MINERALS

Minerals are organic compounds that are classified according to the requirements that the organism needs:

  • Macro minerals: a human body needs more than 100mg of macro minerals day. This group is made up of calcium, phosphorus, sulfur, chlorine, sodium, potassium and magnesium.

  • Micro minerals: a person needs to take less than 100mg / day.  Micro minerals, best known as trace minerals include manganese, iron, cobalt, copper, zinc, fluorine and iodine.

  • Main functions in the body

  • They maintain the hardness and rigidity of the bone tissue, teeth, hair and nails, highlighting calcium, phosphorus, magnesium and sulfur.

​

Regulatory function:

  • They are part of biochemical components

  • Participate in the process of maintenance of osmotic pressure

  • Maintain the body acid-base balance

  • Involved in the transport through membrane

 

They intervene in the transmission of the nervous impulse.

The muscular contraction intervenes.

​

 

FOOD SOURCES

Both plant and animal foods provide minerals, even the drinking water of certain areas is rich in some minerals such as iodine, fluoride and copper among others.

 

No food possesses all the minerals in such quantities that it allows its ingestion to satisfy the needs of the individual.

 

It is essential that the diets are mixed and balanced for a correct contribution of the different minerals.

​

 

FOOD REQUIREMENTS

Mineral food requirements vary throughout all stages of life. In general, there is a greater mineral requirement in those stages characterized by development and growth.

MINERALS IN FISH

Fish is a very complete food that apart from providing very good quality protein and healthy fat, such as omega-3 fat, is also a good source of minerals.

The amounts of minerals found in fish are variable depending on the species, but on average you can say that the fish contains:

  • Calcium: the fish that are eaten with spine and some shellfish provide extraordinary amounts of calcium. Calcium helps our bone health and helps prevent osteoporosis.

  • Phosphorus: phosphorus helps along with calcium in the formation of bones and teeth, intervenes in the structure of cell membranes and serves as an energy source in the form of ATP.

  • Potassium: potassium intervenes in the regulation of water balance, in the transmission of nerve impulse and in muscle contraction.

  • Iron: iron is essential for the transport of oxygen in the body.
