Coconut Water

One way to help prevent dehydration, whether you're braving triple digits for errands or trying to find a shady path to run, is to stock up on coconut water.   I first discovered it doing Bikram Yoga a few years ago, and I got to say its a pretty refreshing tipple served chilled after a hard workout or even if you are suffering the dehyrating effects of a night out!  I also give a small glass to my girls if they have suffered a bout of diarrhoea or tummy upset as it re-hydrates quickly due to the electrolyte content.

• Why drink it?  Coconut water contains many essential electrolytes, including a whopping amount of potassium, which rehydrate you quickly — perfect for a postworkout at any time, but especially important when the heat rises.
• Mix it up. Add coconut water to smoothies, use flavored coconut water to make ice lollies (Vita Coco's acai and pomegranate flavour is a goodie!

Available in Tesco's and most Health Food stores.  Another good brand is Zicco, if you can't find Vita Coco.
