FODMAP alternatives. For example, if you normally eat wheat-based toast with honey for breakfast, you could swap to sourdough spelt toast with jam.

The Food Guide of the Monash FODMAP App is very useful in this step of the diet. Use the simple traffic light system to identify high (red) and moderate (amber) FODMAP foods that you will swap for low (green) FODMAP alternatives. Follow the Step 1 diet for 2-6 weeks.

If your symptoms improved after 2-6 weeks on the Step 1 diet, it is time to move onto the Step 2 diet.

If they did not improve, it might be that your IBS symptoms are not sensitive to FODMAPs and you need to consider other therapies, such as stress reduction, gut directed hypnotherapy, over-the-counter medications such as laxatives, fibre supplements, or prescription medications.

Step 2

In Step 2, you continue your low FODMAP diet (as per step 1). However, you will complete a series of ‘FODMAP challenges’ to identify which FODMAPs you tolerate and which trigger symptoms. FODMAP ‘challenges’ involve eating a food rich in only 1 FODMAP group daily for 3 days and monitoring symptoms.

The diary section of the Monash FODMAP App is very useful in this step, as it lists foods that you can use for each FODMAP challenge. These foods are recommended because they contain large amounts of one FODMAP type. For instance, milk is high in lactose, but does not contain any other FODMAPs.

Very common foods (such as apple, pear, certain legumes and wheat products) that are high in two FODMAP types are also included as optional challenges in the diary (see below). After each 3-day challenge, record how well you tolerated the FODMAP(s). You can do this using a paper diary, or the Diary in the Monash FODMAP App.

The in-app Diary allows you to record challenge foods eaten, IBS symptom type and severity, bowel habit and stress levels.

Step 3

In Step 3, the aim is to relax dietary restrictions as much as possible, expand the variety of foods included in your diet and establish a ‘personalized FODMAP diet’ for the long-term.

In this step well tolerated foods and FODMAPs are reintroduced to your diet, while poorly tolerated foods and FODMAPs are restricted, but only to a level that provides symptom relief. We recommend that you repeat challenges of poorly tolerated foods and FODMAPs over time to see whether your tolerance changes.

You can also use the Filter function in the Monash FODMAP App to personalize your app experience during Step 3 of the diet.

A FODMAP diet should be followed under the guidance of a dietitian who has specialty skills in managing IBS and using a FODMAP diet. Monash FODMAP Trained Dietitians can be found on our App and website, via the Monash FODMAP Dietitian Directory. All dietitians listed in our Dietitian Directory have completed and passed our 30 hour online course on FODMAPs and IBS.

The Low FODMAP Diet Approach: Dietary Triggers for IBS Symptoms

What Is The Low-FODMAP Diet?

An Australian research team has developed a new dietary management approach – the Low FODMAP diet – to control symptoms associated with irritable bowel syndrome (IBS).

A wide number of health benefits have been attributed to some FODMAPs, which stimulate the growth of beneficial bacteria in the gut.

The “Low FODMAP diet” is not a “No FODMAP diet” and it is not a “lifetime diet.”

The low FODMAP diet requires the expert guidance of a dietician trained in the area.

After 6–8 weeks on the diet, review your progress with the dietician who will advise which foods (and how much) can be gradually re-introduced into your diet.

In Australia, the low FODMAP diet is increasingly being accepted as the primary management strategy for IBS, recently adopted by their National Therapeutic Guidelines.

IBS affects up to one in seven Americans. It is a condition that is characterized by gut symptoms including abdominal pain, intestinal gas/wind, bloating, and changed bowel habit (ranging from diarrhea to constipation). Symptoms can often be debilitating and lead to a reduced quality of life.

A wide range of therapies have been used to control IBS symptoms including various medications, bulking agents and laxatives, and a myriad of lifestyle changes. Most individuals with IBS believe that their symptoms are related to the consumption of certain foods, but advice in this area has been conflicting and confusing and offered little relief for IBS sufferers.

Understanding the FODMAP Concept

Carbohydrates can be present in different forms in foods, varying from long-chain carbohydrates (e.g. starch) to simple sugars (e.g. glucose) that are well-digested and absorbed to produce energy. Fiber and resistant starch are long-chain carbohydrates resistant to digestion and are important for stool formation and normal bowel function.

