Sodium intake refers to the total amount of sodium a person consumes through food and beverages. Sodium is a mineral that is essential for many body functions, primarily found in table salt and processed foods. Monitoring sodium intake is important for maintaining overall health, as excessive sodium can lead to health issues, particularly concerning the kidneys and cardiovascular system.
Sodium matters for health because it helps regulate blood pressure and supports fluid balance in the body. However, too much sodium can cause the body to retain water, leading to increased blood pressure and putting extra strain on the kidneys. Chronic high sodium intake is linked to conditions like hypertension and heart disease, making it essential to keep sodium levels within recommended limits.
In the body, sodium plays several key roles, including helping nerves send signals and muscles contract properly. It works closely with potassium, another important mineral, to maintain fluid balance and support cellular functions. The kidneys filter excess sodium from the blood, which is then excreted in urine. However, high sodium intake can overwhelm the kidneys and impair their function over time.
It is important to be aware of sodium intake levels, especially for individuals with existing health conditions or those at risk for kidney disease. Reducing sodium intake can be beneficial for overall health and help prevent complications related to high blood pressure and kidney function.
