The element chlorine (Cl) is a poisonous gas. When chlorine is reacted with sodium or hydrogen, however, it gives rise to the negative chloride ion. Chloride mineral is required in the diet. It is the major anion present outside the cells and id closely related to the sodium.
These include table salt, soy sauce along with
- Animal sources: These include milks, eggs, moderate amount of meat and cheese
- Plant Sources: Large amount in processed foods, cucumber, coconut, banana, and pineapple are its plant sources.
- Chloride is the major anion of the extracellular fluids, where it occurs mostly in association with sodium.
- Chloride can move freely
- The consuming of ordinary foods and beverages can restore chloride balance across membranes and so also associates with potassium inside cells.
- Like sodium, chloride maintains fluid and electrolyte balance.
- In the stomach, the chloride ion is part of hydrochloric acid, which maintains the strong acidity of the gastric juice. One of the most serious consequences of vomiting is the loss of this acid from the stomach, which upsets the acid-base balance. Such imbalances are commonly seen in bulimia nervosa.
Recommendation and Intakes
Chloride is abundant in foods (especially processed foods) as part of sodium chloride and other salts. A recommendation intake has not been established for chloride; instead a minimum requirement for adults has been estimated.
Diets rarely lack chloride. Chloride losses may occur in conditions such as heavy sweating, chronic diarrhea, and vomiting. The only known cause of high blood chloride concentrations is dehydration due to water deficiency. In both cases, consuming ordinary foods and beverages can restore chloride balance.
In case of its toxicity no such ill effects are seen except vomiting occurs.