The Australian group has produced strong evidence that a group of short-chain carbohydrates, named FODMAPs (Fermentable Oligo-saccharides, Di-saccharides, Mono-saccharides And Polyols) are problematic for those with IBS. These short-chain carbohydrates are poorly absorbed in the small intestine and rapidly fermented by bacteria in the gut. The production of gas by these bacteria is a major contributor to symptoms.

A pilot study first observed that three four patients with IBS responded symptomatically to restriction of FODMAP intake. Subsequently, several high-quality clinical studies have further confirmed that improvement is due to the reduction in FODMAP intake.

Application of the low FODMAP diet is not only limited to IBS. It has also been shown to improve gut symptoms in more than 50% of patients with inflammatory bowel disease who are experiencing ongoing gut symptoms despite having inactive disease. In patients without a colon, the issue of frequent loose stool production was also reduced significantly.

The low FODMAP diet can be tailored to meet an individual’s lifestyle and preferences. Following the low FODMAP approach does not cure IBS, but allows successful drug-free management of symptoms through diet in many patients.

The low FODMAP diet: Does it work for IBS?

What Is The Low-FODMAP Diet?

FODMAP foods are foods that contain certain types of carbohydrates. They include sugars that can cause symptoms in the digestive systems of susceptible individuals. Studies have shown eating a diet low in FODMAP foods can help improve symptoms of irritable bowel syndrome.

FODMAP stands for ‘fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.’

Irritable bowel syndrome (IBS) is a widespread gastrointestinal disorder affecting 11% of the world’s population, according to a report from Clinical Epidemiology.

In this article, we look at the benefits of a low FODMAP diet, how one works, and what the research says.

Share on PinterestA low FODMAP diet may help manage symptoms of IBS.

A team of researchers from Monash University, Melbourne, Australia, developed The Low FODMAP Diet. The group, led by Peter Gibson, was the first to prove that low FODMAP diets improved IBS symptoms.

The diet plan classifies FODMAP foods as high and low. It recommends that people with IBS avoid high FODMAP foods, and choose low FODMAP foods as their daily staples.

It is important to note that serving sizes can also change how well a person tolerates a specific food. For example, a large amount of a low FODMAP food could turn it into a high FODMAP food.

Low FODMAP foods, which people can eat more liberally than medium and high FODMAP foods include:

  • Vegetables: Lettuces, carrot, chives, cucumber, fennel, eggplant, broccoli (heads or whole), zucchini, green beans, and baby spinach.
  • Fruits: Strawberries, pineapple, grapes, oranges, and kiwifruit.
  • Proteins: Chicken, beef, turkey, cold cuts, lamb, tofu, and eggs
  • Fish: Crab, lobster, salmon, tuna, and shrimp.
  • Fats: Oils, pumpkin seeds, butter, peanuts, macadamias, and walnuts.
  • Starches, cereals, and grains: Potatoes, gluten free bread, quinoa, brown rice, tortilla chips, and popcorn.

High FODMAP foods to avoid, include:

  • Vegetables: Garlic, asparagus, onions, mushrooms, beans, shallots, and scallions.
  • Fruits: Blackberries, watermelon, prunes, peaches, dates, and avocados.
  • Meats: Sausages, breaded meats, battered meats, and meats served with garlic or onion-based sauces and fillings.
  • Fish: Breaded fish, battered fish, and fish served with garlic or onion-based sauces.
  • Fats: Almonds, cashews, pistachios, and avocado
  • Starches, cereals, and grains: Beans, lentils, wheat, and gluten-based bread, rye, muffins, pastries, and pasta.

When a person knows the difference between high and low FODMAP foods, it makes it more straightforward for them to incorporate them into a diet. Both categories contain a wide range of food groups.

It is essential to talk to a doctor or dietitian before starting a low FODMAP diet. Doctors do not typically recommend this diet plan for long-term use, as it eliminates some essential, nutrient-rich foods.

However, many FODMAP foods are prebiotics, which means they support good gut bacteria.

Anyone with an IBS diagnosis who is experiencing the following symptoms might benefit from a low FODMAP diet:

  • continued gut symptoms despite lifestyle and diet changes
  • no response to stress management practices
  • no symptom relief even after removing trigger foods, such as dairy, coffee, alcohol, and spicy foods

Read about different coping strategies for IBS.

Several studies support low FODMAP diets for managing IBS symptoms.

