This is the smoothie I make most mornings. It’s quick, filling and a good way of packing plenty of goodness into the start of the day. The kefir brings a pleasant tang and plenty of beneficial bacteria, while the berries, nuts and seeds add flavour, texture and substance.

Chia seeds and linseeds are both rich in fibre and contain valuable omega-3 fatty acids. They help make the smoothie more satisfying and contribute a gentle thickness too. Psyllium husk is the finely ground outer husk of the seeds of the Plantago plant. It's exceptionally high in soluble fibre and absorbs liquid readily, helping to support digestion and gut health. A little goes a long way, so I tend to use just a teaspoon or two rather than adding too much, as it can quickly make the smoothie very thick.
