British scientist Humphry Davy he was the discoverer of potassium , a essential chemical element whose name comes from the Dutch pottaschen. Davy noticed the existence of potassium in 1807 .

It's about a metal of alkaline type and whitish color that has a substantial presence on the surface of our planet and in the oceans . His symbol is K and its atomic number, 19 .

Potassium is among the lightest and softest metals. Upon contacting the air , it can oxidize at a very accelerated speed, a characteristic that makes its conservation require certain care. Potassium also has violent reactions when it comes into contact with the Water, a link that leads him to detach hydrogen .

The applications of potassium and its derivatives are wide. It can be used, for example, to fertilize land that will be sown. Potassium derivatives are also used in the production of glass and of Photovoltaic cells , In obtaining gunpowder and even in the injections that are applied to those sentenced to death to comply with the capital punishment .

It should be noted that potassium is part of the metabolism of the cells and it is found in a large amount of food that we consume Humans , Like the peaches , the damask , the bananas (also known as bananas ), the avocados and the beets .

The balanced presence of potassium in the body, therefore, is very important to maintain a healthy state. This chemical element intervenes when transmitting the nerve impulses and to regulate muscle contractions, among other functions.

Various foods are recommended to take to give the body the levels of potassium it needs. However, among the most important are the following:
• Peanuts, which have 705 milligrams per 100 grams.
• Soy, which has high levels of potassium and, among many other things, is healthy when it comes to protecting women from what premenstrual syndromes are.
• The banana. The fruit that is considered to contribute a greater amount of the element that concerns us is this, hence it is recommended to take a piece every day in order to cope with problems of cramping or swelling.
• The carrot, which contains 323 milligrams per 100 grams.
• Potatoes, which have 328 grams milligrams per 100 grams and are especially recommended for all those people who have fluid retention problems.
In addition to all these foods, do not forget Brussels sprouts, avocados, strawberries, tomatoes, squash, artichoke or chard ... All of them are very rich in potassium and are recommended to be included in the diet of any person

Athletes are essential to eat products that provide them with the aforementioned potassium and that is how they can benefit from the advantages that it offers: growth of muscle mass, faster recovery after exercise, reduced possibility of suffer cramps, adequate regularization of the cellular functions of the organism ...

Of the amount of potassium we eat, about 90% is absorbed by the small intestine and our organism It eliminates it through sweat and urine. After calcium and phosphorus, potassium is the macromineral that has more presence in the human body; In addition, it has an important relationship with sodium. Approximately 97% is found intracellularly, while the rest extracellularly.

Some of the most important functions of potassium are the following:

* transports oxygen to the brain, with the help of phosphorus;
* collaborates in the disposal of organic waste;
* participates in the normalization of the heart rhythm, together with sodium and calcium;
* it is important to keep the Balance alkaline acid;
* It helps convert glucose into glycogen;
* stimulates neuromuscular activity, together with sodium;
* It is an essential figure for proper growth;
* helps fight fatigue;
* promotes bowel movement and daily deposition;
* participates in the construction of proteins;
* his action Diuretics are necessary for the elimination of liquids;
* collaborates in the regulation of blood pressure.

That said, it is important to note that if the body does not have a normal potassium value, it is possible that certain disorders may occur, including the following:

* constipation;
* heart rhythm disturbance;
* muscle fatigue and weakness;
* pain in joints and bones;
* cramps;
* alteration of blood pressure;
* edema and fluid retention;
* lack of reflexes and mental confusion;
* disorders of increase.

Some of the causes of potassium deficiency are: abuse of laxatives, corticosteroids and diuretics for a long period of time; diabetes mellitus and insipidus; chronic diarrhea; excessive consumption of refined sugar or salt; have suffered from a very serious kidney or heart disease; the practice of low-calorie diets; he stress, both physical and emotional; high doses of carbecillin and penicillin; excessive exposure to the sun's rays; lack of carbohydrates