One 2014 clinical trial compared the effects of low FODMAP diets in people with and without IBS. The study authors found that IBS symptoms improved in the low FODMAP group within a week of implementing the diet.

People saw improvements with abdominal pain, bloating, stool consistency, and flatulence.

One 2016 report in Clinical and Experimental Gastroenterology, found that up to 86% of people with IBS saw improvements in their symptoms while on a low FODMAP diet.

One current 2017 report found that low FODMAP foods provide benefits for people with IBS. It also found that certain strains and doses of probiotics may be beneficial, though more research is needed to identify the best options.

Another 2017 review concluded that low FODMAP diets offer favorable results for IBS symptoms but did not find that FODMAP diets are superior to conventional diet plans for IBS.

It is important to note that low FODMAP diets are restrictive and should be temporary.

A low FODMAP diet involves three phases:

  • Elimination: In this phase, which can last from 3–8 weeks depending on a person’s response to the diet, a person eliminates all high FODMAPs from their diet.
  • Reintroduction: Once the elimination phase is over and a person’s symptoms have returned to baseline or are significantly improved, they can start reintroducing FODMAP foods into their diet one at a time, about every 3–7 days. This can help a person identify which foods trigger their symptoms.
  • Maintenance: The maintenance phase involves returning to a regular diet as far as possible, limiting only the FODMAP foods that cause IBS symptoms. Eventually, some people may be able to incorporate all or most FODMAPs back into their diet without symptoms.

Studies show that symptoms can continue to improve for a long time after reducing FODMAPs in the diet and even after reintroducing some of them. However, people should continue to avoid the FODMAP foods that trigger their symptoms.

Useful resources for information about low FODMAP diets and specific foods to include and remove in a low FODMAP diet are the International Foundation for Gastrointestinal Disorders and the Monash University app.

Many other sites provide low FODMAP recipes and tips.

People with IBS experience a group of symptoms at the same time but do not appear to have evidence of damage or disease in the digestive system.

IBS causes the following symptoms:

  • abdominal discomfort, or pain in the abdomen
  • bloating and gas
  • a feeling that bowel movements are incomplete
  • an inability to empty the bowels
  • constipation
  • diarrhea
  • indigestion
  • nausea

Researchers do not know the exact cause of IBS. People with IBS can relieve symptoms through diet changes, medication, stress management, behavioral therapy, and various alternative therapies.

A low FODMAP diet may help improve symptoms of IBS, but not everyone responds well to this diet.

Anyone interested in starting a low FODMAP diet should talk to their doctor or a dietitian regarding the benefits and risks.

Try a FODMAPs diet to manage irritable bowel syndrome

What Is The Low-FODMAP Diet?

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that affects 1 10 people in the United States each year. With symptoms cramping, diarrhea, gas and bloating, it's no surprise that living with IBS can have a significant effect on a person's quality of life.

Diet is one way people manage IBS symptoms. A common treatment approach is to avoid the foods that trigger symptoms. Another diet for IBS, developed in Australia, is having a lot of success in managing IBS symptoms. It's called the low FODMAP diet.

What Is the Low FODMAP Diet?

FODMAP stands for “Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols. These fermentable short-chain carbohydrates are prevalent in the diet.

  • Oligosaccharides: fructans and galacto-oligosaccharides (GOS)
  • Disaccharides: lactose
  • Monosaccharides: fructose
  • Polyols: sorbitol and mannitol

Researchers discovered that the small intestine does not absorb FODMAPs very well. They increase the amount of fluid in the bowel. They also create more gas.

That's because bacteria in the colon they are easily fermented by colonic bacteria. The increased fluid and gas in the bowel leads to bloating and changes in the speed with which food is digested.

This results in gas, pain and diarrhea. Eating less of these types of carbohydrates should decrease these symptoms.

So far, studies have shown that a low FODMAP diet improves IBS symptoms. One study even found that 76% of IBS patients following the diet reported improvement with their symptoms.

