What is an important dietary recommendation for managing hypertension in older adults?

Reduced sodium intake is an essential dietary recommendation for managing hypertension in older adults due to its direct impact on blood pressure. Sodium contributes to fluid retention, which can elevate blood pressure levels. Reducing sodium in the diet helps decrease the volume of fluid in the bloodstream, ultimately lowering blood pressure and decreasing the risk of heart disease and stroke, which are critical concerns for older adults.

The sodium-restricted dietary approach, such as the DASH (Dietary Approaches to Stop Hypertension) diet, emphasizes whole foods, including fruits, vegetables, whole grains, and low-fat dairy products, while minimizing processed foods that are often high in sodium. This shift not only helps in managing hypertension but also supports overall cardiovascular health, which is particularly vital for older populations.

In contrast, increased protein intake could potentially be beneficial depending on the individual's overall health status and dietary needs, but it does not have the same direct effect on blood pressure as sodium reduction. Similarly, increased sugar intake is generally discouraged for all adults, particularly older adults, as it has been linked to various health issues, including obesity and type 2 diabetes, and does not contribute positively to blood pressure management. Thus, reducing sodium is the most critical dietary change for managing hypertension in older adults.
