IBS-Friendly Banana & Walnut Porridge
A soothing, gut-friendly bowl: prebiotic beta-glucans, easy-to-digest banana, and anti-inflammatory walnuts to nurture your microbiome.
Ingredients
- 40g rolled oats (certified gluten-free if you have a gluten intolerance)
- 300ml filtered water
- ½ ripe banana (approx. 60g, yellow but not overripe)
- 10g walnuts, roughly broken
- 1 pinch of ground cinnamon
- 1 pinch of fine salt
- A drizzle of maple syrup (optional, approx. 5ml)
Instructions
Preparation Steps
-
Soaking in advance (optional but recommended) — The night before, or at least 30 minutes before cooking, place the rolled oats in a bowl and cover with 300ml of cold filtered water. Soaking reduces phytates — compounds that limit the absorption of iron, zinc, and magnesium — thereby improving mineral bioavailability and making the porridge easier to digest from the very first spoonful. If you're short on time, skip straight to the next step.
-
Tip the rolled oats (drained if soaked) and water into a small, heavy-based saucepan. Bring to a medium-low heat. Gentle cooking is key here: too high a heat can break down the beta-glucans — those precious soluble fibres that feed your gut microbiome.
-
Cook for 5 to 7 minutes, stirring regularly with a wooden spoon. The oats will gradually absorb the water, taking on a smooth, creamy consistency. Add the pinch of salt and the cinnamon during cooking. Keep an eye on the texture: it should be soft and lightly bound — neither too runny nor too thick. If needed, add a splash of hot water to adjust.
-
While the porridge is cooking, prepare the banana. Peel the half banana and slice it into rounds roughly 5mm thick. Choose a banana that is yellow and firm: an overripe banana (with black spots) is higher in simple sugars and fructose, which can trigger digestive discomfort in people sensitive to IBS. A barely ripe banana contains more resistant starch, which is beneficial for the microbiome.
-
Remove the saucepan from the heat and pour the porridge into a generously sized bowl. Leave it to rest for 1 to 2 minutes off the heat: this partial cooling encourages the formation of resistant starch, a natural prebiotic that lowers the glycaemic index of the meal and feeds the beneficial bacteria in your gut.
-
Arrange the banana slices on top of the porridge, then scatter over the broken walnuts. Walnuts provide short-chain omega-3 fatty acids (ALA) with gut anti-inflammatory properties — just be mindful not to exceed 10g per serving if you are sensitive to high-FODMAP foods.
-
Add a drizzle of maple syrup if you'd like a touch of extra sweetness (it is better tolerated than honey for those in the low-FODMAP elimination phase). Serve immediately and eat slowly, chewing thoroughly: digestion begins in the mouth, and taking time over your meal can significantly reduce bloating.
Gut-Friendly Tips & IBS Adaptations
For an overnight version (even gentler on the gut): mix the rolled oats and water in an airtight jar the evening before and refrigerate overnight. In the morning, simply add your toppings without any cooking. This method preserves more intact beta-glucans and resistant starch, and lowers the glycaemic index further.
If you are following a strict low-FODMAP elimination phase: swap the walnuts for 1 tablespoon of pumpkin seeds (10g), which are naturally very low in FODMAPs and a great source of zinc and magnesium.
If you don't tolerate banana: replace it with 5 to 6 fresh sliced strawberries or 1 kiwi cut into pieces — both are low in FODMAPs and excellent for gut motility.
Why cinnamon? Beyond its warming, comforting aroma, cinnamon has carminative properties (helping to reduce gas) and supports postprandial blood sugar stability, limiting the energy fluctuations that can affect the gut-brain axis.
