Gentle Green Smoothie Bowl for the Microbiome and Sensitive Tummies
A soft, vibrant green bowl rich in prebiotic fibre and natural probiotics to nourish your microbiome and soothe sensitive digestive systems.
Ingredients
Smoothie base
- 1 small ripe banana (approx. 100 g), preferably frozen in slices
- 80 g fresh or frozen spinach (tender baby leaves, well tolerated)
- 120 g frozen blueberries
- 150 g plain whole-milk yoghurt with live active cultures (or a probiotic-enriched plant-based yoghurt, additive-free)
- 100 ml unsweetened oat milk (or cold water for a lighter version)
- 1 tsp fresh lemon juice
Nutritional boost
- 1 tbsp chia seeds (approx. 12 g)
- 1 tsp spirulina powder or barley grass powder (optional, introduce gradually)
- 1 tsp hulled hemp seeds
Toppings
- 2 tbsp fresh blueberries or fresh raspberries
- 1 tbsp pumpkin seeds
- 1 tbsp certified gluten-free oats (or millet flakes for a gluten-free option)
- ½ tsp extra chia seeds
- 1 thin slice of kiwi (optional, test according to individual tolerance)
- A few fresh mint leaves for freshness
Instructions
Preparation Steps
-
Prepare your ingredients in advance. If you don't already have a frozen banana, peel a ripe banana, cut it into slices and place it in the freezer for at least 2 hours beforehand. Frozen fruit is essential here: it gives the bowl a thick, creamy texture without needing to add ice, which would dilute the nutrients.
-
Pre-soak the chia seeds. In a small bowl, mix 1 tbsp of chia seeds with 3 tbsp of cold water. Stir briefly and leave to rest for 5 to 10 minutes while you prepare the rest. This chia gel increases the digestive gentleness of the seeds and optimises the intake of prebiotic soluble fibre — particularly beneficial for sensitive stomachs.
-
Layer the blender in the right order. Pour the oat milk and probiotic yoghurt into the blender first. This step matters: placing liquids at the bottom protects the live cultures from violent mechanical impact and helps the blending start smoothly with minimal effort.
-
Add the solid ingredients gradually. Add the spinach, followed by the frozen blueberries, the frozen banana slices, and the lemon juice. If you are using spirulina or barley grass powder, add it at this stage. Finish with the pre-soaked chia gel and the hemp seeds.
-
Blend using progressive speed. Start the blender on a low speed for 10 seconds, then gradually increase to full power. Blend for 45 to 60 seconds until the mixture is perfectly smooth, thick, and homogeneous. The ideal consistency resembles a soft sorbet: thick enough for the toppings to sit on the surface without sinking. If the mixture is too thick and the blender struggles, add 1 to 2 tbsp of extra cold water — no more.
-
Check the texture and colour. Your smoothie should be a deep, silky green with a slight purple hue from the blueberries. A vibrant colour is a visual indicator that the antioxidants and chlorophyll from the spinach have been well preserved.
-
Pour immediately into a chilled bowl. To extend freshness and maintain the thick texture, use a slightly chilled bowl (placed in the freezer for a few minutes beforehand). Gently pour in the smoothie.
-
Arrange the toppings with care. Scatter evenly across the surface: the fresh blueberries or raspberries, the oats (or millet flakes), the pumpkin seeds, the extra chia seeds, the kiwi slice if you tolerate it well, and a few mint leaves. These toppings are not merely decorative: placed on the surface rather than blended in, they retain their intact fibrous structure, which maximises their prebiotic effect and adds a pleasant crunchy texture.
-
Eat straight away. Enjoy this bowl within 10 minutes of preparation to make the most of the live probiotic cultures in the yoghurt, which gradually lose their activity once exposed to air. Eat slowly, chewing the toppings thoroughly: saliva contains digestive enzymes that begin breaking down the fibre right from the mouth, improving the absorption of all the nutrients.
-
Have a glass of water alongside. Drinking a large glass of room-temperature water alongside your bowl is not a small detail: the soluble fibre in the chia seeds and oats needs water to form its protective gel in the gut. This hydration supports transit, reduces bloating, and amplifies the prebiotic effect of your meal.
Notes and Adaptations for Sensitive Digestive Systems (IBS / Low-FODMAP)
If you are following a low-FODMAP diet: Limit the banana to ½ a small ripe banana (approx. 50 g) to stay within tolerated portions. Replace the oat milk with rice milk or water to avoid excess avenin. Blueberries, raspberries, and spinach are well tolerated in the quantities listed.
If you are in an introduction or reintroduction phase: Start without the green powder (spirulina / barley grass) and without the kiwi. Introduce them separately, on different days, to clearly identify your tolerance to each. Reduce the chia seeds to ½ tsp to begin with and increase gradually over several weeks.
If you are lactose intolerant: Plain yoghurt with live active cultures is generally better tolerated than regular milk, as the fermentation process pre-digests a large proportion of the lactose. If you remain sensitive, opt for a plant-based yoghurt made from coconut or soy, enriched with live cultures (check the ingredient list: "live active cultures" or "lactic ferments" should be listed).
