Understanding the Connection: Gluten-Free vs. Low-FODMAP
While gluten-free and low-FODMAP diets often overlap, they are not the same. A gluten-free diet eliminates the protein gluten, found in wheat, barley, and rye, typically for people with celiac disease or a gluten sensitivity. The low-FODMAP diet, however, is designed to manage symptoms of Irritable Bowel Syndrome (IBS) by restricting certain types of fermentable carbohydrates (FODMAPs). Wheat, for instance, contains both gluten and high levels of fructans (a type of FODMAP). Therefore, simply choosing a gluten-free bread is not a guarantee that it is also low-FODMAP, as many use alternative high-FODMAP ingredients like high-fructose corn syrup, honey, or certain fibers.
Relying on Certified Low-FODMAP Products
One of the most straightforward ways to find a safe bread is to look for certification from reputable organizations. Both Monash University and FODMAP Friendly have created programs to test products for their FODMAP content. A certified product will carry a logo on its packaging, indicating it is safe for the elimination phase of the low-FODMAP diet in specified serving sizes. These certifications remove the guesswork, as the product's FODMAP levels have been scientifically verified.
Certified Bread Brands
Several brands offer certified low-FODMAP gluten-free options:
- Schär: A widely available brand with many certified products, including Artisan Baker White Bread, Artisan Baker Multigrain Bread, and various rolls and baguettes.
- Canyon Bakehouse: Their Mountain White and Country White breads are often listed as low-FODMAP options.
- Little Northern Bakehouse: Known for their Millet & Chia and Seeds & Grains loaves, which are certified low-FODMAP.
- COBS Bread: This Canadian bakery has a dedicated LowFOD™ line of loaves, buns, and mini-loaves.
- Helga's: An Australian brand offering certified gluten-free breads and rolls for the low-FODMAP diet.
Decoding the Ingredient Label
If a product is not certified, you must become an expert label reader. The key is to check for both the main flours and any high-FODMAP additives. Not all gluten-free flours are automatically low-FODMAP.
Low-FODMAP Gluten-Free Flours and Grains
When searching for bread, look for these safe flours:
- Rice flour (white and brown)
- Millet flour
- Sorghum flour
- Tapioca starch/flour
- Potato starch/flour
- Cornmeal/corn flour
- Buckwheat flour
- Oat flour (pure gluten-free oats)
High-FODMAP Ingredients to Avoid
Beware of these common, high-FODMAP additions often found in gluten-free products:
- Added Fibers: Inulin, chicory root fiber, and fructooligosaccharides (FOS).
- Sweeteners: Honey, agave, and high-fructose corn syrup.
- Flours: Chickpea flour, soy flour, and coconut flour (in large quantities).
- Flavorings: Onion powder and garlic powder.
- Some Grains: Amaranth flour, large amounts of certain nut flours, and large quantities of psyllium husk.
The Sourdough Exception
Traditional sourdough bread, even if made with wheat flour, can be low-FODMAP due to the fermentation process. The wild yeasts and bacteria in the sourdough starter break down the fructans during the long, slow rise, effectively reducing the FODMAP content. For those without celiac disease, a traditionally made sourdough can be a delicious, nutritious, and low-FODMAP choice. However, ensure it's made using a slow fermentation process, not with added commercial yeast, which speeds up the process and leaves more fructans intact.
Comparison of Bread Types for Low-FODMAP Diets
| Bread Type | Low-FODMAP Status | Key Consideration | Best For |
|---|---|---|---|
| Certified Gluten-Free | Yes | Look for Monash or FODMAP Friendly certification. | Those with celiac disease or gluten sensitivity following a low-FODMAP diet. |
| Standard Gluten-Free | No guarantee | Must read ingredient labels carefully for hidden high-FODMAP additives. | General gluten-free consumers; not reliable for low-FODMAP without checking ingredients. |
| Traditional Sourdough (Wheat) | Yes (for non-celiacs) | Requires a slow, natural fermentation process to reduce fructans. | Individuals managing IBS symptoms who do not have celiac disease. |
| Millet or Sorghum Bread | Yes | Naturally low in FODMAPs, but check for other high-FODMAP ingredients added. | Safe option when made with simple, low-FODMAP ingredients. |
| Multigrain Bread | Varies | Often contains high-FODMAP seeds, grains, or additives. Requires certification. | Only consume if certified low-FODMAP or made with low-FODMAP grains and seeds. |
| White Wheat Bread | Yes (small portion) | Safe only in a small serving size, typically one 24g slice. | Moderation is key for those without celiac disease. |
Tips for Shopping Smart
- Download the Monash App: The official app from Monash University provides up-to-date guidance on tested products and serving sizes, making it an invaluable tool for shopping.
- Check the Certifications: Always look for the Monash or FODMAP Friendly logos on packaging for a quick and reliable low-FODMAP option.
- Simple is Better: When in doubt, choose bread with the shortest and simplest ingredient list, made with naturally low-FODMAP flours like rice, millet, or sorghum.
- Inquire at Bakeries: If considering a bakery's sourdough, ask about their fermentation process. A true sourdough should have a long, slow fermentation without added yeast.
Conclusion
Finding a suitable bread on a low-FODMAP diet involves more than simply picking a gluten-free loaf. The key is understanding that not all gluten-free breads are low-FODMAP and that high-FODMAP ingredients can be hidden in processed products. By seeking out certified products, diligently reading ingredient labels, and recognizing low-FODMAP flour types, you can find delicious and well-tolerated bread options. Traditional sourdough is another great option for those without celiac disease, thanks to its unique fermentation process. With the right knowledge, enjoying bread again, even on a restricted diet, is entirely possible.

Making Your Own Low-FODMAP Bread
For maximum control over ingredients, consider baking your own low-FODMAP gluten-free bread at home. This allows you to specifically use low-FODMAP certified ingredients and avoid all common additives that might trigger symptoms. Recipes often call for a combination of flours, such as sorghum, rice, and tapioca, along with binders like psyllium husk to achieve a desirable texture. This is an excellent way to ensure your bread is completely safe for your dietary needs while experimenting with different flavor profiles.
