Coconut water is one of the hottest
food trends. Is it all hype, or is coconut water worth trying?
Coconut water is the thin liquid found
inside young green coconuts. A freshly opened young coconut is a
refreshing drink when you’re under the hot tropical sun. If you’re
far away from the tropics, pasteurized coconut water can be found at
your local grocery or health food store.
Pure coconut water has no cholesterol,
is very low in fat and calories, and naturally contains the essential
electrolytes potassium, sodium, phosphorus, magnesium and calcium.
An 11 ounce serving of coconut water
has about 60 calories and 700 milligrams of potassium, more than a
banana. Potassium helps regulate fluid and mineral balance, controls
normal blood pressure and helps your muscles contract. Coconut water
is considered isotonic, which means that the electrolyte balance is
similar to our blood. Fresh coconut water
was used for emergency plasma transfusions during World War II.
A Substitute for Sports Drinks?
Many consider coconut water a natural
sports drink. Traditional sports drinks are formulated with the
right balance of electrolytes and carbohydrates for athletes and
others who exercise vigorously. Sports drinks are recommended if you
exercise 60 minutes or longer or when you’re exercising in extreme
heat. Water is effective for light to moderate exercise. Some experts
say that coconut water doesn’t contain enough sodium or
carbohydrates to effectively replace sweat or fuel energy during
strenuous exercise. Since sodium is the primary electrolyte that’s
lost in sweat, an adequate amount is needed for rehydration. However,
there are a few studies that have tested coconut water and found it
to rehydrate just as well as traditional sports drinks. Coconut water
definitely shows potential, but there needs to be further scientific
research before any conclusions are made.
The Jury is Still Out
Coconut water can be pricey, but it’s
a healthy replacement for sugary, high calorie drinks and may help
rehydrate during illness and after exercise. More scientific research
is needed to fully recommend using it during and after exercise,
though. I have encountered several athletes who believe coconut
water works just as well or better than sports drinks. They say
coconut water doesn’t cause nausea or bloating and replenishes
their bodies efficiently after exercise. People with kidney disease
should discuss using coconut with their doctor or dietitian first,
since the potassium content is high. Just a note: flavored coconut
water may contain added sugar and be higher in calories.
- Make your oatmeal with coconut water
for an added boost of potassium.
- Add cold coconut water to your fruit
smoothies after a workout.
- Freeze a tetra pack of coconut water
for 30 minutes for a refreshing slush.
- Use coconut water instead of regular
water to make rice. It will boost nutrients and add a little flavor.
