The easiest low FODMAP snacks are the plain ones: a small handful of nuts, a boiled egg, hard cheese with rice crackers, popcorn, lactose-free yogurt with a few blueberries. Add a protein to a low FODMAP carbohydrate, keep to one portion, and you have a snack that travels well and takes almost no time. Below you'll find 15 ideas for home and on the go, a full energy ball recipe, a few Halloween treats, the label traps to watch for and when to ask a dietitian. The diet is meant to be temporary and is best followed with a doctor or dietitian.
In brief:
- Pair a low FODMAP carbohydrate with a protein, in one portion.
- Leave 2 to 3 hours between meals and snacks.
- Check portions in the Monash FODMAP app and read labels.
- Sweet treats are occasional, not a daily habit.
- Talk to a professional before starting an elimination diet.

FODMAPs are short-chain carbohydrates that some people digest poorly. Monash University, where the diet was developed, describes it as a short period of strict restriction, usually 2 to 6 weeks, followed by a step-by-step return of foods to find out which ones you tolerate (Monash University FODMAP). Snacks are where many people get stuck: bars, crackers, granola and dried fruit are often full of wheat, honey, inulin or sweeteners ending in "-ol". The good news is that a short list of simple foods covers most of what you need.
Low FODMAP snacks: the four-step formula
Most low FODMAP snacks follow the same pattern. Once you know it, you can improvise instead of searching for a recipe every time you are hungry.
- Pick a base. Nuts or seeds, hard cheese, plain rice cakes or rice crackers, popcorn, a boiled egg, or lactose-free yogurt.
- Add one fruit or vegetable. A few strawberries or blueberries, a firm banana, or carrot and cucumber sticks.
- Check the portion and the label. Look up the serving in the Monash FODMAP app and read the ingredient list for garlic, onion, honey, inulin and sweeteners such as sorbitol or xylitol.
- Wait before the next one. Monash suggests leaving 2 to 3 hours between meals and snacks, so that FODMAPs don't add up in the gut (Monash, FODMAP stacking explained).
Step four is the one people skip. Dietitians call the effect "FODMAP stacking": several servings that are fine on their own can add up when eaten close together. Monash adds that if your symptoms are well controlled, there is no need to worry about it.
15 easy low FODMAP snacks
Here is a mix of no-prep options, snacks for work, and a few sweet ones. The portions come from a dietitian's list (see the sources); amounts for other items are not fixed, so check the app.
No prep, easy to carry
- Nuts and seeds. About 10 almonds, or 2 tablespoons of pumpkin seeds. Monash also suggests a small handful of almonds or walnuts. Cashews and pistachios are on the high FODMAP side, so skip them in mixes.
- Fruit in one portion. For example 10 strawberries, 20 blueberries or one firm banana.
- Carrot, cucumber and red bell pepper sticks with a low FODMAP dip made without garlic or onion.
- Plain popcorn. Choose plain and add your own olive oil and salt.
- Rice cakes or rice crackers with peanut or almond butter. About one tablespoon of nut butter is a typical serving.
- A boiled egg.
- A small tin of tuna or salmon with rice crackers.
- Hard cheese with plain crackers. Check the cracker label for garlic and onion powder.
- Lactose-free yogurt with blueberries and pumpkin seeds.
For work or school
- Roasted chickpeas, in a small portion. Chickpeas are a legume, so check the serving size in the app before you make them.
- Banana with peanut butter. Use a firm banana.
- Oat energy balls (the full recipe is below).
Sweet and occasional
- A square of dark chocolate. One dietitian's list gives 30 g of dark chocolate (and 15 g of milk or white chocolate) as a portion, and a Spanish dietitians' guide gives 20 g of dark chocolate without milk or fructose.
- Baked pineapple with ginger and mint. This is recipe 69 in the book below.
- Roasted cinnamon sweet potato chips. This is recipe 65 in the book; check the sweet potato serving in the app.
Many of these also appear in Monash's own snack suggestions: a small handful of almonds or walnuts, eggplant dip with vegetable sticks, an orange or banana with low lactose yogurt, cheese with seeded crackers, a small tin of salmon or tuna, a boiled egg and plain popcorn (Monash).
A low FODMAP snacks recipe: cinnamon maple oat energy balls
These no-bake balls follow the idea of recipe 66 in the book, but the quantities are ours. They keep well in the fridge, so they are good for the week ahead.
Cinnamon maple oat energy balls (about 12 balls, 15 minutes plus 30 minutes in the fridge)
- 1 cup (100 g) rolled oats
- ½ cup (125 g) smooth peanut butter, with no added sugar or honey
- 3 tablespoons maple syrup
- 2 tablespoons pumpkin seeds
- 1 teaspoon cinnamon
- A tiny pinch of salt
- Stir the peanut butter and maple syrup together in a bowl until smooth.
