Breakfast is the trickiest meal on a low-FODMAP diet. Wheat toast, milky cereal, honey-sweetened granola, apple juice — most Western breakfast defaults are triggers. Below are 15 real options, every one under Monash University serving thresholds, ordered from fastest to most involved.
Before you start
Portions matter as much as ingredients. Every recipe below lists the safe serving. Weigh once or twice to calibrate your eye — after that, you’ll know intuitively what a Monash-safe portion looks like.
One slice of traditional sourdough bread with 1 tbsp of natural peanut butter. Add a few slices of well-ripened banana for extra fuel. Total prep: 3 minutes.
Safe portion: 1 slice sourdough + 20g PB + ⅓ ripe banana
170g of plain Greek yogurt (or coconut yogurt) topped with 80g blueberries, 65g strawberries, and 1 tsp maple syrup. Add 1 tbsp chia seeds for texture.
Safe portion: as listed above, one bowl
Two eggs scrambled with a knob of butter, salt, and a generous scatter of fresh chives. Serve with a slice of gluten-free toast. Zero garlic, zero onion, still full of flavor.
Safe portion: 2 eggs + 1 slice GF bread
The night before: mix ½ cup rolled oats + ½ cup lactose-free milk + 1 tbsp chia seeds + 1 tsp maple syrup. In the morning: top with strawberries and a spoonful of almond butter.
Safe portion: ½ cup dry oats + accompaniments as listed
Freeze one well-ripened banana the night before. Blend with 2 tbsp lactose-free milk, a spoonful of cocoa, and top with 20g peanut butter. Feels like dessert, works as breakfast.
Safe portion: 1 medium banana + toppings as listed
The trick with avocado is portion: only ⅛ of a medium avocado is low-FODMAP. Spread on a slice of sourdough, salt and pepper, a squeeze of lemon, and finish with chives or green onion tops.
Safe portion: ⅛ avocado + 1 slice sourdough
Two eggs whipped with a handful of baby spinach and 40g crumbled feta cheese. Cook in olive oil or garlic-infused oil for extra flavor.
Safe portion: 2 eggs + 75g spinach + 40g feta
Two rashers of grilled bacon, one fried egg, and a small handful of arugula, tucked into a gluten-free bread roll. Optional: a spoonful of homemade tomato relish (no onion).
Safe portion: 2 rashers bacon + 1 egg + 1 GF roll
½ cup cooked jasmine rice simmered with extra water into a savory porridge, topped with a soft-boiled egg, sesame oil, chopped green onion tops, and a splash of soy sauce.
Safe portion: 1 cup cooked rice + 1 egg + toppings
Mix 1 cup buckwheat flour, 1 tsp baking powder, 1 egg, 1 cup lactose-free milk, and 1 tbsp maple syrup. Fold in 80g blueberries. Cook on a hot pan with butter. Serve with more maple syrup — never honey.
Safe portion: 3 pancakes per person + toppings
A gluten-free bagel, smear of lactose-free cream cheese, 3 slices of smoked salmon, capers, dill, and a squeeze of lemon. Elegant, filling, entirely low-FODMAP.
Safe portion: 1 bagel + 40g cream cheese + salmon
Grate 1 medium zucchini, salt it, squeeze out excess water, then mix with 1 egg, 3 tbsp gluten-free flour, feta, and chives. Fry in olive oil until golden. Serve with a poached egg.
Safe portion: 65g zucchini per person + toppings
3 tbsp chia seeds soaked overnight in ½ cup lactose-free milk with 1 tsp vanilla and 1 tsp maple syrup. Layer with 80g raspberries and 20g pecans in a glass.
Safe portion: 3 tbsp chia + toppings as listed
The British classic, IBS-friendly: 1 grilled tomato, 2 rashers bacon, 1 fried egg, a small handful of grilled oyster mushrooms (button mushrooms are high-FODMAP — swap for oyster), and one slice of sourdough. Skip the beans.
Safe portion: as listed — one plate per person
Common Western breakfast staples that trigger IBS: wheat toast, most commercial cereals (they contain wheat, dried fruit, or inulin), regular milk, honey, agave syrup, apple juice, dried apricots or dates, cashew butter, and most granolas. Replace with the alternatives above.
What can I eat for breakfast on a low-FODMAP diet?
Oats (up to ½ cup dry), lactose-free milk, sourdough or gluten-free bread, eggs, plain Greek yogurt, ripe bananas (well-ripened), strawberries, blueberries, peanut butter, and firm tofu are all safe. Avoid milk, wheat cereal, apple juice, honey, and cashews.
Are oats safe for IBS?
Yes. Rolled oats are low-FODMAP at ½ cup (52g) dry weight. Portions above 1 cup uncooked become high-FODMAP due to fructans, but a normal serving is well within the safe range.
Can I have granola on the low-FODMAP diet?
Most commercial granolas contain honey, agave, dried apples, or cashews — all high-FODMAP. Make your own with oats, maple syrup, pecans, and a pinch of cinnamon, or look for a Monash-certified brand.
What milk should I use in cereal or oatmeal?
Lactose-free milk, almond milk (unsweetened), or macadamia milk are all low-FODMAP. Avoid soy milk made from whole soybeans (soy milk from soy protein is safe) and skip oat milk in servings over ½ cup.
Is coffee OK for IBS?
Coffee itself is low-FODMAP. But caffeine can trigger gut motility in some people, and the milk you add matters far more than the coffee. Try lactose-free milk or a small espresso to test tolerance.
