Key Takeaways
- The low FODMAP diet is an elimination diet designed to help you determine which foods trigger your irritable bowel syndrome (IBS) symptoms.
- The low FODMAP diet should be temporary. After removing the suspected food triggers, you should systematically reintroduce them to determine which foods triggered your symptoms.
- A registered dietitian specializing in the low FODMAP diet can help guide you through the low FODMAP diet's elimination, reintroduction, and maintenance phases.
Irritable bowel syndrome (IBS) is one of the most commonly diagnosed gut disorders.
It involves abdominal pain or discomfort accompanied by changes in bowel habits such as diarrhea or constipation.
Certain food components, such as FODMAPs, have been associated with triggering IBS symptoms.
FODMAPs, which stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, are poorly absorbed carbohydrates and are highly fermentable in the gut.
The low FODMAP diet is a three-step diet used to determine food triggers and manage IBS symptoms.
It involves three phases: elimination, reintroduction, and maintenance.
During the elimination phase, you will need to avoid all high FODMAP foods.
Identifying the foods that trigger your IBS symptoms can be challenging without the proper support.

Tips for Meal Preparation Low FODMAP
Following an elimination diet like the low FODMAP diet takes some extra planning.
Batch cooking
To reduce time spent in the kitchen, consider batch cooking a few times per week.
Cook three or four servings of a recipe at once and eat the leftovers during the week.
If you don’t eat the leftovers during the week, freeze them to last longer.
Batch cooking can also help prepare lunches.
Portion your food ahead of time
Portion your lunches into individual containers at the beginning of the week so they’re ready to load into your lunch bag.
Prepping fruits and vegetables can take time.
Consider buying pre-cut or frozen vegetables and fruits.
Frozen produce is just as nutritious as fresh produce.
Use your creativity
Get creative with herbs and spices.
Since onion and garlic are off-limits on the low FODMAP diet, experiment with different ways to enhance the flavor of your meals.
Takeaway
The low FODMAP diet is a great way to determine which foods trigger your IBS symptoms.
However, following a strict low FODMAP diet long-term is not recommended because it’s very restrictive.
If you need help reintroducing foods to your diet after you’ve completed the elimination phase of the low FODMAP diet, a dietitian trained in gut health can help.
Find a dietitian near you to safely start your low FODMAP journey.
