Thus far, I’ve reviewed the proof on coconut oil and coconut milk that counsel neither is nice for you. However what about coconut water? After I first realized about athletes utilizing coconut water as a pure Gatorade, I did a medical literature seek for athletes and coconut, and solely got here up with this: a examine of “canine athletes.” Seems feeding drug- or bomb-sniffing canines coconut oil can generally wipe out their means to odor in any respect. However, what about coconut water and human athletes?

Research on coconut water as an electrolyte-replacement beverage date again a long time, when coconut water was in comparison with different drinks, and located to be “extra appropriate.” However, the opposite drinks they in contrast it to have been like Pepsi, Coke, Sprite and 7Up. You don’t actually know—till you place it to the take a look at. It was discovered to assist in circumstances of delicate dehydration, as a result of childhood diarrhea, regardless of having an unbalanced “electrolyte composition”—by which they meant the sodium/potassium ratio was off.

Coconut water has a lot potassium that individuals with kidney illness can run into “life-threatening hyperkalemia” (an excessive amount of potassium within the blood) in the event that they drink like two quarts of coconut water and don’t have regular kidney operate—which might in any other case simply flush the surplus away. Individuals could not understand coconut water has a lot potassium. So, even when your physician warned you about staying away from high-potassium meals, you might not understand, and will run into issues. Even one quart a day could also be an excessive amount of for somebody whose kidneys have been compromised by diabetes, for instance. Cream of tartar is similar sort of factor. Individuals don’t understand it’s like 20% pure potassium. So, after they hearken to web sites claiming it’s some “‘pure’ treatment,” even younger folks with wholesome kidneys can run into issues in the event that they take spoonfuls of the stuff—with cream of tartar overdose deaths relationship again to the 1800s.

However, what about “rehydration after train with contemporary younger coconut water”? Sure, it might probably assist substitute fluid loss from diarrhea; what about fluid loss from heavy train? We didn’t know, till this examine. 90 minutes at about 90 levels Fahrenheit till they misplaced as much as 3% of their physique weight. Then, researchers had them drink coconut water, versus a sports activities beverage, versus simply plain water—and, no important distinction in rehydration for any of them. Subsequent examine findings have been extra blended. Some confirmed a sports activities drink beat out water for hydration, however coconut water didn’t. Or, they each beat out water, however not one another. The explanation athletes care about rehydration is that they care about efficiency. However, there had by no means been any research on not simply “measures of hydration,” however on “bodily efficiency”—till this examine.

They examined water, versus coconut water, versus coconut water from focus, versus a typical sports activities drink. Then, they caught folks on a treadmill and timed how lengthy they may go earlier than they collapsed. And, they found “no important distinction” between any of them. Plain water did simply in addition to coconut water—in truth, even higher, since these consuming the coconut water felt “extra bloated,” with upset tummies. Now, this was all finished at room temperature, about 70 levels. What about as an alternative at over 90 levels Fahrenheit? Then, the coconut water did appear to beat out water. However, “time to exhaustion” isn‘t the identical as efficiency. That’s one thing that’s routinely utilized in laboratory research. However, doing one thing like “a time trial take a look at” would truly measure velocity and efficiency. However, there’s by no means been a head-to-head water versus coconut water-time trial—till now.

Consuming coconut water, bikers make it 10k in 971 seconds, and on plain water, about 5 seconds quicker—in different phrases, no important distinction. The primary examine on the usage of coconut water throughout train, and it appears prefer it’s “no extra useful than plain water.”

How’s the coconut water trade going to spin this? They have been those that funded the examine that discovered no distinction between plain water, coconut water, and sports activities drinks. So, did the authors conclude VitaCoco isn’t any higher than water? No, they mentioned coconut water…is simply nearly as good as sports activities drinks! That’s a discovering athletes and coaches will “possible [find] of most significance”—failing to notice that not solely did plain water do exactly as nicely, it did higher, as a result of there was twice as a lot abdomen upset within the coconut-water teams. However wait; if all of the drinks did equally nicely, then this isn’t only a refutation of any particular properties to coconut water, however the sports activities drinks as nicely. In the event that they do no higher than water, are sports activities drinks only a waste of cash? We’ll discover out, subsequent.
