What type of diet is typically recommended for patients with hypertension?

A low-sodium diet is recommended for patients with hypertension because sodium can cause the body to retain water, which increases blood volume and, consequently, blood pressure. When sodium intake is reduced, it can help decrease the volume of fluid in the blood vessels, leading to lower blood pressure levels.

Research and medical guidelines emphasize the importance of managing sodium intake as part of a comprehensive approach to controlling hypertension. This diet typically involves choosing fresh, whole foods while avoiding processed foods, which often contain high levels of sodium. By focusing on a low-sodium diet, patients can more effectively manage their blood pressure and reduce their risk for cardiovascular complications.

In contrast, high-fiber, high-protein, or ketogenic diets may have their benefits in different contexts or health conditions, but they are not specifically geared towards managing hypertension as directly as reducing sodium intake.
