The English chemist Humphry Davy (1778 -1829 ) was the discoverer of sodium and other substances that he managed to isolate at the beginning of century XVIII through the electrolysis . The term sodium comes from Italian soda and from Latin sodium.

Sodium is the chemical element whose atomic number is 11 . It's about a metal of great presence on our planet, which is soft and white or silver. It is usually found as Salt .

Among the characteristics of sodium, we can mention that when in contact with oxygen, rust and that it is a metal of great reactive power. In nature, sodium is not free: it can be found, for example, in the sea, although in an ionic form. Sodium and Water they form a hydroxide .

Due to its importance for metabolic processes, sodium is considered an indispensable element for life. This metal helps to transmit nerve impulses, helps the membranes absorb nutrients and encourages the contraction of the muscles .

There are a lot of compounds that include sodium and that have an extended use in everyday life. One of them is the sodium chloride (table salt), which is used to season food. He sodium bicarbonate (elevates masses and other gastronomic preparations) and the sodium triphosphate (used for soap production) are other commonly used compounds.

In the field of nutrition, by some of the indications we have raised, sodium is a primary element. Specifically, it is considered to exercise such important functions as these:
-It is involved in the process of contraction of the muscles, to make it ideal.
-Proceed to maintain what is the potential of the membrane that exerts a primary task in the transport of nutrients in the body, cardiac function or even the development of nerve impulses.

Precisely because of these and other actions carried out by sodium, nutritionists and doctors establish that we all have to have a healthy, complete and balanced diet where it is present at levels that are beneficial. Therefore, in addition to salt, they establish the need to take other foods that also have it in generous quantities. We are referring, for example, to dairy products, shellfish, certain vegetables and even meats.

It should also be taken into account that people who have sodium deficiency are going to have to face serious health problems, such as is known as hyponatremia, which is identified by the fact that the person in question has a blood sodium concentration that is less than 135 mmol / l, which is normal. This situation seriously endangers the health of that because it causes dehydration, nausea, severe headaches, fainting, palpitations, vomiting, muscle cramps ...

It should be noted that the symbol of sodium is Na , which comes natrĭum (Latin denomination of soda or soda).
