Standard naan is not low FODMAP. It’s made with wheat flour, which contains fructans, and most recipes include garlic, yogurt, or both, adding further FODMAP load. A typical piece of restaurant or store-bought naan can easily exceed the low FODMAP threshold for fructans alone, before you even account for the toppings.
Why Regular Naan Is High FODMAP
Naan is traditionally made from all-purpose wheat flour (or sometimes a mix of wheat and whole wheat), combined with yogurt, butter, and often garlic. Each of these ingredients brings its own FODMAP concerns, and in naan they stack on top of each other.
Wheat flour is the biggest issue. Wheat-based products contain fructans, a type of carbohydrate that ferments in the gut and triggers symptoms in people with IBS. Raw wheat typically contains 0.7% to 2.9% fructans by dry weight, and the low FODMAP cutoff sits below 0.3%. A single piece of naan uses enough flour to push well past that line. Small servings of wheat-based bread can sometimes stay within safe limits, but naan portions tend to be large and doughy, making portion control difficult.
Garlic compounds the problem. The fructans in garlic are water-soluble, meaning they don’t cook out in a dry or oil-based preparation like naan baking. When garlic is mixed into the dough or pressed on top before baking, the full fructan content stays in the bread. Even garlic powder, which is concentrated, delivers a significant fructan dose in a small amount. Yogurt, another common naan ingredient, adds lactose to the mix, which is a separate FODMAP category that affects people with lactose sensitivity.
Garlic-Infused Oil as a Workaround
If you’re making naan at home, you can get garlic flavor without the fructans by using garlic-infused olive oil. Because fructans dissolve in water but not in oil, heating garlic cloves in oil and then removing them leaves the flavor behind while keeping the fructan content negligible. Brushing this infused oil on top of your naan gives you that familiar garlic naan taste. This trick works only when the garlic solids are fully removed. Leaving minced garlic in the oil or using garlic powder defeats the purpose.
Making Low FODMAP Naan at Home
The most reliable way to eat naan on a low FODMAP diet is to swap the wheat flour entirely. Several flour blends work well for flatbreads. A combination of white rice flour, tapioca flour, and precooked corn flour produces a pliable dough that mimics the chewiness of traditional naan. Oat flour and cassava flour are other options, though cassava-based doughs may need extra liquid to reach the right consistency.
One tested blend uses roughly 60 grams of precooked corn flour, 40 grams of tapioca flour, and 40 grams of white rice flour per batch of four flatbreads. You shape each portion on a surface dusted with tapioca flour to prevent sticking. The result won’t be identical to wheat naan, but it gets close enough to serve alongside curry without triggering symptoms.
For the rest of the recipe, replace dairy yogurt with a lactose-free version or use coconut yogurt. Brush with garlic-infused olive oil instead of butter mixed with garlic. These swaps remove every major FODMAP source while keeping the flavor profile recognizable.
Does Sourdough Fermentation Help?
There’s growing evidence that long sourdough fermentation can break down fructans in wheat. Certain bacteria naturally found in sourdough starters produce enzymes that chop fructan molecules into simpler sugars your small intestine can absorb before they reach the large intestine, where they would otherwise ferment and cause gas, bloating, or pain. One lab study found that sourdough fermented with a specific bacterial strain reduced fructan content in a wheat-based product to below the low FODMAP cutoff.
In practice, though, this is hard to apply to naan. Traditional naan uses commercial yeast or baking powder for a quick rise, not a long sourdough fermentation. Even if you made a sourdough-style naan with an extended ferment, the degree of fructan reduction depends on the specific bacteria in your starter, the fermentation time, and the temperature. Without lab testing, you can’t know whether the fructans dropped enough. Sourdough bread from artisan bakeries with very long fermentation times (24 hours or more) may be better tolerated by some people, but this isn’t a guaranteed low FODMAP strategy for naan.
What About Store-Bought Options?
Some brands sell gluten-free naan in grocery stores, and a few are marketed as FODMAP-friendly. Check the ingredients list carefully. The flour blend matters (rice flour and tapioca starch are safe; chickpea flour is not), and many commercial naans still include garlic, onion powder, or honey, all of which are high FODMAP. If the label lists “natural flavors” without specifics, it may contain onion or garlic extracts.
Your safest bet is a product certified by Monash University or another FODMAP testing program, or one where you can verify every ingredient against a reliable FODMAP app. Failing that, homemade naan with controlled ingredients gives you the most certainty.
