Which dietary component should be limited to manage high blood pressure?

Limiting sodium intake is crucial for managing high blood pressure. Sodium can cause the body to retain water, which increases blood volume and, consequently, blood pressure. High sodium levels are commonly associated with processed foods, canned goods, and certain condiments, making it important for individuals with hypertension to be conscious of their sodium consumption.

A diet that is lower in sodium can help reduce blood pressure and improve overall cardiovascular health. The Dietary Approaches to Stop Hypertension (DASH) diet, for example, emphasizes the reduction of sodium while focusing on fruits, vegetables, whole grains, and lean proteins, which can help manage blood pressure effectively.

In contrast, while proteins, carbohydrates, and fats are essential components of a balanced diet, they do not have the same direct effect on blood pressure that sodium does. Therefore, focusing on limiting sodium is a key strategy in the management of hypertension.
