Health claims for coconut water: water works really well
The big surprise in Michael Moss’s tough look at health claims on coconut water in today’s New York Times—worth looking at online for the terrific video—is this:
One Last Comparison
These days, coconut water’s big rival may be plain old water. How do they compare? Scientists are still wrestling with the question, and while their findings vary, water is starting to look just fine for most people. A 2012 study (funded by Vita Coco) in the Journal of the International Society of Sports Nutrition found that neither coconut water nor sports drinks were better than water in hydrating young men after hourlong workouts.
Really? An industry-funded study that comes to a conclusion against the interest of the funder?
This requires a look at the original paper.
So a round of applause please for the authors who did this funded study, “Comparison of coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men,” and nevertheless came to this conclusion:
Our data indicate that both coconut water (natural, concentrated and not from concentrate) and bottled water provide similar rehydrating effects as compared to a carbohydrate-electrolyte sports drink. Moreover, none of the beverages impacted treadmill exercise performance differently during the rehydration period.
Lest there be any ambiguity about what this means, their data clearly show that VitaCoco, a sports drink (not named but I’d bet on Gatorade), and coconut water from concentrate all rehydrated men who spent 60 minutes on a treadmill to the same extent.
In other words: for rehydration, water works just as well as coconut water or sports drinks. No surprise, really.
VitaCoco must be disappointed, but it still has one thing going for it: coconut water tastes really good.
