Contains several nutrients
The liquid present in the middle of a young, green coconut is called coconut water. It aids fruit nutrition. The coconut matures over the course of around 10 to 12 months, during which time some of the liquid is retained and the remainder turns into the solid, white meat known as coconut meat.
Though it can sometimes be found in mature fruit, coconut water is more frequently found in young coconuts that are around 6-7 months old. A typical green coconut yields between 1/2 and 1 cup of coconut water.
Coconut water contains 94% water and very little fat. Do not confuse it with coconut milk, which is made by mixing water with grated coconut meat. Unlike coconut water, coconut milk contains about 50% water and is quite high in fat.
