Action:
Sodium is involved in various processes in the body, such as:
- Regulation of fluid balance: helps maintain the right amount of water in the body, both inside and outside the cells.
- Maintaining blood pressure: affects blood pressure because it regulates the volume of fluids in the body.
- Transmission of nerve impulses: it is essential for the conduction of nerve impulses, which are responsible for communication between nerve cells.
- Muscle work: participates in the processes of muscle contraction and relaxation.
Importance for the diet:
Sodium is an essential component of the diet, as it is responsible for maintaining fluid balance in the body, the proper functioning of the nervous system and muscles. Too little sodium intake can lead to electrolyte imbalances and other health problems. However, excessive sodium intake can be harmful, especially for people with hypertension, heart disease or kidney failure. Excess sodium can lead to water retention, increased blood pressure and strain on the kidneys.
