If you’re looking for an easy and delicious way to support your gut health, this high-fibre gut health smoothie is a total game-changer. With around 20 grams of fibre per serve, it delivers up to 80% of your daily fibre needs, making it a simple yet powerful way to nourish your microbiome and fuel your body with plants.

Your gut is home to trillions of microbes that influence everything from digestion and immunity to mood, energy levels and skin health. One of the most effective ways to support a healthy and diverse gut microbiome is through your diet, particularly by increasing fibre intake and eating a wide variety of plant-based foods.

This smoothie has been designed specifically with gut health in mind. It combines a diverse mix of fruits, vegetables and plant ingredients to deliver prebiotics, polyphenols and fibre, all of which help beneficial gut bacteria thrive. Ingredients such as oats, flaxseed, spinach and kale provide natural prebiotics and both soluble and insoluble fibre, while berries contribute antioxidant-rich polyphenols that support microbial balance. A spoonful of coconut yoghurt adds live cultures for extra probiotic support, all without any dairy or added sugars. The result is a smoothie that’s as delicious as it is functional, gut-boosting, nutrient-dense and designed to help you feel your best from the inside out.

Gut Health Tips

This smoothie really does deliver on its promise, packing around 20 grams of fibre into a single serving, which equates to roughly 80% of the recommended daily intake for women and around 60% for men. At just over 400 calories, it’s a highly efficient and nutrient-dense way to help meet fibre targets, something many people struggle to achieve on a daily basis. Unlike juicing, blending whole fruits and vegetables retains the skins, seeds and pulp, meaning all of the natural fibre remains intact and available to support digestion. That fibre plays a vital role in keeping the digestive system moving, feeding beneficial gut bacteria and supporting a healthy gut barrier. Despite common misconceptions, blending does not destroy fibre; both soluble and insoluble fibres are still present, simply broken down into a smoother texture. Soluble fibre, found in ingredients such as oats, flaxseed and bananas, helps nourish gut bacteria and supports stable blood sugar levels, while insoluble fibre from leafy greens, seeds and vegetable matter adds bulk and supports regular bowel movements. Blending may even improve the bioavailability of certain nutrients, making them easier for the body to absorb while still delivering all the gut-loving benefits of fibre. The combination of berries, leafy greens and flaxseed provides valuable plant diversity and polyphenols, which are key for a resilient and balanced microbiome, while oats, cauliflower and avocado contribute additional fibre and nourishment. Coconut yoghurt introduces beneficial live cultures and creaminess, bringing everything together into a smoothie that supports gut health on every level through fibre, prebiotics, polyphenols and probiotics working in harmony.
