Yes, cooked cabbage is low FODMAP when you keep to the right serving size. The amount depends on the type: green and red cabbage are commonly listed at about 75 g (¾ cup raw), savoy at 40 g (½ cup), and napa at 75 g (1 cup).
The first time I sat down with a massive bowl of sautéed cabbage during my gut-healing phase, I was terrified it would trigger a massive flare-up. Instead, cooked down slowly with bone broth and a bit of ginger, it became the ultimate soothing comfort food that my digestion actually loved. Now, I make it a staple by shredding it thin and quick-braising it with apple cider vinegar to keep those gut-loving nutrients intact without the bloat.
As a certified nutritionist, the cabbage question I hear most is whether cooking it makes a difference. The honest answer has a few parts, so here is the full picture.
Is cooked cabbage low FODMAP?
Cabbage is low FODMAP in a measured portion, whether you eat it raw or cooked. The serving size is what matters most, and it changes with the type of cabbage.
| Type | Commonly listed low FODMAP serving | Main FODMAP |
|---|---|---|
| Green (white) cabbage | 75 g (about ¾ cup raw) | Sorbitol |
| Red cabbage | 75 g (about ¾ cup raw) | Fructans |
| Savoy cabbage | 40 g (about ½ cup) | |
| Napa (Chinese) cabbage | 75 g (about 1 cup) |
These amounts are the ones reported from Monash University testing. Serving sizes are updated when foods are retested, so check the Monash FODMAP app for the latest figure. Other testing programmes list different amounts for some cabbages, which is one reason you will see numbers that do not match from site to site.
Is boiled cabbage or cooked cabbage easier on the gut than raw?
This is where people get mixed advice, so I want to be careful.
- For FODMAPs: I could not find Monash testing that shows cooking lowers the FODMAP content of cabbage. Some websites claim boiling reduces it, but treat that as unproven. Do not assume cooking lets you eat a bigger portion.
- For comfort: cabbage is high in fibre, and raw cabbage can cause gas and stomach discomfort in some people with IBS, even at a low FODMAP amount. Cooked cabbage is often gentler because the fibre is softer. That is about texture and fibre, not FODMAP content.
My practical tip: weigh your cabbage raw before you cook it. Cabbage shrinks a lot when it cooks, so ¾ cup raw ends up as roughly ½ cup cooked. Measuring after cooking makes it easy to eat more than you meant to.
In my work helping people navigate digestive wellness, well-cooked cabbage is almost always a soothing win, whereas raw slaw frequently triggers immediate bloating and discomfort for sensitive clients. Breaking down the tough fibres through slow cooking makes all the difference in how easily it digests.
Green, red, savoy and napa: what is the difference?
Is green cabbage low FODMAP? Yes, at about 75 g. Green cabbage contains the polyol sorbitol.
Is red cabbage low FODMAP? Yes, at about 75 g. Red cabbage contains fructans instead of sorbitol, which matters if you know which one bothers you.
Is savoy cabbage low FODMAP? Yes, but the portion is smaller, about 40 g (½ cup). Savoy is the one people most often overeat because the leaves look light.
Is napa cabbage low FODMAP? Yes, and Napa gives you the largest portion, about 1 cup. It is a good choice for soups and stir-fries.
Is sauerkraut low FODMAP?
Here is the surprising part. Monash found that raw common cabbage is low FODMAP at a 1-cup serving, but sauerkraut made from it is high in the polyol mannitol at the same 1 cup. Fermentation changes the FODMAP content.
That does not mean sauerkraut is off the table. Monash lists smaller servings of sauerkraut that are low FODMAP, and pasteurised fermented red cabbage has been listed at about ½ cup. For white sauerkraut, sites quote different small amounts, so check the app and start with a spoonful. Also read the label, since some jars contain garlic or onion.
How to keep cabbage low FODMAP
- Measure your portion. Use the table above and weigh it raw.
- Watch FODMAP stacking. A safe portion of cabbage can go with other foods in the same meal or day. Be careful with onion-based sauces, garlic, or wheat sides.
- Use safe flavour. Cook in garlic-infused oil and finish with chives. See Are Chives Low FODMAP?
- Start small if raw cabbage bothers you. Try a small amount of cooked cabbage and see how you feel before you increase it.
Frequently asked questions
Is cooked cabbage low FODMAP? Yes, in the serving sizes above. Cooking does not change which type you have, so stay with the portion for that type.
Is boiled cabbage low FODMAP? Boiled cabbage follows the same serving sizes. Do not assume boiling makes a bigger portion safe.
Is raw cabbage low FODMAP? Yes, in the same measured portions. If raw cabbage gives you gas, the cause may be fibre, not FODMAPs.
Is cabbage okay for IBS or SIBO? Many people with IBS tolerate small portions of cooked cabbage. If you have SIBO, work with your practitioner, since tolerance is very individual.
Why does cabbage still cause gas on a low FODMAP diet? Cabbage is high in fibre, and gas can come from fibre as well as FODMAPs. A smaller, cooked portion is a good place to start.
The short version
Cooked cabbage is low FODMAP in the right amount: about 75 g for green and red, 40 g for savoy, and about 1 cup for napa. Weigh it raw, do not assume cooking raises your limit, and treat sauerkraut as a separate food. Check the Monash FODMAP app for the latest serving sizes.
