Low FODMAP food list

349 foods, with the FODMAP group each one carries, how heavy the load is, how long symptoms usually take to show up, and what actually reduces them. Free, no sign-up.

Read this before you cut anything out. A high FODMAP rating means a food is a plausible suspect, not that it is your trigger. Most people react to only one or two of the six groups. Use this list to narrow down what to test, then test one thing at a time rather than removing them all at once.

Vegetables 66

Artichoke

High FODMAP

also called globe artichoke

Among the highest fructan vegetables (Jerusalem artichoke/sunchoke especially, often used as inulin source).

Fructans Within ~2 h

Artichoke hearts (canned or marinated)

also called beansprouts, mung bean sprouts

Mung bean sprouts are low-FODMAP despite the name – a safe stir-fry/garnish vegetable.

Within ~2 h

Beetroot

Moderate

also called beet, beets, red beet

Fresh beetroot high in fructans at larger servings; small amounts and canned/pickled tolerated better.

FructansGOS Within ~2 h

Bell pepper (red/green)

Low FODMAP

also called capsicum, sweet pepper

SAFE in normal servings. (Red has trace excess fructose at very large amounts.)

Within ~2 h

Bok choy

Low FODMAP

also called pak choi, chinese cabbage

Low-FODMAP Asian green (unlike most brassicas) – a safe stir-fry vegetable.

Within ~2 h

Broccoli

Moderate

also called broccoli florets, broccoli stalk

Florets are low-FODMAP in small servings (~1/2 cup); stalks higher in fructans. Sulfur compounds and insoluble fibre also produce gas independent of FODMAPs.

Fructans cruciferousinsoluble fibre Within ~2 h

Brussels sprouts

Moderate

also called brussel sprouts

Tolerable in small servings but classic gas producer via raffinose, fructans and sulfur compounds.

Fructans cruciferousinsoluble fibre Within ~2 h

Butternut squash

Moderate

also called butternut pumpkin

Mannitol; ~1/4 cup is low, larger servings moderate. Kabocha/Japanese pumpkin is lower; canned pumpkin sits between.

Mannitol Within ~2 h

Cabbage

Sorbitol cruciferousinsoluble fibre Within ~2 h

Carrot

Low FODMAP

also called carrots, baby carrots

SAFE. Reliably low-FODMAP, no known FODMAP at any normal serving.

Within ~2 h

Cassava (yuca)

Moderate

also called yuca, manioc, tapioca root, cassava

Starchy root (also tapioca/garri). Naturally low in FODMAPs but resistant-starch rich, so big servings ferment and cause gas/bloating.

2 to 6 h or later

Cauliflower

High FODMAP

also called cauliflower florets, cauliflower rice

High in mannitol (a polyol) even at small servings; commonly underestimated trigger because it's seen as a 'healthy' swap.

Mannitol cruciferousinsoluble fibre Within ~2 h

Celeriac (celery root)

Moderate

also called celeriac, celery root, celery knob

Celery-root; a mannitol source that's easy to miss because it's distinct from stalk celery.

Mannitol 2 to 6 h or later

Celery

Moderate

also called celery stalk, celery juice

Mannitol rises sharply with serving – up to ~1/4 medium stalk is low, a full stalk or celery juice is high. Easily overlooked because it seems like 'just water and fibre'.

Mannitol Within ~2 h

Chicory leaves

Moderate

also called witlof, Belgian endive, radicchio leaves

The leaves carry far less inulin than chicory root, so a salad portion is usually fine even though chicory root fibre is a major trigger.

Fructans 2 to 6 h or later

Chives

Low FODMAP

also called fresh chives, chopped chives

Low-FODMAP allium tolerated in normal culinary amounts; safe onion-flavour alternative.

histamine Within ~2 h

Fennel bulb (large serving)

Moderate

also called fennel bulb, florence fennel

The raw bulb is fructan-moderate at >1/2 cup. Distinct from fennel SEED / fennel tea, which are soothing and listed separately.

Fructans Within ~2 h

Garlic

High FODMAP

also called fresh garlic, garlic clove, garlic powder, minced garlic, black garlic, dehydrated garlic

Extremely fructan-dense even in tiny amounts; powder and black garlic test high. Garlic-infused oil (fat-based) is low-FODMAP because fructans don't leach into oil.

Fructans allium Within ~2 h

Green beans

Low FODMAP

also called string beans, French beans

SAFE in normal servings (~15 beans). Despite the name, these are low-FODMAP unlike dried legumes.

Within ~2 h

Green peas

Moderate

also called garden peas, mushy peas, petit pois

Fructans spicy Within ~2 h

Jerusalem artichoke

High FODMAP

also called sunchoke, sunroot, topinambur

One of the highest-inulin foods there is, which is why it was historically nicknamed the fartichoke. Even small servings provoke symptoms in fructan-sensitive people. Unrelated to globe artichoke.

