Banana, Blueberry & Lactose-Free Yogurt Smoothie

Preparation Steps

1. Prepare your ingredients: Remove the frozen blueberries from the freezer and leave them to rest at room temperature for 2 to 3 minutes. Peel the banana and roughly chop it into 3–4cm rounds. If you'd like an even colder, creamier smoothie, you can use a banana that has been frozen in advance — simply peel and slice it before freezing.

2. Blend the blueberries first: Place the blueberries into the blender on their own and blitz for 15 to 20 seconds on a moderate speed. This step matters: blending the blueberries separately allows their flavonoids (powerful antioxidants) to be released before coming into contact with the banana. This is important because polyphenol oxidase (PPO), an enzyme naturally present in bananas, can reduce the absorption of these valuable compounds by up to 84% if both fruits are blended together from the start.

3. Add the banana and plant-based milk: Add the chopped banana and plant-based milk to the blender. Blend again on a moderate speed for 20 to 30 seconds, until smooth and creamy. Avoid over-blending — excessive blending generates heat through friction, which can degrade both the fibre and antioxidants in your smoothie.

4. Stir in the lactose-free yogurt: Add the lactose-free yogurt directly to the blender and mix briefly on a low speed for around 10 seconds, just long enough to incorporate it. The yogurt contributes live probiotics that support a healthy gut microbiome by encouraging the production of short-chain fatty acids (SCFAs). A short, gentle blend at this stage helps preserve those active cultures.

5. Add the optional extras: If you're using chia seeds or ground ginger, add them now by stirring with a spoon or giving the blender one brief pulse. The chia seeds will absorb a little of the liquid and provide additional fibre, which is beneficial for digestive transit. Ground ginger has anti-inflammatory properties and may help ease digestive discomfort.

6. Taste and adjust: Pour the smoothie into a large glass. Have a taste, and if you'd like a touch of extra sweetness, add a drizzle of honey or maple syrup and stir gently with a spoon.

7. Drink straight away: Enjoy your smoothie immediately — ideally within 5 minutes of making it. Oxidation rapidly breaks down antioxidants and vitamins once the smoothie is prepared, and this is also when the probiotics from the yogurt are at their most active.

💡 Gut-Friendly Tips & Adaptations

• IBS / Low-FODMAP: Opt for a slightly green banana (lower in fructans and therefore easier on sensitive guts) and keep to a maximum of 125g of blueberries. Check that your lactose-free yogurt does not contain added inulin or fructo-oligosaccharides — these are sometimes included as synthetic prebiotics and may not be well tolerated if you have IBS.

• To maximise probiotic benefits: Choose a lactose-free yogurt that clearly states the presence of live cultures (Lactobacillus, Bifidobacterium) on the label, and make sure it has not been pasteurised after fermentation.

• Creamy low-FODMAP alternative: Replace the banana with ¼ of a ripe avocado for an equally smooth and velvety texture — without the fructans — and with the added benefit of healthy fats that support the gut-brain axis.

• Storage: This smoothie will keep for up to 12 hours in the fridge in an airtight container, though the nutritional benefits are at their peak when consumed fresh.
