If bloating shows up after meals that seem perfectly healthy, FODMAPs are usually the reason.
The short answer is that high FODMAP foods are a specific group of fermentable carbs — not junk food, not ‘bad’ food — and this list breaks them down by category so you can actually use it.
I’ve spent a lot of time cross-referencing my own symptom log against these categories, and the patterns are more predictable than they seem at first.
Key Takeaways
- High FODMAP foods contain fermentable carbs — fructans, GOS, lactose, excess fructose, or polyols — that some guts absorb poorly.
- Common triggers include onion, garlic, wheat, apples, pears, cashews, pistachios, and most legumes.
- Portion size matters a lot — a quarter avocado is fine, a whole one usually isn't.
- Eggs, most meats, and hard aged cheeses are naturally low FODMAP even though they're in the same category as high FODMAP foods.
- This list is a starting point for the elimination phase, not a permanent 'never eat again' list.
What Does 'High FODMAP' Actually Mean?
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols.
These are short-chain carbohydrates that some people absorb poorly, and when they reach the large intestine undigested, gut bacteria ferment them, producing gas, bloating, and cramping.
I started tracking my own triggers years ago after a stretch of unexplained bloating, and the pattern that emerged wasn’t about ‘unhealthy’ food at all.
Onions, garlic, apples, and even some beans I’d always considered wholesome turned out to be the real culprits.
If you’re just getting oriented, it helps to first skim the low fodmap foods list so you know what you can eat freely, then come back here to spot what to scale back.
One thing that trips people up constantly: FODMAP status has nothing to do with whether a food is processed or ‘clean.’
It’s purely about carbohydrate structure, which is why cauliflower and honey can be high FODMAP while a plain candy bar technically isn’t (though obviously not a health food either).
Researchers at Monash University developed the original low-FODMAP research and testing behind most of the food data used today, and their FODMAP and IBS overview is worth a look if you want the underlying science.
| FODMAP Category | What It Means | Common High-FODMAP Sources |
|---|---|---|
| Oligosaccharides (fructans & GOS) | Sugar chains the small intestine can't fully break down | Wheat, onion, garlic, chickpeas, lentils |
| Disaccharides (lactose) | Milk sugar that requires the enzyme lactase to digest | Milk, soft cheese, yogurt, ice cream |
| Monosaccharides (excess fructose) | Fructose in amounts that outpace absorption capacity | Apples, mango, honey, high-fructose corn syrup |
| Polyols (sugar alcohols) | Sugar alcohols absorbed slowly and fermented in the gut | Pears, cherries, mushrooms, cauliflower, sorbitol/xylitol |
High FODMAP Foods List by Category
I’ve organized this the way I actually think about my own plate — by category, since that’s how triggers tend to stack up in a real meal.
Dairy & Eggs
The FODMAP concern in this category comes almost entirely from lactose, the natural sugar in milk.
Eggs contain no carbohydrates and are naturally FODMAP-free, no matter how they’re cooked.
- Milk (cow, goat, sheep) — high lactose per serving; the most common dairy trigger.
- Soft cheeses (ricotta, cottage cheese) — moderate to high lactose; fresh cheeses retain more whey sugar than aged ones.
- Yogurt, especially sweetened — moderate to high lactose, worse in large portions.
- Ice cream — high lactose, plus added sugars that can compound symptoms.
- Custard and dairy-based desserts — concentrated milk sugars.
- Evaporated or condensed milk — lactose gets concentrated during processing.
- Cream-based sauces made with milk — often carry enough lactose to trigger symptoms.
Hard, aged cheeses like cheddar and parmesan are generally low FODMAP since most of the lactose is broken down during aging, per the Johns Hopkins Medicine FODMAP diet overview.
Vegetables & Leafy Greens
Plenty of vegetables are nutritious and still land on this list, because FODMAP status tracks carbohydrate type, not vitamin content.
- Onions (all varieties) — high in fructans; one of the most common triggers overall.
- Garlic — high in fructans, concentrated even in small amounts.
- Shallots — similar fructan load to onions.
- Leeks (white bulb portion) — the bulb concentrates fermentable carbs.
- Cauliflower — high in polyols; a frequent bloating trigger.
- Mushrooms (button, portobello) — high in polyols.
- Asparagus — high in fructans.
- Artichokes — dense source of fermentable fructans.
- Sugar snap peas — high in polyols.
- Beets — moderate to high FODMAP in larger servings.
Many of these same vegetables also show up on a high fiber foods list, which is exactly why cutting them out can leave a gap in your fiber intake if you’re not careful.
Fruit
Fruit triggers usually come down to excess fructose, polyols, or both — and ripeness genuinely changes the load.
- Apples — high in excess fructose; triggers even in moderate portions.
- Pears — high in both excess fructose and polyols, a double load.
- Mango — high in excess fructose.
- Watermelon — high in excess fructose despite its high water content.
- Cherries — high in polyols.
- Peaches, nectarines, and apricots — all high in polyols, fresh or dried.
- Plums and prunes — polyol-heavy, especially in dried form.
- Blackberries — moderate to high polyols past a small serving.
In my experience, ripeness matters more with fruit than with almost any other category — a slightly underripe banana behaves very differently than an overripe one.
Grains, Breads & Sweeteners
This is the category people miss most often, because ‘grain’ doesn’t sound like a FODMAP word.
- Wheat-based bread, pasta, and couscous — high in fructans.
