Eight ounces of coconut water has 46 calories, 9 grams of carbohydrates, 250 mg of sodium, 200-500 mg of potassium, 60 mg of magnesium, 45 mg of phosphorus, and 2 grams of protein. The electrolyte content is more than double that of traditional sports drinks with about half of the carbohydrates. (Potassium is an essential macromineral in human nutrition; it is the major cation (positive ion) inside cells, and it is important in maintaining fluid and electrolyte balance in the body.)
According to researchers, individuals with high blood pressure usually have low potassium levels. Therefore, drinking coconut water on a regular basis can be quite effective at regulating blood pressure.
Coconut milk (made from the meat of the coconut) has 500-600 calories, and coconut water(liquid inside) contains about 50 calories.
A few studies have shown coconut water to have cytokinins which are beneficial for anti-aging, anti-carcinogenic and anti-thrombotic effects. The American Institute for Cancer Research says that some of the compounds in coconut water, such as selenium, have antioxidant properties and fight cancer in the lab(many common fruits and vegetables are packed with these compounds). Several animal studies suggest coconut water can lower cholesterol and blood pressure, but this research is too preliminary to make any claims yet.
