Coconut water, in case you haven't heard, is the new "it" beverage. Sales are skyrocketing. It's promoted as "super hydrating" and marketed as both a sports drink and a casual beverage. Personally, I find the name a bit confusing. Just what is coconut water? I looked into it and here's what I came up with.

Is it water or juice?

Coconut water is not water with coconut flavor added. It's the fluid inside the coconut, not to be confused with coconut milk, which is an emulsion of coconut water and fresh grated coconut. So coconut water is a type of juice.

Compared to other juices, coconut water has similar or fewer carbohydrates and calories in an 8-ounce serving. However, coconut water has more potassium, sodium, magnesium and calcium than most juices.

Is it a sports drink?

The answer is probably no, at least for vigorous exercise — when you're working hard and really sweating for longer than an hour. In that case, coconut water falls short in terms of carbohydrates and protein, according to sports nutrition standards. Both are essential to recovery and replenishing your muscles.

Is it a good casual beverage?

Possibly. Here are a few things to consider. Do you need the 45-60 calories an 8-ounce serving of coconut water provides? If these calories put you over your daily calorie needs, you could easily gain 5-6 pounds in a year. If you aren't active enough to fend off the pounds, plain water might be a better bet.

One of coconut water's claims to fame is its high potassium. Americans usually fall short of their daily requirement of potassium, mainly because they don't eat enough fruits and veggies. However, coconut water also contains sodium. Just how much depends on the brand. That might be a concern if you, like most Americans, already have too much sodium in your diet.

If you've tried coconut water, what do you think? Did you feel super hydrated and replenished, as fans claim? Will you continue to drink it?

To your health,

Katherine

    I love coconut water!!! It was my saving grace when I was in Goa, India getting another certification for yoga. My "coconut water" guy chucked them for me from the tree in his front yard and would freeze it for me in my large water bottle. It was average 93 degrees each day and I drank regular water too which we had to pay for to get large amounts that were CLEAN. I still drink it daily here in the states and practice a heated style of yoga and it's been one of the best things to keep me hydrated. I'm not worried about any weight gain. I stay active enough, and I don't drink alcohol, coffee, or soda, rarely a juice unless I juice it myself.

    I received a Kidney Transplant last year and one thing I was told to make sure I drink plenty of fluids. I try to drink water, but cannot seem to keep up with the amount I should drink. Then I found Coconut water and loved the taste. I feel hydrated and I eat everything low sodium and adding this to my diet has helped me a lot. I found a brand ZICO at Costco and I travel with it where ever I go. I have absolutely no desire to drink Soda or Juices. I love my Coconut water!!

    The idea that a 65cal drink would cause 5 pounds of weight. The human body can easily handle the calories without gaining weight. And if you are drinking more coconut water you are probably drinking less soda or fruit juice.

    I live in the tropics and drink about 48oz of fresh from the coconut, it's water. It is not store bought. We have a grove of coconut palms. I start every morning with a large glass and feel rehydrated, rejuvenized and not to mention love the taste. But I do worry if the calorie intake is too much. I have been known to drink the entire pitcher in a day, especially if we have been out on the water. The only effects I have found have been positive. It helps with regularity, I suffer with indigestion and it helps with that too. When we are traveling and I do not have my daily dose, I feel the difference. That is my 2cents worth of the wonderful coconut water.

    I drink several liters of water a day anyway, but coconut water is just soooo... tasty! I like that it's not from concentrate, unlike so many other juices. Can't say I drink it daily, but treat myself to it often.

    I have been drinking coconut water for about 2 years and i drink it when i want to and when i remind myself. I play competitive sports like ice hockey and soccer and i find that its similar to taking a vitamin but in a drink form. Coconut water is SUPER hydrating and refreshening after you get past the shocking taste that comes with the naturalness of it. I am 100% pro coconut water but dont let it replace water because it does have things like carbs.

