Good source of several nutrients
Coconuts grow in tropical climates on trees scientifically known as Cocos nucifera, and are botanically considered a fruit.
Coconut water is the liquid found in the center of a young, green coconut. It helps nourish the fruit. As the coconut matures, which takes around 10–12 months, some of the liquid remains while the rest ripens into the solid white flesh known as coconut meat.
Coconut water typically comes from young coconuts about 6–7 months of age, though it’s also found in mature fruit. An average green coconut provides about 1/2–1 cup of coconut water.
Coconut water contains 94% water and very little fat. It should not be confused with coconut milk, which is made by adding water to grated coconut meat. Coconut milk contains about 50% water and is quite high in fat.
One cup (240 ml) contains 60 calories, as well as
- Carbs: 15 grams
- Sugar: 8 grams
- Calcium: 4% of the daily value (DV)
- Magnesium: 4% of the DV
- Phosphorus: 2% of the DV
- Potassium: 15% of the DV
SummaryCoconut water is the liquid found in young coconuts and a natural source of several important minerals.
2. May have antioxidant properties
Free radicals are unstable molecules produced in your cells during metabolism. Their production increases in response to stress or injury.
When there are too many free radicals, your body enters a state of oxidative stress, which can damage your cells and increase disease risk .
Research on animals has shown that coconut water contains antioxidants that may help modify free radicals so they no longer cause harm.
In one 2012 study, insulin-resistant rats on a high fructose diet were treated with coconut water. Free radical activity decreased, as did blood pressure, triglycerides, and insulin levels.
Another study from 2014 found that damaged rat livers showed significant improvement in oxidative stress when treated with coconut water compared with livers that received no treatment
A third study from 2016 highlighted the benefits of coconut water extract on rats fed a high fat diet. Not only did the coconut water help decrease cholesterol markers, but it also showed “antioxidant potency .”
While these studies are interesting, it’s important to note that no studies involving humans and the antioxidant power of coconut water have been done to date, and each of the animal studies used different dosages and parameters.
3. May help lower blood sugar for people living with diabetes
Research has shown that coconut water can lower blood sugar levels and improve other health markers in animals with diabetes.
In a study from 2015, rats with diabetes that were treated with coconut water maintained better blood sugar levels than the control group. The same study also found that the rats given coconut water had lower levels of hemoglobin A1c, indicating better long-term blood sugar control.
A more recent study from 2021 involving rats with diabetes also found that that coconut water reduced blood glucose
More studies are needed to confirm these effects in humans.
However, another added blood sugar benefit of coconut water is that it’s a good source of magnesium, which may increase insulin sensitivity and decrease blood sugar levels in people with type 2 diabetes and prediabetes.
With all this in mind, it’s important to note that coconut water contains carbs (which are broken down into sugars in the body), so if you are living with diabetes or prediabetes, talk with your doctor or a dietitian before adding it to yours.
4. May help prevent kidney stones
Drinking enough fluids is important for kidney stone prevention.
Although plain water is a good choice, two small studies suggest that coconut water might be even better.
Kidney stones are created when calcium, oxalate, and other compounds combine to form crystals in your urine. These crystals can then form tiny stones. While some people are more susceptible than others, kidney stones affect about 12% of the world’s population .
In a 2013 study in rats with kidney stones, coconut water prevented crystals from sticking to the kidneys and other parts of the urinary tract. It also reduced the number of crystals formed in the urine.
In a study from 2018 that involved eight people, researchers found that coconut water increased the urination of potassium, chloride, and citrate in individuals without kidney stones, meaning coconut water might help flush out the system and keep the likelihood of stones low
Because one study involved animals and the other is so small, much more research needs to be done concerning the benefits of coconut water in reducing the possibility of kidney
5. May support heart health
Drinking coconut water may help reduce heart disease risk
In an older study from 2008, researchers fed rats a diet rich in fats and cholesterol. They also fed one group high doses of coconut water (4 ml per 100 grams of body weight).
After 45 days, the coconut water group had a reduction in cholesterol and triglyceride levels similar to the effects of a statin drug used to lower cholesterol
Keep in mind that this was a very high dose. In human terms, it would be equivalent to a 150-pound (68-kg) person consuming 91 ounces (2.7 liters) of coconut water per day.
A 2005 study suggests that coconut water may also be beneficial for lowering blood pressure in individuals living with high blood pressure, but more research needs to be done in that area
One of the reasons coconut water may be connected to lowered blood pressure is its impressive potassium content (500mg of potassium in 8 ounces). Potassium has been shown to lower blood pressure in people with high or normal blood pressure
6. Beneficial after prolonged exercise
Coconut water may be the perfect beverage for restoring hydration and replenishing electrolytes lost during exercise.
Electrolytes
are minerals that play several important roles in your body, including
maintaining proper fluid balance. A few vital electrolytes include
potassium, magnesium, sodium, and calcium (
Because coconut water contains electrolytes like potassium and magnesium, several studies have found that it may be more beneficial than water for rehydration after exercise
