At the heart of the unripe, green-shelled coconut lies water from a veritable fountain of youth. Not to be confused with coconut milk, this clear beverage is loaded with potassium, magnesium, calcium, and electrolytes. It is also low in sugar and 99% fat free – sipping just one of these slightly sweet treats is enough to noticeably elevate mood; two servings hydrates the body after a long workout at the gym, and three can annihilate even the most persistent hangover.

From the unspoiled shores of Costa Rica and Panama to the idyllic beaches of India and Africa, the water from this exceptional nut has long been prescribed as a holistic treatment for headaches, fevers, obesity, kidney stones and even the pains of pregnancy. In fact, the sterile substance is so metabolically complete that it can be infused directly into the human bloodstream instead of saline – a practice often utilised in emergency situations during the Vietnam War.

As an added bonus, coconut water also promotes weight loss – and at 45 calories per serving, even the most dedicated dieter can guzzle them down guilt-free. After soaking up the health benefits of this invigorating drink, don’t forget to slice open the shell and devour the milky fruit inside.
