Final answer:
A low-sodium diet helps lower blood pressure by reducing sodium intake and improving fluid balance and kidney function. It is an important component of a comprehensive approach to managing blood pressure.
Step-by-step explanation:
A low-sodium diet helps lower blood pressure by reducing the amount of sodium in the body. When we consume too much sodium, it can cause an increase in blood volume, leading to higher blood pressure. By reducing sodium intake, the body retains less water, which helps to decrease blood volume and lower blood pressure.
For example, when we eat foods high in sodium, such as fast food or processed snacks, the kidneys must work harder to excrete the excess sodium. This can put a strain on the kidneys and increase fluid retention, which in turn raises blood pressure. By following a low-sodium diet, the kidneys have an easier time removing sodium, resulting in better fluid balance and blood pressure control.
It's important to note that a low-sodium diet is often recommended as part of a comprehensive approach to managing blood pressure, along with other lifestyle changes like regular exercise and weight management.