- Rye and barley — high in fructans, common in some crackers and beers.
- Honey — high in excess fructose.
- Agave syrup — high in excess fructose.
- High-fructose corn syrup — a concentrated excess-fructose source.
- Sugar-free gum and candy with sorbitol, mannitol, or xylitol — polyols, and often a sneaky trigger since they’re marketed as ‘sugar-free.’
Gluten itself isn’t a FODMAP — it’s the fructans in wheat that cause most of the trouble, which is why gluten-free products aren’t automatically low FODMAP either.
Herbs & Spices
Pure herbs and spices are mostly fine because they’re used in such small amounts, but blends are where the risk hides.
- Vegetable seasoning powders with onion or garlic — high in fructans.
- Garlic powder blends — concentrated fructans; a common hidden trigger.
- Onion powder blends — same issue as garlic powder.
- Savory seasoning mixes and bouillon — often built on an onion/garlic base.
I always flip the package over and scan the ingredient list, because ‘natural flavoring’ on a spice blend can quietly mean onion or garlic powder.
Nuts & Seeds
Nuts are nutrient-dense, but a few varieties carry meaningful GOS (galacto-oligosaccharides) at typical serving sizes.
- Cashews — high in GOS; one of the most common nut triggers.
- Pistachios — high in GOS, similar profile to cashews.
- Mixed nuts containing cashews or pistachios — hidden inclusion makes portion control tricky.
- Honey-roasted cashews — GOS plus added sugars.
- Cashew butter — concentrated GOS in every spoonful.
Almonds and walnuts, by contrast, are generally fine in small handfuls, which is a swap worth remembering.
Beans & Legumes
Legumes are some of the most reliably high-FODMAP foods out there because of their GOS content.
- Chickpeas — high in GOS; a frequent bloating trigger.
- Lentils — moderate to high GOS depending on portion.
- Kidney beans — high in GOS.
- Black beans — high in GOS.
- Baked beans — GOS plus added sugars, which compounds the digestive load.
If you still want plant protein without the gas, canned and well-rinsed lentils in small portions are more tolerable than a full cup, and it’s worth browsing low fodmap high protein foods for options that don’t require careful portioning at all.
Why Portion Size Matters (It's Rarely All-or-Nothing)
Here’s something that surprised me early on: FODMAP status isn’t fixed — it’s dose-dependent.
A food can be low FODMAP at one serving size and high FODMAP at a bigger one.
A quarter of an avocado is generally tolerated, while a whole avocado crosses into high-FODMAP territory for most sensitive guts.
Six almonds might be fine, but twenty can start adding up, especially if they’re eaten alongside another moderate-FODMAP food at the same meal.
This ‘stacking effect’ is, in my experience, the number one thing that derails people who otherwise feel like they’re doing everything right.
Cooking and cooling certain starches, like potatoes and rice, can also change how they behave in the gut, per guidance from the Cleveland Clinic’s overview of the low-FODMAP diet.
Common Mistakes When Building a Low-FODMAP Plate
I made most of these mistakes myself before I got the hang of it.
Assuming gluten-free means low FODMAP. It doesn’t — plenty of gluten-free products still use onion, garlic, or high-fructose syrups.
Cutting out fiber along with the trigger foods. Skipping onions and beans without replacing that fiber can leave you constipated instead of bloated.
If that happens, it’s worth checking a low fodmap high fiber foods list so you’re not trading one digestive problem for another.
Staying in strict elimination indefinitely. The elimination phase is meant to be temporary, followed by a structured reintroduction to find your actual tolerance.
Not accounting for stacked servings. One moderate-FODMAP food is usually fine; three moderate-FODMAP foods in one bowl is a different story.
Smart Swaps: Low-FODMAP Alternatives
None of this means bland meals for life — it just means swapping smarter.
Onion and garlic can be replaced with the green tops of scallions, or garlic-infused oil, which carries flavor without the fermentable fructans.
Wheat bread swaps to sourdough spelt or certified low-FODMAP bread; cashews swap to a small handful of macadamias or walnuts.
If snacking is where you struggle most, low fodmap snacks is a good next stop for grab-and-go options that won’t undo your progress.
And when you’re ready to build full meals instead of just avoiding a checklist, low fodmap recipes takes the guesswork out of dinner.
Over the years I’ve learned that the goal isn’t a perfect diet — it’s knowing your own thresholds well enough to enjoy food without dread.
Frequently Asked Questions
What is a high FODMAP food, exactly?
It's a food that contains meaningful amounts of fermentable oligosaccharides, disaccharides, monosaccharides, or polyols — short-chain carbs that some people absorb poorly, which can lead to gas, bloating, and cramping.
What foods should I avoid on a high FODMAP list?
Common ones include onion, garlic, wheat, apples, pears, cashews, pistachios, most beans and lentils, and dairy with lactose like milk and soft cheese, especially in larger portions.
Is this the same as a gluten-free list?
No. Gluten-free and low-FODMAP are different systems; a food can be gluten-free and still high FODMAP, like honey or garlic, so don't assume one label covers the other.
Can I eat high FODMAP foods occasionally?
Many people tolerate small portions of high FODMAP foods just fine, since the effect is dose-dependent. The point of this list is awareness, not a lifetime ban.
How do I know which high FODMAP foods actually bother me?
The standard approach is a structured elimination phase followed by reintroducing foods one at a time to identify your personal thresholds, ideally with guidance from a healthcare professional or registered dietitian.
