Kimchi
International · Korean
A quarter cup of kimchi, 47 g, is rated green, and half a cup, 94 g, is amber. Cabbage is not what sets that limit. Kimchi is cabbage packed with a paste of garlic, spring onion, chilli and usually something sweet, so the fructans in the jar come mainly from the seasoning rather than from the vegetable carrying it.

Breakdown for 0.25 cups
Is kimchi low FODMAP?
The green quarter cup holds 0.12 g of fructans alongside 0.05 g of excess fructose, and both double at half a cup, taking fructans to 0.24 g, still short of the 0.3 g point where the group counts as high. That is a restrained figure for a food built on alliums: one small clove of garlic, 3 g, holds 0.53 g of fructans by itself. The paste is spread thinly through a lot of cabbage and eaten a forkful at a time, and that dilution is most of the explanation. The excess fructose tracks the pear, apple or sugar that goes into most pastes.
Kimchi and IBS: what to know
Do not read the green rating as fermentation having cleared the FODMAPs out of the jar. Fructans are still there to be measured, and how much reaches your plate depends entirely on how heavy-handed you are with the tongs. Kimchi behaves as a condiment, which is what keeps it inside its serve, so the dishes to watch are the ones where it stops being a condiment. A stew or a pan of kimchi fried rice can use half a jar between two people, and a hot pan leaves fructans intact. Chilli deserves its own thought, since it can provoke urgency whatever the FODMAP figure says.
Gut-friendly ways to eat kimchi
Serve it as a side rather than a layer. A quarter cup is a generous mound next to rice, fried eggs or grilled meat, and chopping it small makes the same amount travel further through a bowl. Spring onion greens are rated green at a tablespoon chopped, 12 g, and scattered over the top they give you more of the same allium note without the bulb that carries the fructans. If it is sourness you are chasing rather than heat, sauerkraut is listed here separately and is limited by a different FODMAP group entirely.
Frequently asked questions
How much kimchi can I eat on a low FODMAP diet?
A quarter cup is the green measure, which in practice is the side dish a Korean meal actually comes with. Half a cup is amber, meaning worth a deliberate test rather than an everyday habit. Nothing beyond half a cup has been measured, so a bowl of it is unknown territory rather than a known problem.
Does kimchi contain garlic and onion?
Almost always both, and spring onion as well. That is not a reason to avoid it at the green serve, but it does explain why the portion is what matters here. For scale, a single spring onion bulb, 5 g, is rated red on 0.22 g of fructans, and a quarter cup of kimchi comes in below that while tasting of far more.
Does fermentation remove FODMAPs from kimchi?
Not enough to ignore them. The tested quarter cup still records fructans and a trace of excess fructose, and doubling the portion doubles both, which is not how a food behaves when the sugars have gone. What the numbers support is a small serve rather than a free pass, and the guide reports what is in the jar rather than what the cultures may do afterwards.
Can I eat kimchi during the elimination phase?
Yes, at the quarter cup, and it is one of the few condiments with real punch that survives a strict list. Jars vary in how much paste they carry, so start at the lower end if a new brand looks wet and heavily coated. Watch the dishes built around it, because kimchi stew and kimchi pancakes use portions no side dish ever would.
