The clear liquid found inside unripe coconuts is coconut water. As the coconut matures most of the water turns into flesh. The coconut water tastes yummy (So good!) and in the summer season acts as a coolant in addition to just quenching thirst. It acts like a sports drink - in addition to being low in calories and high in electrolytes like sodium, potassium and magnesium.
Coconut water can be used for the prevention and treatment of dehydration.
Drinking coconut water before exercise can help to increase endurance and exercise performance due to the presence of carbohydrates and electrolytes (which can maintain blood volume and heart health).
The high quantity of potassium helps in reducing blood pressure.
Antioxidants present may help reduce liver damage
Calcium and magnesium in the coconut water help in reducing muscle tension. Magnesium helps in the absorption of calcium into the blood. Calcium in turn helps in muscle contraction and relaxation.
