It seemed to me I'd heard once that, in a pinch, one could use coconut water as IV fluid. I opened up Google and started typing "use coconut water" and sure enough, an auto-fill option popped up that read: "can you use coconut water as IV fluid". Apparently, the answer to that unpunctuated question is... "kinda."
There are actually multiple anecdotal reports of doctors successfully administering coconut water intravenously in cases of extreme dehydration when traditional IV fluids were absent. For some reason, I'm thinking these were cases of final desperation, rather than calculated medical maneuvers, but hey, I'm no doctor. I guess the bottom line here is that coconut water is just really darn good at providing hydration to the human body.
Now I'm guessing the addition of pineapple juice is a big "no-no" when attempting to inject the liquid directly into a vein, but when ingested orally, it makes coconut water a moderately enjoyable beverage, as is the case here. And when I say "moderately enjoyable," I mean that as a relative term. I mean that people who just barely tolerate the taste of coconut water (like me) will tolerate it with significantly less of a grimace on their face now that it's available with pineapple juice mixed in—unless, of course, said person is also not a fan of pineapple juice.
Sonia generally enjoys regular coconut water and thinks this mix is even better. "It's like a really watered down pina colada," she says. I won't argue with that, though I'd emphasize the "really watered down" part. It's about $4 for four small cans, which isn't cheap. Sonia would like to point out, though, that while sick with the flu, she used this beverage to stay well-hydrated. Not only that, but there's a good bit of vitamin C in there, too. So if you think of it as medicine, the price point seems more reasonable.
Sonia gives this coconut water 4.5 stars. I give it 3.
Bottom line: 7.5 out of 10.
