I had read all of the press over coconut water and wondered if it was just another trendy gimmick. But after trying it several times now, I am pleased to report back that it actually works! Really. It works. Drink it! It leaves you feeling refreshed and alert. I've even used it at the end of the day, in lieu of a Diet Coke, for a boost of energy. Also, it works almost instantly. You feel better in like a half an hour.
It's not cheap (sometimes running close to $3 a serving), and the taste takes some getting used to, but I am super pleased with the effects. The brand I have been purchasing is Naked (only because I found it on sale). After trying it first over the summer, I'm already on my second case of it (I order it through Amazon.com).
I did some googling:
10 years ago, when the U.N.'s Food and Agriculture Organization (FAO) was granted a patent — the first ever given to a U.N. agency — for bottling coconut water in a way that preserves its nutrients, an FAO official noted that the drink contains the same five electrolytes found in human blood (Gatorade has only two). He called coconut water "the fluid of life." Indeed, in medical emergencies, coconut water has been used intravenously when conventional hydration fluids were not available.