Fructans 2 to 6 h or later

Jicama

Moderate

also called yam bean, Mexican turnip

Marketed as a prebiotic vegetable, which is precisely the problem: the inulin that makes it prebiotic is a fructan. Small servings are usually tolerated.

Fructans 2 to 6 h or later

Low FODMAP

also called German turnip

Low in small servings, tipping to moderate fructans in large ones.

Fructans cruciferous 2 to 6 h or later

Fructans allium Within ~2 h

Lettuce / leafy salad greens

Low FODMAP

also called lettuce, rocket, arugula, mixed greens, romaine

Low-FODMAP salad bases – common safe items to speed up logging (radicchio is the one chicory-family exception, listed separately).

Within ~2 h

Mushroom (button)

also called green olives, black olives

Low-FODMAP and usually fine; brined/fermented, so a minor histamine source for the sensitive subset.

histamine Within ~2 h

Onion

High FODMAP

also called red onion, white onion, yellow onion, brown onion, onion powder, dehydrated onion

Fructans concentrated throughout the bulb; cooking and powdering do NOT reduce them. One of the most common IBS triggers. Fructans are water-soluble, so onion-infused oil (then discarded solids) is tolerated.

Fructans allium Within ~2 h

Parsnip

Low FODMAP

Low FODMAP and a useful roast-dinner substitute when other root vegetables are restricted.

2 to 6 h or later

Plantain (green/unripe)

Low FODMAP

also called cooking banana

Green plantain is low FODMAP and high in resistant starch. Ripening converts starch to sugars, which is why the ripe version is listed separately and is less safe.

2 to 6 h or later

Potato

Low FODMAP

also called white potato, boiled potato, mashed potato (no garlic)

SAFE. Low-FODMAP staple (plain). Fried/loaded versions add fat triggers.

Within ~2 h

histamine Within ~2 h

Spring onion (green tops)

Low FODMAP

also called scallion green, green onion tops, chive-like tops

Green leafy portion is low-FODMAP; widely recommended onion-flavour substitute. Still an allium so flagged for the small minority sensitive to allium aroma compounds.

allium Within ~2 h

Spring onion (white part)

High FODMAP

also called scallion white, green onion bulb, spring onion bulb

SAFE when firm/just-ripe. Ripe/overripe banana accumulates fructans and becomes moderate-high, so ripeness matters.

Within ~2 h

Banana (ripe)

Moderate

also called yellow banana, spotted banana

Fructan content rises as bananas ripen, so a firm banana is low FODMAP and a soft spotted one is not. This is one of the most common reasons people get inconsistent results from the same food.

SAFE. Removing wheat removes the fructan source (watch for added inulin/apple fibre on some labels).

Within ~2 h

Khorasan wheat

High FODMAP

also called kamut, einkorn, emmer, ancient wheat

FructansGOS insoluble fibre 2 to 6 h or later

Oat porridge (small serving)

Low FODMAP May soothe

also called rolled oats porridge, oatmeal

Half a cup of rolled oats is low FODMAP and the beta-glucan is a soluble fibre that suits many people with IBS. Larger bowls move into moderate oligos, so portion is the whole story here.

Within ~2 h

Spelt (non-sourdough)

Moderate

also called spelt, spelt flour, spelt bread, dinkel wheat

Wheat bran

High FODMAP

also called unprocessed bran, bran flakes

High fructans plus a heavy insoluble fibre load. This is the specific fibre that IBS guidance advises against, and the reason blanket 'eat more fibre' advice so often makes things worse.

Fructans insoluble fibre 2 to 6 h or later

Wheat bread

High FODMAP

also called white bread, wholemeal bread, whole wheat bread

Wheat is a major fructan source. Sourdough (long-fermented) and spelt have lower fructans. This is fructan sensitivity, NOT coeliac/gluten in most IBS cases.

GOS 2 to 6 h or later

Canned lentils

Low FODMAP

What the six FODMAP groups are

FODMAP is an acronym for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. They are short-chain carbohydrates that are poorly absorbed in the small intestine. They travel on to the colon, where gut bacteria ferment them and produce gas, and several of them also pull water into the bowel.

There are six groups, and this is the part that matters: most people react to one or two of them, not all six. Knowing which group a food belongs to is what turns a long list of banned foods into a short, testable hypothesis.

Fructans

Chains of fructose found in wheat, onion, garlic and many vegetables. The single most common trigger group, and the one people most often mistake for gluten.

GOS

Galacto-oligosaccharides, concentrated in legumes and pulses. Humans lack the enzyme to break them down, so they ferment in the colon. Onset is typically delayed.

