Coconut Water

Bit of a weird one this, but I've been getting cravings recently for coconut water. It's the clear liquid that comes from young coconuts (as opposed to the richer milk found in mature fruit) and is apparently very good for you - fat-free, low in calories and rich in potassium and electrolytes. In fact, it's so damn healthy it's used as an intravenous hydration fluid in some developing countries where medical saline is unavailable (it's true - Wikipedia says so). Drank chilled, like the glass above, it refreshed parts I hitherto were not sure existed.

The can pictured top was bought in the US, but the other day I was delighted to discover you can get cartons of the stuff in the UK too. Vita Coco - 100% pure coconut water - is said to contain 20 times the amount of potassium found in sports drinks, which is why its described as a "super-hydrator". Believe me, you don't need to commit sport to benefit from its rejuvenating properties.

BUY IT? Vita Coco is available from Waitrose, Holland & Barrett and Whole Foods.
