Understanding the Low FODMAP Diet
The low FODMAP diet has become a popular way of managing irritable bowel syndrome (IBS) and other digestive issues. FODMAPs refer to certain carbs that can be hard to digest for some people. By limiting high FODMAP foods and following a customized meal plan, many people find relief from IBS symptoms like gas, bloating, pain and constipation.
What Are FODMAPs?
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. These are all types of short chain carbohydrates that are poorly absorbed in the small intestine. When they continue to the large intestine, bacteria ferment them which produces gas and other issues.
Foods high in FODMAPs include:
- Fructose - found in fruits, honey, high fructose corn syrup
- Lactose - found in dairy products
- Fructans - found in wheat, garlic, onions
- Galactans - found in legumes
- Polyols - found in stone fruits, artificial sweeteners
How the Low FODMAP Diet Helps IBS
Research shows that around 70% of people with IBS find their symptoms improve on a low FODMAP diet. By restricting high FODMAP foods, less fermentation occurs in the gut. This reduces gas production, abdominal distention and pain and stool changes.
The low FODMAP diet also helps identify individual food intolerances. Foods are eliminated in phases and then systematically reintroduced. This allows people to pinpoint which FODMAPs they react to.
Three Phases of the Diet
The low FODMAP diet is implemented in three phases:
- Restriction phase - High FODMAP foods are avoided to relieve symptoms. This phase typically lasts 2-6 weeks.
- Reintroduction phase - High FODMAP foods are systematically re-challenged one at a time while monitoring symptoms.
- Personalization phase - A customized long-term diet plan is created based on individual tolerance.
This gradual process makes it easier to determine your own FODMAP sensitivities and thresholds. Dietitians stress that the low FODMAP diet should not be followed long-term without expert guidance.
Creating a Low FODMAP Meal Plan
As you being the low FODMAP diet, creating a structured meal plan can set you up for success. This involves planning balanced meals and snacks while accounting for your nutritional needs and FODMAP restrictions.
Focus on Low FODMAP Foods
In the restriction phase, focus on eating foods that are low in FODMAPs. Great options to include are:
- Protein - Eggs, fish, chicken, beef, pork, tofu, tempeh
- Non-dairy milks - Rice, almond, coconut
- Fruits - Banana, blueberry, grapefruit, orange, strawberry, kiwifruit
- Vegetables - Carrot, zucchini, tomato, spinach, eggplant, potatoes
- Grains - Rice, quinoa, gluten-free oats, tapioca
Limit High FODMAP Foods
During the restriction phase, do your best to avoid high FODMAP foods like:
- Fructose - Apples, pears, mango, watermelon, high fructose corn syrup
- Lactose - Milk, soft cheese, yogurt, ice cream
- Fructans - Wheat, garlic, onions, artichokes
- Galactans - Chickpeas, lentils, beans
- Polyols - Sweeteners like xylitol, stone fruits like apricots
Read Labels Carefully
Get in the habit of reading nutrition labels to identify hidden FODMAP ingredients. Barley, rye and high fructose corn syrup are common culprits. Also watch out for polyols used as sweeteners.
Enjoy Moderate Servings
Portion sizes matter on a low FODMAP diet. Even low FODMAP foods can trigger symptoms if consumed in large amounts. Stick to appropriate portions like 1 cup fruit, 1/2 cup veggies, 1/2 cup grains.
Hydrate Properly
Make sure to drink plenty of fluids each day. Water is ideal. Opt for herbal tea over sweetened beverages. Limit high FODMAP fruit juices.
Supplement If Needed
Restricting dairy may mean you fall short on calcium or vitamin D. A fiber deficit is also common when wheat is eliminated. Supplements can help fill nutritional gaps.

Tips for Sticking to a Low FODMAP Diet
Following a low FODMAP meal plan takes dedication but is doable with the right strategies. Here are some tips that can help:
Plan Ahead
Take time each week to map out low FODMAP meals and snacks. Make a detailed grocery list. Meal prep items like grains and proteins.
Always Read Labels
Get in the habit of checking labels for FODMAP ingredients. Look for gluten-free and dairy-free options.
Focus on Fresh Foods
Stick to basic fresh foods like produce, meats and gluten-free grains. Limit processed items which may have hidden FODMAPs.
Bring Your Own Food
When eating out, pack your own low FODMAP dishes. Choose simple meals when possible or ask about how the food is prepared.
Seek Support
Recruit friends and family to support your new diet. Join online groups to connect with others following a low FODMAP meal plan.
Work with a Dietitian
Partnering with a registered dietitian knowledgeable about FODMAPs can provide structure plus help determine your tolerance thresholds.
Potential Benefits Beyond IBS
In addition to easing IBS symptoms, the low FODMAP diet may offer other benefits including:
Improved Quality of Life
By reducing digestive symptoms, many people report improved daily functioning and wellbeing on a low FODMAP diet.
Healthy Weight
The diet encourages wholesome fresh foods. Restricting processed products may promote healthy weight maintenance.
More Energy
With less intestinal discomfort and gas, some people experience having more energy throughout the day.
Better Gut Health
Altering the gut microbiome may support a healthy intestinal environment long-term.
Reduced Inflammation
Some research indicates following a low FODMAP diet diminishes inflammatory markers. This could benefit conditions like inflammatory bowel disease.
Considerations Before Starting the Diet
A low FODMAP diet is not right for everyone. Here are some things to keep in mind:
Requires Dietary Restrictions
The diet involves eliminating many common foods which can be challenging. It's important to reintroduce FODMAPs strategically under a dietitian's care.
Risk of Deficiencies
Cutting out dairy, wheat, legumes and certain fruits/veggies raises the risk of nutritional shortfalls. Work with a dietitian to prevent deficiencies.
May Alter Gut Bacteria
Restricting FODMAPs long-term may negatively impact gut microbiome diversity. Ensure the diet is not followed continuously without reintroduction phases.
Not for Everyone
People without IBS issues will likely not benefit from a low FODMAP diet. It is specifically targeted to relieve IBS symptoms.
Requires Guidance
Work with a qualified dietitian to implement the diet properly. Self-guidance is not recommended as the diet is complex.
Sustaining Success Long-Term
The low FODMAP diet is designed to be followed short-term until symptom triggers are identified. But maintaining benefits involves several strategies:
Follow Food Reintroduction Steps
Slowly reintroducing FODMAPs in phases helps determine your unique tolerance thresholds for long-term management.
Adhere to Limits
Stay within your personalized FODMAP thresholds for foods you have identified as triggers to keep symptoms at bay.
Emphasize Good Food Sources
Focus your regular diet on nourishing low FODMAP foods like proteins, non-dairy milks, nuts, seeds, and plenty of vegetables.
Seek Ongoing Guidance
Check in periodically with your dietitian to adjust your low FODMAP plan and ensure you are nutritionally balanced.
Manage Stress
Find healthy ways to manage stress levels since stress can be a contributing IBS factor. Prioritize good sleep habits too.