Eat Less Of These Foods

  • Lactose
    • Cow's milk, yogurt, pudding, custard, ice cream, cottage cheese, ricotta cheese and mascarpone
  • Fructose
    • Fruits, such as apples, pears, peaches, cherries, mangoes, pears and watermelon
    • Sweeteners, such as honey and agave nectar
    • Products with high fructose corn syrup
  • Fructans
    • Vegetables, such as artichokes, asparagus, Brussels sprouts, broccoli, beetroot, garlic and onions
    • Grains such as wheat and rye
    • Added fiber, such as inulin
  • GOS
    • Chickpeas, lentils, kidney beans and soy products
    • Vegetables, such as broccoli
  • Polyols
    • Fruits, such as apples, apricots, blackberries, cherries, nectarines, pears, peaches, plums and watermelon
    • Vegetables, such as cauliflower, mushrooms and snow peas
    • Sweeteners, such as sorbitol, mannitol, xylitol, maltitol and isomalt found in sugar-free gum and mints, and cough medicines and drops

Eat More Of These Foods

  • Dairy: Lactose-free milk, rice milk, almond milk, coconut milk, lactose-free yogurt; hard cheeses such as feta and brie
  • Fruit: Bananas, blueberries, cantaloupe, grapefruit, honeydew, kiwi, lemon, lime, oranges and strawberries
  • Vegetables: Bamboo shoots, bean sprouts, bok choy, carrots, chives, cucumbers, eggplant, ginger, lettuce, olives, parsnips, potatoes, spring onions and turnips
  • Protein: Beef, pork, chicken, fish, eggs and tofu
  • Nuts/seeds (limit to 10-15 each): Almonds, macadamia, peanuts, pine nuts and walnuts
  • Grain: Oat, oat bran, rice bran, gluten-free pasta, such as rice, corn, quinoa, white rice, corn flour and quinoa

The idea behind the low FODMAPs diet is to only limit the problematic foods in a category — not all of them. (After all, they do have health benefits.) You may tolerate some foods better than others.

Meet with a registered dietician if you are considering this diet. It's important to make sure your eating plan is safe and healthy. He or she will have you eliminate FODMAPs from your diet. Then you gradually add the carbohydrates back in one at a time and monitor your symptoms. A food diary and symptom chart may be helpful tools.

The Bottom Line

The low FODMAP diet has shown potential in helping people with IBS. Some health professionals believe it's too restrictive. Proponents of the diet report that people stick with it because of how it improves their quality of life.

What Is a Low-FODMAP Diet

What Is The Low-FODMAP Diet?

  • Trying a Low-FODMAP Diet
  • Giving Foods Another Chance

Got digestion problems irritable bowel syndrome, bloating, or gas? A “low-FODMAP” diet might help.

Never heard of FODMAPs? They are a type of carb. But this is not your typical low-carb diet.

The diet only limits carbs that are “fermentable oligo-, di-, monosaccharides and polyols.” No wonder they came up with a nickname!

For most people, FODMAPs are not a problem unless you eat too much of them. But some people are sensitive to them.

FODMAPs draw water into your digestive tract, which could make you bloated. If you eat too much of them, they can hang around in your gut and ferment.

These types of carbs are FODMAPs:

  • Fructose: Fruits, honey, high-fructose corn syrup, agave
  • Lactose: Dairy
  • Fructans: Wheat, onions, garlic
  • Galactans: Legumes, such as beans, lentils, and soybeans
  • Polyols: Sugar alcohols and fruits that have pits or seeds, such as apples, avocados, cherries, figs, peaches, or plums

Avoiding FODMAPs doesn’t help everyone. But in a study published in the journal Gastroenterology, about 3 4 people with IBS had their symptoms ease right away after starting a low-FODMAP diet and felt the most relief after 7 days or more on the plan.

Remember, FODMAPs aren't bad. Many foods that are rich in them encourage the growth of good bacteria in the gut.

If you have gas, bloating, belly pain, diarrhea, or constipation, you might consider nixing all five forms of FODMAP carbs (lactose, fructose, fructans, sugar alcohols, and galactans) for up to 4 weeks to see if that helps. If FODMAPs are the culprit, you’ll probably start to feel better quickly.

You'll have many foods you can eat on this diet, but there's a steep learning curve about which foods are high in FODMAPs and what you could choose instead.

