Many common fruits are low in FODMAPs and safe for people managing IBS or fructose sensitivity. The list includes cantaloupe, kiwifruit, oranges, mandarins, pineapple, blueberries, strawberries, grapes, and firm (unripe) bananas, among others. The key is knowing which fruits are safe, how much you can eat, and why some fruits cause problems while others don’t.
How Fruit Gets Its FODMAP Rating
The two main FODMAPs in fruit are excess fructose and sorbitol. Fructose is a natural sugar found in all fruit, but it only becomes a problem when a fruit contains more fructose than glucose. Your small intestine absorbs fructose more efficiently when glucose is present in equal or greater amounts. So a fruit like an apricot, where fructose is balanced by glucose, typically causes no issues. A mango, which is equally high in fructose but lower in glucose, is more likely to trigger symptoms.
Sorbitol is a sugar alcohol found naturally in certain stone fruits. It’s poorly absorbed in the gut and draws water into the intestine, which can cause bloating, gas, and diarrhea. Some fruits contain both excess fructose and sorbitol, making them a double hit. Apples and pears are the classic examples.
Low FODMAP Fruits to Choose
These fruits have been tested and rated low in FODMAPs by Monash University, the research group that developed the FODMAP classification system:
- Blueberries
- Strawberries
- Cantaloupe (rockmelon)
- Honeydew melon
- Kiwifruit
- Oranges
- Mandarins
- Pineapple
- Grapes
- Firm (unripe) bananas
- Raspberries
- Papaya
- Passionfruit
- Dragon fruit
Serving size matters even with low FODMAP fruits. Eating two or three servings at once can push the total FODMAP load past your threshold. A standard serving is roughly one cup of chopped fruit or one medium whole fruit. The Monash University FODMAP app provides specific tested serving sizes for each fruit, which is useful if you’re in the elimination phase of the diet and need precision.
High FODMAP Fruits to Limit
Fruits particularly high in excess fructose include apples, pears, mangoes, cherries, figs, watermelon, and nashi pears. Fruits rich in sorbitol include apples, cherries, peaches, nashi pears, and plums. Many of these overlap, containing both excess fructose and sorbitol. This is why apples and pears are often the first fruits people with IBS learn to avoid.
Watermelon is a common surprise on this list because it seems like a light, watery fruit. But it contains significant excess fructose and is rated high FODMAP at typical serving sizes.
Why Banana Ripeness Changes Everything
Bananas are one of the most confusing fruits on the FODMAP diet because their rating depends on how ripe they are. A firm, slightly green banana is low FODMAP. A soft, spotty ripe banana is high FODMAP due to its fructan content.
This happens because fructan levels increase during storage and ripening, especially when bananas are kept in cold storage, which is now standard practice at most supermarkets. If you eat ripe bananas, Monash suggests limiting yourself to about one-third of a banana to stay in the low FODMAP range. If you prefer a full banana, choose one that’s still firm and yellow without brown spots.
Dried Fruit Is a Different Story
Drying fruit removes water but concentrates all the sugars that were in the original fresh fruit, including FODMAPs. Research from Monash University has also detected fructans in dried fruit that aren’t present in the same fruit when fresh. This means a fruit that’s safe when eaten fresh can become high FODMAP when dried.
There’s also a portion size problem. Dried fruit shrinks dramatically, so it’s easy to eat the equivalent of several servings of fresh fruit without realizing it. A small handful of dried mango, for example, could contain as much fructose as two or three fresh servings. If you’re following a low FODMAP diet, treat dried fruit with caution regardless of whether the fresh version is safe.
Does Canning or Cooking Change FODMAP Levels?
Canning and processing under acidic conditions can affect FODMAP content, but the results are inconsistent with fruit. Monash’s research found that very high temperatures may break down some FODMAPs, but the extent varies depending on the food, temperature, and cooking conditions. You can’t reliably assume that cooking a high FODMAP fruit makes it safe.
Canned fruit packed in heavy syrup adds extra fructose from the syrup itself, which can increase FODMAP levels beyond what the fruit alone would contain. If you buy canned fruit, choose versions packed in water or light juice and drain the liquid before eating.
Practical Tips for Eating Fruit on a Low FODMAP Diet
Spacing out your fruit intake helps. Eating one serving of a low FODMAP fruit at a time, with a gap of two to three hours before your next serving, keeps the total FODMAP load in your gut manageable. Stacking multiple fruits in a smoothie or fruit salad can push you past your individual tolerance even if each fruit is technically low FODMAP on its own.
During the elimination phase of the diet, stick to single fruits at tested serving sizes so you can identify your personal triggers. Once you move into the reintroduction phase, you can experiment with larger portions and higher FODMAP fruits to find your threshold. Many people discover they can tolerate moderate amounts of some “high FODMAP” fruits, particularly if they eat them alongside a meal rather than on an empty stomach.
The Monash University FODMAP app is the most frequently updated resource for specific serving sizes and ratings. Their fruit category was most recently reviewed and updated in June 2024, so the current data reflects the latest testing.
