Low-FODMAP breakfast: what to eat and what to skip
Breakfast is the easiest meal to get right on a low-FODMAP diet, and the easiest to get wrong — muesli, wheat toast and a milky latte can stack three trigger groups before 9 a.m. Here are the swaps, the portions and five plates that work.
Cereals, oats and bread
The breakfast base decides most of your FODMAP load for the morning.
Rolled oats (1/2 cup dry)
Low FODMAP
Half a cup of uncooked rolled oats is low FODMAP. Larger bowls add fructans, so measure rather than eyeball.
Overnight oats with lactose-free milk
Low FODMAP
Same half-cup limit. Sweeten with maple syrup and top with strawberries or blueberries instead of dried fruit.
Traditional sourdough (spelt or wheat)
Low FODMAP
Long fermentation breaks down most fructans — about two slices of genuine slow-fermented sourdough is well tolerated.
Gluten-free toast
Low FODMAP
A reliable option, but check for inulin, chicory root fibre and apple juice concentrate in the ingredient list.
Cornflakes and rice puffs
Watch the portion
Plain corn and rice cereals are fine at about 1 cup. Many add honey, dried fruit or wheat — read the box.
Muesli and granola
High FODMAP
Usually built on raisins, dates, apple, cashews, pistachios or honey. One of the most common breakfast triggers.
Wheat toast, bagels, croissants
High FODMAP
Standard wheat bread is high in fructans in normal breakfast serves.
Bran and wheat-biscuit cereals
High FODMAP
Concentrated wheat fructans plus a heavy fibre load first thing in the morning.
Eggs, protein and savoury breakfasts
Protein is naturally FODMAP-free — the trouble is nearly always in the sides.
Eggs, any style
Low FODMAP
Scrambled, boiled, poached or fried, eggs contain no FODMAPs at all.
Bacon and plain grilled sausages
Low FODMAP
Bacon is fine. Sausages often carry onion and garlic powder, so choose a plain butcher's variety.
Hard cheese (about 40 g)
Low FODMAP
Cheddar, parmesan, swiss, feta and brie are essentially lactose-free.
Spinach, tomato, bell pepper, courgette
Low FODMAP
Good omelette fillings. Keep tomato to one small or about 15 cherry tomatoes.
Avocado
Watch the portion
Low FODMAP at roughly 1/8 of an avocado. A whole one carries a heavy sorbitol dose.
Mushrooms and baked beans
High FODMAP
Button mushrooms are high in mannitol and baked beans are high in GOS — both classic full-breakfast triggers.
Onion or garlic in a hash or omelette
High FODMAP
Fructans dissolve into oil and sauce. Use garlic-infused oil and the green tops of spring onions instead.
Yoghurt, smoothies and drinks
Swap the milk and the fruit and most of the problem disappears.
Lactose-free yoghurt or milk
Low FODMAP
Same taste and protein without the lactose. Almond, macadamia and rice milk also work.
Strawberries, blueberries, kiwi, orange
Low FODMAP
Low FODMAP in normal serves — about 10 strawberries, 1 kiwi or 1 orange.
Black coffee or tea
Low FODMAP
Fine on FODMAPs, though caffeine itself can speed up the gut for some people with IBS.
Unripe banana
Watch the portion
One medium firm banana is low FODMAP; ripe bananas gain fructans, so use about a third.
Regular milk lattes and cappuccinos
High FODMAP
A large milk-based coffee is a big lactose dose. Ask for lactose-free or almond milk.
Apple, pear or mango juice and smoothies
High FODMAP
High in excess fructose and sorbitol, and juice concentrates the dose with no fibre to slow it.
Honey and agave toppings
High FODMAP
Excess fructose. Maple syrup and table sugar are the low-FODMAP sweeteners for breakfast.
Five breakfasts that work
- Two eggs scrambled with spinach and a slice of sourdough, plus black coffee.

- • Dried fruit: raisins, dates, dried apple, dried mango
- • Cashews and pistachios in granola
- • Onion and garlic powder in sausages and hash browns
- • Milk, milk powder and whey concentrate
- • Sorbitol, mannitol, maltitol and xylitol in 'no added sugar' options
- • Wheat flour high in the ingredient list
Frequently asked
What can I eat for breakfast on a low-FODMAP diet?
Eggs, bacon, hard cheese, half a cup of rolled oats, genuine sourdough or gluten-free toast, lactose-free yoghurt, strawberries, blueberries, kiwi, orange, peanut butter and black coffee are all low FODMAP in standard serves.
Are oats low FODMAP?
Yes, in portion. Half a cup of uncooked rolled oats is low FODMAP; a full cup crosses into moderate fructans and GOS. Steel-cut oats have a slightly smaller safe serve at about a quarter cup dry.
Is sourdough bread low FODMAP?
Traditional slow-fermented sourdough is, because the long fermentation breaks down most of the fructans in the flour. Supermarket loaves labelled 'sourdough' but made quickly with added yeast do not get the same benefit.
Are eggs OK with IBS?
Eggs contain no FODMAPs at all, so they are one of the safest breakfast foods. If eggs still bother you, it is likely fat content or a separate sensitivity rather than FODMAPs.
Can I have coffee on a low-FODMAP diet?
Black coffee and espresso are low FODMAP. Large milk-based drinks are the problem — a regular latte is a significant lactose dose, so ask for lactose-free or almond milk.
Why is granola high FODMAP?
Most granola combines several triggers at once: raisins or dates, apple juice concentrate or honey, cashews or pistachios, and sometimes wheat. Even a small bowl stacks multiple FODMAP groups.
Can I eat a banana for breakfast?
A firm, unripe banana is low FODMAP. As bananas ripen they build up fructans, so keep a ripe one to about a third of the fruit.