Lactose

The sugar in milk. Only a problem if you are lactose intolerant, which is a measurable enzyme deficiency rather than a sensitivity.

Excess fructose

Fructose in excess of glucose, as in apples, mangoes, honey and high-fructose corn syrup. Fructose alongside equal glucose is usually tolerated.

Sorbitol

A polyol used as a sweetener and found naturally in stone fruit. Also draws water into the bowel, so it can loosen stools as well as cause gas.

Mannitol

A polyol found in mushrooms, cauliflower and some sweeteners. Behaves much like sorbitol.

How to read the load and onset columns

Load is how much FODMAP a normal serving carries: 174 of the foods here are low, 86 moderate and 89 high. Moderate is the interesting category, because those foods are usually fine in small amounts and only cause problems when they stack up with others across a day.

Onset is roughly how long symptoms take to appear. This is the single most useful column and the one almost every other food list omits. If you bloat two hours after lunch, the culprit may well have been breakfast. GOS from legumes in particular ferments far down the gut and frequently takes six hours or more, which is why beans get blamed for the wrong meal.

16 foods are marked may soothe. These are not cures. They are foods with at least reasonable evidence for easing symptoms, such as peppermint for cramping or ginger for nausea and gastric emptying.

The mistake this list is designed to prevent

The obvious way to use a FODMAP list is to remove everything marked high. It is also the way that reliably fails.

Cut out 89 foods at once and one of two things happens. Either you feel no better, and you have learned nothing while making your diet considerably worse. Or you feel better, and you still have no idea which of the 89 was responsible, so you are stuck avoiding all of them indefinitely. Both outcomes leave you with less food and no more knowledge.

A low FODMAP diet is meant to run as a short elimination phase of roughly two to six weeks, followed by structured reintroduction, one group at a time, at increasing portions. Reintroduction is the part that produces the answer. It is also the part most people skip, and the reason so many end up on a permanently narrow diet built on a test they never finished.

Why a general list can only take you so far

Everything on this page is population-level. It tells you what tends to affect people who react to FODMAPs. It cannot tell you what affects you, because that depends on which groups you are sensitive to, your threshold for each, and what else is going on that day.

Working that out means comparing how often you get symptoms after a given food against how often you get them anyway, over enough exposures for the comparison to mean anything. That is exactly what Minthe does, and the method is published in full if you want to check the statistics before trusting them.

Frequently asked

What does high FODMAP actually mean?

FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. They are short-chain carbohydrates that are poorly absorbed in the small intestine, so they travel to the colon where gut bacteria ferment them, producing gas. They also draw water into the bowel. High FODMAP means a food contains enough of one or more of these groups to cause symptoms in a typical sensitive person at a normal serving size.

Does a high FODMAP food mean I have to avoid it?

No, and this is the most common mistake people make with a list like this. High FODMAP means the food is a plausible suspect, not that it is your trigger. Most people react to only one or two FODMAP groups, and plenty of people with bloating react to none of them. Use this list to generate hypotheses, then test them one at a time.

Why is the same food sometimes fine and sometimes not?

Three usual reasons. Portion size matters, because FODMAP content is dose dependent and a small serving of a moderate food is often tolerated. Cumulative load matters, because several moderate foods in one day can add up past your threshold. And context matters, because poor sleep, stress and menstrual cycle all change how sensitive your gut is on a given day.

How long after eating should I expect symptoms?

It depends on the group. Polyols and carbonation can act within minutes. Fructans and fructose commonly cause symptoms within about two hours. GOS from legumes ferments further down the gut and often takes two to six hours or longer, which is why people frequently blame the wrong meal. The onset column on each food is a general guide, not a rule.

Is a low FODMAP diet meant to be permanent?

No. It is designed as a short elimination phase of roughly two to six weeks, followed by structured reintroduction to work out which groups you actually react to and at what quantity. Staying in the elimination phase long term narrows your diet unnecessarily and reduces the fibre that feeds your gut bacteria. Reintroduction is the point of the exercise, not an optional extra.

Where does this data come from?

It is the same curated food catalogue that powers the Minthe app, covering 349 foods with their FODMAP groups, typical load, expected onset timing and practical notes. It is a general reference compiled from published FODMAP research and clinical guidance. It is not a substitute for personal testing, and it is not medical advice.

This list is educational and is not medical advice. It is a general reference, not a personalised recommendation, and it cannot tell you what is causing your symptoms. A low FODMAP diet is restrictive and is best done with a dietitian where possible. If you have red-flag symptoms such as blood in your stool, unintentional weight loss, difficulty swallowing, persistent vomiting or a fever alongside gut symptoms, see a clinician rather than changing your diet.
