Health Effects
Chloride and sodium ions, the two major components of salt, are needed by all known living creatures in small quantities. Salt is involved in regulating the water content (fluid balance) of the body. The sodium ion itself is used for electrical signaling in the nervous system.
Salt consumption has increased during modern times and scientists have become aware of the health risks associated with high salt intake, including high blood pressure in sensitive individuals. Therefore, some health authorities have recommended limitations of dietary sodium, although others state the risk is minimal for typical western diets. The United States Department of Health and Human Services recommends that individuals consume no more than 1500–2300 mg of sodium (3750–5750 mg of salt) per day depending on age.
Salt is sometimes used as a health aid, such as a high salt diet being used in the treatment of dysautonomia.

Famous quotes containing the words health and/or effects:
“Criticism is often not a science; it is a craft, requiring more good health than wit, more hard work than talent, more habit than native genius. In the hands of a man who has read widely but lacks judgment, applied to certain subjects it can corrupt both its readers and the writer himself.”
—Jean De La Bruyère (1645–1696)
“to become a pimp
Or deal in fake jewelry or ruin a fine tenor voice
For effects that bring down the house could happen to all
But the best and the worst of us . . .”
—W.H. (Wystan Hugh)
