Water, an irreplaceable element
Water is the most important substance for human survival. Under extreme conditions, human beings can last several weeks without eating, but no more than three or four days without drinking. In addition, an adult’s body is composed of 65-70% water, while an infant’s body is 75-80% water. This important element must be continually reintroduced into the body to ensure health and wellbeing. Due to its importance in maintaining good health, particular attention must be given to the properties of the water that we drink every day.
The choice should take into account the water’s organoleptic characteristics – the label offers a complete overview of this information. Specifically, it is important to know the quantity of mineral residues present in the water.
CLASSIFICATION OF MINERAL WATERS
VERY LOW MINERAL CONTENT Fixed residue of less than 50 mg/l
Due to the very low concentration of mineral salts, these favour diuresis and facilitate the elimination of small kidney stones. They are indicated for people on low-sodium diets and children.
LOW MINERAL CONTENT Fixed residue of 50 – 500 mg/l
The low concentration of mineral salts makes these excellent for everyday consumption. They are indicated for people on low-sodium diets since they have a diuretic effect.
MODERATE MINERAL CONTENT Fixed residue of 500 – 1500 mg/l
These are indicated for people with a deficiency in certain minerals and, thanks to the bicarbonate content, people with digestive problems.
RICH IN MINERAL SALTS Fixed residue greater than 1500 mg/l
Very rich in salts, they are generally used for curative purposes. As such, it is recommended that they be consumed only on the advice of a physician.
