Once upon a time there was juice. Orange, or apple if you were lucky. But these days, we want our drinks to do more than just taste nice and go with our toast - and while smoothies and hand-prepared concoctions with wheatgrass shots have been stealing the limelight, juice is fighting back.

First up is a new drink proven to benefit blood circulation, thanks to a tomato extract, which thankfully is completely tasteless.

Sirco, which comes in Pomegranate & Orange and Blueberry & Apple, is 100% pure fruit juice, plus the tomato extract, which helps to keep your heart healthy as research has found it helps the blood to flow more smoothly and keeps the arteries clearer. You could always stick to tomato juice, but you'd need to drink more to get the same effects.

One 250ml glass a day is all you need, and a litre costs around 99p, from Waitrose and Holland & Barrett.

Or how about mangosteen juice? Jennifer Aniston and Kate Moss are apparently fans of the exotic fruit's juice, containing antioxidants which promise to do everything from sorting your skin to protecting the heart and even helping prevent cancer, while it's also traditionally antibacterial, antiviral, anti-inflammatory and anti-fungal!

Nope, says dietitian Lyndel Costain. 'If it sounds too good to be true, then it is! It is a fruit, so contains antioxidants like all fruit, but it's not actually super-nutritious in terms of vitamins and minerals. It has been used in traditional remedies in South East Asia, but there's a lack of hard evidence.'
