Tortilla (corn)
Grains · Bread
Two small corn tortillas (50 g) are rated green together, which is a plate of tacos rather than a taste. The tested pair holds 0.02 g of fructans and registers zero for lactose, excess fructose, GOS, sorbitol and mannitol. On a diet that spends most of its time asking you to eat less of something, this is a food that hands you the second one.

Breakdown for 2 tortillas
Is tortilla (corn) low FODMAP?
A corn tortilla begins as dried field corn, steeped with lime, then ground wet into masa. That is a starchy grain crop rather than the sweet vegetable cut off a cob, which is why sweet corn is listed here as a separate food with separate limits. The figures follow the raw material: 0.02 g of fructans across both tortillas, comfortably inside the 0.1 g line for a moderate portion, with the rest of the column at zero. Plain masa leaves the bacteria in your gut with almost nothing to ferment.
Tortilla (corn) and IBS: what to know
The thing to check is the ingredients list, because plenty of supermarket “corn” tortillas are a blend with wheat flour added so they fold without cracking. A true one lists masa or maize flour, water and lime, and not a great deal else. Past that, corn tortillas suit an irritable gut well: they are small, they are rarely bulked up with the fibre additives that turn up in gluten-free baking, and two of them makes a meal instead of a ration. What goes on top is the usual question, since taco fillings run on onion, garlic and beans.
Gut-friendly ways to eat tortilla (corn)
Warm them properly and they stop being brittle: half a minute a side in a dry pan, then stacked under a tea towel so they steam themselves soft. Two of them will hold grilled chicken or fish, red capsicum, coriander, lime and feta without any arithmetic. When you want something you can roll tightly, wheat tortillas are rated green at one small round, so it is worth keeping both packets and choosing by what the meal needs. Skip the jarred salsa unless the label is clean, and build your own on tomato, lime and spring onion greens.
Frequently asked questions
How many corn tortillas can I eat with IBS?
Two small ones is the measured serve and it comes back green, with barely any fructans in the pair. That is a taco dinner, which is more than most staples on this diet will give you. A third has not been tested, so if you want more on the plate, add rice or a salad rather than another tortilla.
Are corn tortillas gluten free?
A tortilla made from masa alone is, which makes corn the sensible base if you are managing coeliac disease alongside IBS. Blended brands that add wheat flour are not, and they are common enough that reading the packet is worth the ten seconds. Gluten free and low FODMAP are separate questions, but on this particular food the answer to both happens to be the same.
Are tacos low FODMAP?
The tortillas usually are; the taco often is not. Two corn tortillas rate green, and then the meal arrives carrying refried beans, onion through the salsa, garlic in the seasoning packet and a sauce built on both. Assemble it yourself from grilled meat or fish, lettuce, tomato, capsicum, cheese and lime, and the whole plate stays comfortably green.
Why are corn tortillas low FODMAP when corn on the cob is not?
They are two different crops handled two different ways. Sweet corn is picked young and eaten as a vegetable, while tortillas are milled from field corn left to dry hard on the plant. Sweet corn has its own tested serves and its own ceiling in this guide. The tortilla is by far the more forgiving way to eat corn, and the allowance is not a small one.
