Navigating a low FODMAP diet can feel restrictive, especially when it comes to beloved staples like bread. However, with the right information, you can find satisfying and gut-friendly bread options. The key is understanding how specific ingredients and preparation methods affect the FODMAP content.
The Role of Fructans in Bread
FODMAPs are fermentable carbohydrates that can cause digestive issues for people with IBS. In grains like wheat, the main FODMAP is fructan. When managing a low FODMAP diet, the goal is not to eliminate gluten, but to reduce your intake of fructans. This is why some wheat-based products, processed in a specific way, can still be low FODMAP.
Sourdough: A Classic Low FODMAP Bread Option
Sourdough is often the first bread suggested for a low FODMAP diet, and for good reason. The traditional fermentation process uses a sourdough starter containing wild yeast and lactic acid bacteria. These microbes feed on the fructans in the flour, effectively reducing the overall FODMAP content of the finished loaf.
Types of Low FODMAP Sourdough
- Wheat Sourdough: A traditionally made white or wholemeal wheat sourdough is low FODMAP at a recommended serving size of two slices.
- Spelt Sourdough: Spelt is an ancient grain naturally lower in fructans than modern wheat. A traditionally fermented spelt sourdough is also a great low FODMAP choice, typically with a two-slice serving size.
Choosing the Right Sourdough
When buying sourdough, look for:
- A product made with a real sourdough starter or culture.
- A longer fermentation or proving time (some bakeries will specify this).
- Avoid 'sourdough style' loaves that rely solely on commercial yeast, which speeds up the process and does not reduce the FODMAPs effectively.
Demystifying Gluten-Free Bread
There's a common misconception that all gluten-free bread is automatically low FODMAP. This is not true. While it avoids wheat, which contains fructans, many gluten-free products use high FODMAP ingredients as fillers or binders.
How to Pick a Low FODMAP Gluten-Free Bread
- Read the Ingredients: Always check the label. Be wary of hidden high FODMAP ingredients like:
- Inulin or chicory root fiber
- Honey or high fructose corn syrup
- Apple or pear juice concentrate
- Lentil, chickpea, or soy flour
- Seek Certified Products: The easiest way to guarantee a low FODMAP gluten-free bread is to look for certification marks from Monash University or the FODMAP Friendly Food Program.
- Consider Flours: Look for products based on naturally low FODMAP flours such as rice, corn, millet, and tapioca starch.
Understanding Conventional Wheat Bread
For many, a standard wheat bread is a no-go on a low FODMAP diet, but portion size is everything. A single slice (approximately 24 grams) of standard white wheat bread has been tested by Monash University and is considered low FODMAP. However, this small serving size is often not enough for a meal, and exceeding it can trigger symptoms. Whole wheat bread generally contains higher levels of fructans and is not recommended during the elimination phase.
Comparison of Common Bread Types
| Bread Type | FODMAP Status | Recommended Serving Size | Important Notes |
|---|---|---|---|
| Traditional Sourdough (Wheat) | Low | 2 slices (approx. 109g) | Made with long fermentation; reduces fructan content |
| Traditional Sourdough (Spelt) | Low | 2 slices (approx. 82g) | Naturally lower in fructans; proper fermentation is key |
| Standard White Wheat Bread | Low, in moderation | 1 slice (approx. 24g) | High fructan content at larger servings; strict portion control |
| Gluten-Free White Bread | Varies | 2 slices (approx. 62g) | Read labels carefully; watch for high FODMAP additives |
| Gluten-Free Multigrain Bread | Varies | 1 slice (approx. 32g) | Check for high FODMAP seeds or flours; portion size is critical |
| Whole Wheat Bread | High | Avoid during elimination | Contains high levels of fructans in the germ and bran |
Low FODMAP Bread Alternatives
Beyond traditional loaves, there are other great options to explore:
- Corn Tortillas: Made with corn flour, these are naturally low FODMAP and perfect for wraps or tacos.
- Rice Cakes: A simple, crunchy option that can be topped with low FODMAP spreads like peanut butter.
- Seed Crackers: Look for crackers made with low FODMAP seeds such as chia, flax, and pumpkin seeds.
- Homemade Bread: Making your own bread allows complete control over ingredients. Using certified low FODMAP flour blends is a great option.
How to Reintroduce Bread
The low FODMAP diet is not a long-term plan but a process of elimination and reintroduction. Once you have completed the elimination phase, you can test your tolerance to different types of FODMAPs, including fructans from wheat. With a dietitian's guidance, you can determine your personal tolerance levels and expand your diet.
Conclusion
Finding bread that suits your needs on a low FODMAP diet is completely achievable. By prioritizing traditionally made sourdough and carefully selected certified gluten-free options, you can enjoy bread without compromising your digestive comfort. Always check ingredient labels, be mindful of serving sizes, and remember that professional guidance from a registered dietitian can provide invaluable support throughout this process.

A Quick Recap: What Bread Can You Eat on Fodmap Diet?
- Traditional Sourdough: The long fermentation process significantly reduces fructan levels, making wheat and spelt sourdoughs low FODMAP in moderate servings.
- Certified Gluten-Free: Check labels carefully and look for trusted certification from Monash or FODMAP Friendly, as not all gluten-free bread is low FODMAP.
- Portion-Controlled Wheat Bread: A single slice of regular white wheat bread is considered low FODMAP, but larger portions will likely trigger symptoms.
- High FODMAP Ingredients to Avoid: Steer clear of additives like inulin, chicory root, honey, and high fructose corn syrup.
- Beneficial Flours: Seek out gluten-free breads using flours like rice, corn, millet, and tapioca.