    I LOVE coconut water. It has to be flavored (chocolate and mango are the best) so that adds more sugar than is necessary so I try not to drink it too often. I think that it helps to hydrate you more than other beverages. I agree with Tim below that if you drank a little too much the night before, coconut water is a dream in the morning :)

    I used to suffered from severe legs cramps at night. Sometimes when exercising I would get a terrible leg cramp. After I was recomended to drink coconut water my cramps are gone. I drink only a quater of a cup after exercising.

    Question: Most of what I've seen published about the value of coconut water relates to fresh water obtained first-hand from a fresh coconut - no intermediaries. Since exposure to oxygen rapidly depletes coconut water of its valuable components, is the bottled stuff any good at all, or is it just another attempt of the food industry to capitalize on the latest health fad? The bottled stuff is inordinately expensive, and to bottle it, you have to expose it to oxygen (and to light, which also has a tendency to destroy certain vitamins, etc; and presumably to heat as well). Is there anything of value left when all that is done? BTW, this question comes from a resident of Chicago, where it's pretty hard to come by fresh coconuts with any regularity. ^_^

    I love coconut water as it always hydrates me when I am parched. It works wonders if you have a hangover fyi!

    It is a very refreshing break during hot yoga, as others have mentioned. I dilute it with 1 part tap water to 1 part coconut water, mixed in a thermos, to cut the sweetness and reduce the calorie load.

    I think coconut is one of the best... its water is as beneficient as ....... :)

    I'm surprised no one has mentioned that the calories and carbs in coconut is not stored in the body as fat but goes straight to energy, this according to researchers on the "Dr. Oz" show.

    Drink from the naturally packed green coconut and feel the difference. Packaging damages most nutritions in most foods. Drinking the packaged coconut water does not give the actual effect. No need to balance the minerals, no fear of high salt level, no restriction for any disease, sufficient energy content to refresh you, no need to sterilize before use. Don't waste on packaging as the green coconut comes without any expiry date. Promote it to reduce your carbon footprint.

    I live in India. The coconut is pretty commonly used in variety of foods here and the "coconut water" is called as "tender coconut water" over here. It is very popular especially during the summer season here and you can drink it almost at any roadside place where they're selling it freshly from the coconut itself. The water is highly sterile and during the WW2 wars long back, British troops who were injured and were short on saline / glucose, were directly injected with coconut water :) Regards, Murthy.

    I am surprised thara you didn't talk about the diuretic properties of coconut water. This is one of the main reasons doctor's recommend it here in DR; mainly fresh Regards rita

    I like coconut water, but I haven't yet tried the packaged variety. I'm diabetic, and I take a tablespoon of coconut oil a day for my blood sugar. It has come down 10-15% so far. Very happy.

    As a raw nutritionist, research has shown that coconut water is most like our blood plasma. In one year of consumption of coconut water, my platelets have increased from 140,000 to 218,000. This is pretty remarkable to me. I believe that it would be important for cancer patients who have low platelet counts to have this infomation. It might help them!

    Living in the Caribbean, we have been drinking coconut water for our entire lives. But we drink the real thing, straight from the nut itself, not a package. It is great as a casual beverage, wonderful chaser, and a much better option than all those carbonated drinks out there. I won't stop drinking it.

    I do notice a difference, esp. at night with fewer leg cramps which would wake me up. Low Potassium levels are known to cause leg cramps, along with low magnesium and calcium. It does have more potassium than 3 bananas. You need to get use to the taste, so I am selective on the brand.

    I live in Costa Rica where coconut water is a popular beverage. I sustained a mild concussion in an accident and had some frontal memory problems. Coconut water was recommended and I had an almost instant result. The Costa Ricans also use it as a diuretic.

    as Jane has mentioned, coconut oil is getting a lot of credit for help with memory problems. a florida doctor has researched and is giving to her husband with improved test results. my wife is now taking and uses in cooking, especially omelets. would like your opinion on this subject. tks.
