Prebiotic Green Banana Smoothie
A functional and nutrient-dense green smoothie designed to support gut health with a powerful dose of prebiotics from green banana, balanced with spinach, healthy fats, and protein.
For 1 serving
Peel the firm, slightly green banana and break it into 2-3 pieces. The greener the banana, the higher its resistant starch content, which is crucial for prebiotic benefits.
Add the banana pieces, packed fresh spinach, unsweetened almond milk, chia seeds, protein powder, almond butter, and optional ground cinnamon to a high-speed blender.
Top the ingredients with the ice cubes.
Secure the blender lid firmly. Begin blending on a low speed to break down larger ingredients, then gradually increase to high speed.
Blend for 60-90 seconds, or until the smoothie is completely smooth and creamy, ensuring no visible spinach flecks or banana chunks remain.
If the smoothie is too thick for your preference, add an additional splash (1-2 tablespoons) of almond milk and blend again briefly until the desired consistency is reached.
Pour the Prebiotic Green Banana Smoothie immediately into a glass and serve. This smoothie is best consumed fresh to maximize its nutrient content and texture.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Resistant Starch Power: Ensure your banana is truly green or very firm with green tips. As bananas ripen, resistant starch converts to sugar, reducing its prebiotic benefits.
- 2High-Speed Blender is Key: For the smoothest texture, especially with fibrous ingredients like spinach and firm banana, a powerful blender is highly recommended.
- 3Customize Consistency: Adjust the amount of ice and almond milk to achieve your preferred thickness. For a thicker, spoonable smoothie bowl, reduce liquid and add more frozen ingredients.
- 4Batch Prep: Measure out dry ingredients (chia seeds, protein powder, cinnamon) into individual bags or containers for quick morning assembly.

Spinach, chia seeds, and green banana contribute significant dietary fiber, aiding digestion, promoting satiety, and helping to regulate blood sugar levels.
Nutrient-Dense
Packed with essential vitamins (K, A, C from spinach), minerals (potassium from banana), healthy fats (almond butter, chia), and protein, supporting overall bodily functions and sustained energy.
Frequently asked questions
A: Green bananas are rich in resistant starch, which acts as a prebiotic, feeding beneficial gut bacteria. As bananas ripen, this resistant starch converts into simple sugars, reducing its prebiotic effect.
