But what’s behind this mysteriousAlong with other super healthy ingredients such as cucumber, kale and parsley, the Japanese wholefood chlorella is added to theAnd it’s not just Rosie who’s caught the chlorella bug, Miranda Kerr has admitted that she takes chlorella supplements to keep her skin Nadia Brydon, who’s a nutritionist and green food expert at Sun Chlorella, has shared her tips for the perfect morning smoothie....'With everyone from Rosie Huntington-Whiteley to Millie Mackintosh drinking green smoothies recently, you’d be forgiven for thinking this is just another beauty fad.

'We all know that we’re probably not eating enough greens, yet our greens contain the most vitamins and minerals of any foods we eat, and are the most important category of foods to consume on a daily basis to help keep us healthy.  Green smoothies can be high in vitamin B12, which can help reduce tiredness, and magnesium, which is found in dark green vegetables and can act as nature’s tranquiliser, helping to keep us de-stressed and relaxed – so it’s no wonder so many busy celebs are trying it!  You’ll notice that a lot of models are now adding green supplements to their juices, to up their nutrient intake even further. For instance, a daily serving of the Japanese wholefood Sun chlorella contains iron content equivalent to nine cups of spinach (270g) and the same B12 content as a 32oz steak. Perhaps most importantly, these drinks provide large quantities of whole food natural vitamins and minerals and help increase our daily intake of fruit and vegetables – for busy people who still want to remain healthy, this is hugely important.

Smoothies are also full of fibre and water along with a whole range of nutrients which naturally makes us feel fuller which reduces the desire to consume food generally especially sugar and carbohydrates. We recommend the Rolls Royce of blenders, the Vitamix blender, as it breaks down the cell walls of fresh, whole foods to deliver the full benefit of nutrients. It also saves time as all of the ingredients can be added at once.'Miranda and Rosie’s green juices and smoothies are so nutritious, simply because greens contain the most vitamins and minerals of any foods we eat, and are the most important category of foods to consume on a daily basis to help keep us healthy.  Combining these into an easy to drink smoothie can help busy people cram as many of these vegetables into their daily diet as possible. Juicing and blending raw green vegetables and living micro greens (sprouts) containing fresh vibrant green chlorophyll are extremely nutritious ways of creating optimum health and energy.

Just juice: Rosie Huntington-Whiteley has revealed that she loves Chlorella (like those pictured right) green juicesJuicing or blending any raw green vegetable, especially the living leafy varieties, is an effective way of increasing oxygen in the body and helping to build healthy tissues. Oxygen maintains life and is a rejuvenator of all body systems.Green smoothies containing the ingredients seen in Rosie and Miranda’s can be high in vitamin B12, which can help reduce tiredness. The spinach in Rosie’s signature smoothie is high in magnesium, which is found in dark green vegetables and can act as nature’s tranquiliser, helping to keep us de-stressed and relaxed – so it’s no wonder so many busy celebs are trying it!  For instance, a daily serving of the Japanese wholefood Sun Chlorella contains iron content equivalent to nine cups of spinach (270g) and the same B12 content as a 32oz steak – vitamin D in particular is important for winter, as this nutrient is produced by natural sunlight, and long cold winters can cause Brits to become deficient, meaning it’s important to top up where possible.
