High-FODMAP foods are the everyday triggers behind a lot of bloating, gas and cramping. The tricky part is that they cut across every food group — some fruits, some vegetables, some grains, some dairy — so a simple “avoid X category” rule does not work. This list organizes the main offenders by FODMAP group, with a lower-FODMAP swap for each.
What makes a food “high-FODMAP”
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols — short-chain carbohydrates that are poorly absorbed in the small intestine and rapidly fermented by gut bacteria. There are five functional groups, and a food is “high-FODMAP” when a normal serving carries enough of one of them to cause symptoms in sensitive people.
The high-FODMAP foods list, by group
Lactose (a disaccharide)
| High-FODMAP | Lower-FODMAP swap |
|---|---|
| Cow’s milk, soft cheese, yogurt, ice cream | Lactose-free milk, hard aged cheese, lactose-free yogurt |
Fructans (an oligosaccharide)
| High-FODMAP | Lower-FODMAP swap |
|---|---|
| Onion, garlic, leek bulb | Garlic-infused oil, green scallion tops, chives |
| Wheat & rye (bread, pasta) | Sourdough spelt, oats, rice, quinoa |
| Asparagus, artichoke | Carrot, zucchini, green beans |
GOS (an oligosaccharide)
| High-FODMAP | Lower-FODMAP swap |
|---|---|
| Chickpeas, lentils, kidney beans | Canned & rinsed lentils (small portion), firm tofu |
| Cashews, pistachios | Peanuts, walnuts, macadamias |
Excess fructose (a monosaccharide)
| High-FODMAP | Lower-FODMAP swap |
|---|---|
| Apple, pear, mango, watermelon | Orange, kiwi, strawberry, firm banana |
| Honey, agave, high-fructose corn syrup | Maple syrup, table sugar (in moderation) |
Polyols (sugar alcohols)
| High-FODMAP | Lower-FODMAP swap |
|---|---|
| Stone fruit (peach, plum, cherry), mushrooms | Pineapple, grapes, oyster mushrooms (small) |
| Sugar-free gum & mints (sorbitol, mannitol, xylitol) | Regular mints, or skip |
Why portion (and “FODMAP stacking”) matters
FODMAP tolerance is dose-dependent. A small amount of a high-FODMAP food may be fine, while a large serving — or several moderate-FODMAP foods in one meal — can tip you over your threshold. This is called FODMAP stacking: half an avocado plus a few cashews plus a slice of regular bread can add up even if none alone would bother you. Spreading triggers across the day, rather than piling them into one meal, often helps.
Where digestive enzymes help
Swaps and portion control are the backbone of a low-FODMAP approach, but they come at a social cost. For four of the five groups — lactose, fructans, GOS and excess fructose — a targeted enzyme taken with the first bite can break the carbohydrate down before it ferments, which is the idea behind a complete FODMAP enzyme supplement. The honest exception is polyols: no oral enzyme breaks down sorbitol or mannitol, so those still call for swaps and portions. Onion and garlic are the most common culprits — our piece on bloating after eating garlic and onion goes deep on that one.

Fodyzen is designed to break down the FODMAPs in dairy, wheat, onion, garlic, beans and high-fructose fruit — four enzymes in one daily formula — so the list above gets a lot shorter.

What are the most common high-FODMAP foods?
The biggest everyday triggers are onion and garlic (fructans), wheat and rye (fructans), beans and lentils (GOS), milk and soft cheese (lactose), apples and honey (excess fructose), and stone fruit and sugar-free gum (polyols).
Are all fruits and vegetables high-FODMAP?
No. Plenty are low-FODMAP in normal portions — for example carrots, spinach, potatoes, oranges, strawberries and firm bananas. FODMAP content is food- and portion-specific, not a whole-category rule.
Is gluten a FODMAP?
No. Gluten is a protein, not a FODMAP. Wheat is a problem for many people because it contains fructans (a FODMAP), which is why some who think they are gluten-sensitive are actually fructan-sensitive.
Can I make high-FODMAP foods easier to tolerate?
Smaller portions, garlic-infused oil instead of garlic cloves, and the green tops of scallions all help. For four of the five FODMAP groups, a targeted digestive enzyme taken with the meal can break the carbohydrate down before it ferments. No enzyme covers polyols.
