Information Current scientific research reveals that there are actually very few salt-related health problems. A healthy, active lifestyle demands a sufficient reasonable salt intake. Life is closely dependent upon the presence of sodium. That is why it is more important to study the co-activity of sodium with these other ions, rather than the sodium element alone. Sodium, in the form of sodium chloride, plays an important part in the primary processes of digestion and absorption.
Salt activates the first enzyme in the mouth, salivary amylase.
In the parietal cells of the stomach wall, sodium chloride is used to make hydrochloric acid, a secretion needed for digestion.
