Chlorine, along with potassium (K) and sodium (Na), is one of the three nutrients that humans need in large quantities.
In animals and humans, chlorine ions are involved in maintaining osmotic equilibrium; chloride ion has an optimal radius for penetrating the cell membrane. This explains its joint participation with sodium and potassium ions in the creation of constant osmotic pressure and regulation of water-salt metabolism. The body contains up to 1 kilogram of chlorine and it is concentrated mainly in the skin.
Chlorine is often added to purify the water to avoid contracting certain diseases, such as typhoid fever or hepatitis. When the water is boiled, the chlorine evaporates, which improves the taste of the water.
Chlorine rich foods
Indicated approximate availability in 100 g of product
Chlorine daily requirement
The daily requirement for chlorine is 4-7 grams. The upper permissible level of consumption of Chlorides has not been established.
Chlorine is well excreted from the body with sweat and urine in almost the same amount as consumed.
Useful properties of chlorine and its effect on the body
Chlorine is actively involved in maintaining and regulating water balance in the body. It is necessary for normal nervous and muscular activity, promotes digestion, helps to remove substances clogging the body, takes part in cleansing the liver from fat, and is required for the normal functioning of the brain.
Chlorine in excess helps to retain water in the body.
Interaction with other essential elements
Together with sodium (Na) and potassium (K), it regulates the acid-base and water balance of the body.
Chlorine deficiency signs
- muscle weakness;
- dry mouth;
- loss of appetite.
The advanced chlorine deficiency in the body is accompanied by:
- lowering blood pressure;
- increased heart rate;
- loss of consciousness.
Signs of excess are very rare.
Factors affecting the chlorine content of foods
When salt is added during cooking to any food or dish, the chlorine content there increases. Often in the above tables of certain foods (for example, bread or cheese), the content of a large amount of chlorine there arises due to the addition of salt to them.
Why chlorine deficiency occurs
There is practically no chlorine deficiency, because its content is quite high in many dishes and water used.