For example, these foods are high in FODMAPs:

  • Anything made with wheat, barley, or rye
  • Apples
  • Artichokes
  • Artificial sweeteners in chewing gum
  • Beans
  • Cashews
  • Cauliflower
  • Dried fruits
  • Garlic and onions
  • High-fructose corn syrup
  • Honey
  • Ice cream
  • Mushrooms
  • Pistachios
  • Watermelon

Low-FODMAP foods include:

  • Almond, coconut, rice, and soy milks
  • Bananas
  • Bell peppers
  • Blueberries
  • Carrots
  • Cucumbers
  • Grapes
  • Oats
  • Potatoes
  • Quinoa
  • Rice
  • Spinach, kale, and other leafy greens
  • Tangerines
  • Tomatoes

There are many other foods on the high and low lists. So it's a good idea to work with a gastroenterologist and a dietitian who can help you limit FODMAPs with a balanced diet that meets all your nutritional needs.

Once your tummy calms down, you can bring back foods one at a time at a rate of one item per week. You might discover that you’re only sensitive to one or two FODMAP carbs, not all of them.

For instance, maybe dairy is a problem, but grains are OK for you. Or maybe you have trouble digesting high-FODMAP fruits or vegetables, but nothing else is a problem.

The goal is to figure out what foods trigger your digestive problems and create a diet that gives you all the nutrients you need but only includes the FODMAPs you can handle.

What Is the Low FODMAP Diet

What Is The Low-FODMAP Diet?

cyano66/iStock/Thinkstock

any eating style that makes the news, the low FODMAP diet has generated quite a buzz. This eating plan was originally developed to help manage the symptoms associated with irritable bowel syndrome. But wait, what exactly is a FODMAP? Should you be following this diet?

What Is a FODMAP?

FODMAP is an acronym for:

Fermentable

Oligosaccharides

Disaccharides

Monosaccharides

and

Polyols

These short-chain carbohydrates are found naturally in many of the foods we eat.

These particular types of carbohydrates share three important characteristics: they may be poorly absorbed in the intestine, draw extra water into the intestine and are rapidly fermented by bacteria in the gut.

Depending on the quantity consumed and an individual's tolerance, FODMAPs can lead to increased gassiness, bloating, abdominal pain and diarrhea. FODMAPs are not inherently bad and are found in a variety of very nutritious foods.

Consult a medical professional to rule out celiac disease, cancer and food allergies or intolerances, prior to starting any new diet – especially if you’re experiencing stomach pain or intestinal problems. If a FODMAP diet is prescribed, working with a registered dietitian nutritionist is important to make sure you’re getting the nutrients you need.

Four Types of FODMAPs

There are two different groups of oligosaccharides: fructans and galactans. Fructans are found in wheat products, onions, garlic, artichokes and inulin. Galactans are found in lentils, chickpeas, broccoli, beans, Brussels sprouts and soy-based products.

The most commonly known disaccharide is lactose, which naturally occurs in milk and some dairy products and requires lactase, a digestive enzyme, for absorption. Milk, yogurt, soft cheeses, ice cream and puddings are all disaccharides containing lactose.

Fructose is a monosaccharide found in fruits. Fructose absorption is enhanced when it is combined with sources of glucose, another type of sugar. Therefore, when it comes to FODMAPs, not all fruits are equal.

Those containing equal amounts of fructose and glucose may be more easily tolerated.

Some examples of higher-fructose containing foods that may cause gastrointestinal symptoms include (but is not limited to) agave, honey, mangos, watermelon, sugar snap peas and high fructose corn syrup.

Polyols are sugar alcohols found in some stone fruits (such as cherries and nectarines), apples and pears; in vegetables such as mushrooms and cauliflower; and in some sugar substitutes containing xylitol or sorbitol.

How the Low FODMAP Diet May Work

This diet starts with a low FODMAP period, usually ranging from six to eight weeks. Then, under a medical professional's observation, a patient will gradually reintroduce certain FODMAP containing foods. During the reintroduction period, it is vital to keep track of signs and symptoms of gastrointestinal distress in order to help identify food offenders.

Reintroduction is important because over-restriction can cause harm too. Cutting too many fruits, vegetables, plant-based proteins and dairy foods from the diet can lead to increased risk of deficiencies in nutrients such as fiber, minerals such as calcium, protein (for vegetarians or vegans) and vitamins A, C and D.

A registered dietitian nutritionist can help manage the reintroduction phase by developing an eating plan that meets an individual's nutrient needs. Remember, this is a low FODMAP diet, not a no FODMAP diet; it is a highly individualized therapy that was designed to help manage symptoms, not to cure them completely.