- Add the oats, pumpkin seeds, cinnamon and salt, and mix well. If the mixture is too crumbly, add a teaspoon of water.
- Roll into about 12 small balls with damp hands.
- Chill for 30 minutes. Keep in a closed container in the fridge for up to a few days.
One or two balls make a snack. Leave out the peanut butter if anyone at the table has a peanut allergy, and look for a seed butter with no added FODMAPs instead.
Snacks for Halloween and parties
If you are looking for low FODMAP Halloween candy, most store-bought sweets are a gamble. Sweets are often made with honey, high-fructose corn syrup or sweeteners ending in "-ol", which the National Institute of Diabetes and Digestive and Kidney Diseases lists as examples of foods that contain FODMAPs (NIDDK). Some simpler options:
- A small piece of plain dark chocolate, with the label checked.
- Popcorn with a little cinnamon and maple syrup.
- Oat energy balls shaped into small "pumpkins" and rolled in cinnamon.
- A fruit plate with strawberries, grapes and orange segments.
Sweets are best kept occasional. The book below says the same about its own snacks and desserts: a few times a week is fine, every day is not recommended.
Ingredients to avoid in snacks
| Common snack | Why it can be a problem | Easy swap |
|---|---|---|
| Granola and cereal bars | Wheat, honey, inulin, dried fruit | Plain popcorn, oat energy balls |
| Regular yogurt | Lactose | Lactose-free yogurt |
| Apple and pear slices, dried fruit | Fructose and polyols | Strawberries, blueberries, grapes |
| Cashews and pistachios | High in FODMAPs | A small portion of peanuts, walnuts or pumpkin seeds |
| Flavored chips and crackers | Garlic and onion powder | Plain rice crackers, plain popcorn |
| "Sugar-free" candy and gum | Sorbitol, mannitol, xylitol | A square of dark chocolate with a clean label |
Sources do not always agree on every food. One Spanish dietitians' guide, for instance, lists almonds among the foods to avoid, while Monash suggests a small handful. That is one more reason to use the Monash app for portions and to ask a dietitian about your own limits.
Where a cookbook can help
If you like having the meals worked out, The Delicious Low-FODMAP Diet Cookbook by Zoe Patton is a beginner-friendly option. It has 70 easy recipes, ten of them in a snacks and desserts chapter, food lists, a four-step method and a printable day-by-day plan that covers 60 days. Recipes use gluten-free grains and lactose-free dairy, and the book keeps snacks and desserts occasional. Two honest notes: the book gives yes/no food lists without serving sizes, so you will still want the Monash app for portions, and a couple of its snack recipes include foods that the book's own avoid list names (coconut milk in recipe 64, ripe banana in recipe 70), so choose with that in mind.
When to talk to a doctor or dietitian
A low FODMAP diet is not a first step to take alone. NIDDK explains that a doctor may suggest it for irritable bowel syndrome (IBS) for a few weeks and, if symptoms improve, slowly add foods back, since you may be able to eat some foods with FODMAPs without symptoms (NIDDK). Monash adds that the diet is best followed with a qualified dietitian.
See a doctor if you have ongoing bloating or pain, blood in your stool, unexplained weight loss or night-time symptoms, so that other conditions can be ruled out before you cut foods out. This article is for general information, not medical advice. The elimination phase is temporary: reintroduction and a personalized diet come next.
You'll find more practical food guides on the Books Go blog, for example low FODMAP breakfast ideas and a low FODMAP meal plan for one week, and more books on the Books Go Publications home page.
Frequently asked questions
What are good low FODMAP snacks for beginners?
Start with simple foods: a small handful of nuts, a boiled egg, plain popcorn, rice cakes with peanut butter or lactose-free yogurt with blueberries. They need no special recipe and are easy to check against the Monash app.
Are nuts low FODMAP?
Some are, in small portions. Almonds, walnuts, peanuts and pumpkin seeds are commonly listed in small servings, while cashews and pistachios are higher in FODMAPs. Sources differ on almonds, so check the current serving size in the app.
Is popcorn low FODMAP?
Plain popcorn is on Monash's list of snack suggestions. Flavored microwave popcorn often contains garlic or onion powder, so read the label or season your own.
Are there low FODMAP Halloween candies?
Plain dark chocolate in a small portion is a common choice. Many candies contain honey, high-fructose corn syrup or sweeteners such as sorbitol, so read every label, and keep sweets occasional.
How often can I eat snacks on a low FODMAP diet?
There is no single number. Leaving 2 to 3 hours between meals and snacks helps FODMAPs not to add up, and a dietitian can set a pattern that suits you.
Is the low FODMAP diet forever?
No. The strict phase is temporary and is followed by reintroduction to find out which foods you tolerate. The aim is the widest diet that keeps you comfortable.
