What dietary approach is recommended for managing hypertension in older adults?

The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is specifically designed to combat high blood pressure, making it the optimal dietary approach for managing hypertension, particularly in older adults. This diet emphasizes the consumption of fruits, vegetables, whole grains, lean proteins, and low-fat dairy, while reducing sodium intake.

The rationale behind the effectiveness of the DASH diet lies in its nutritional composition. The high levels of potassium, magnesium, calcium, and fiber found in the foods promoted by this diet are known to support cardiovascular health and help lower blood pressure. Additionally, the DASH diet tends to limit processed foods, which are often high in sodium and unhealthy fats, both of which can negatively impact blood pressure levels.

In contrast, while the ketogenic and paleo diets have their benefits, they do not specifically target hypertension in the same direct way that the DASH diet does. The intermittent fasting approach focuses more on when to eat rather than on the specific health benefits associated with the types of foods consumed, making it less tailored for hypertension management in older adults. Therefore, the DASH diet stands out as the most appropriate dietary strategy to effectively manage hypertension in this population.
