If you find the unnatural color of many sports drinks unappealing, you might be interested in trying coconut water. They don't call it "nature's sports drink" for nothing. A cup of coconut water contains about 600 milligrams of potassium (that's more than a banana), as well as some calcium, magnesium, sodium, and sugar.
The liquid found inside young green coconuts is thin, almost clear, and can have a slight almond flavor. Coconut water should not be confused with coconut milk. Coconut water contains no saturated fat and has only 45 calories per cup to coconut milk's 552.
The coolest thing about coconut water is that it has the same electrolyte balance as blood. Dubbed the "fluid of life," it was used as a substitute for intravenous plasma during World War II.
You can cut the top off a young coconut with a meat cleaver and drink the juice. Or you can find bottled coconut water, but it just might be mixed with sweetener. Drink up!
