Water
Water is a nutrient which makes up 65-75% of our body. This quantity should be kept constant, as water allows the transport of minerals, it helps to maintain thermal balance, and it makes possible the digestion, the absorption and transport of nutrients and the elimination of waste substances. Although we ingest a large amount of water through food, we also need to drink it directly, in order to satisfy the most secure and effective regulator of our body: the thirst.
