What is the main purpose of the DASH diet?

The main purpose of the DASH diet is to reduce hypertension, or high blood pressure. This dietary approach emphasizes the consumption of nutrient-rich foods that are low in sodium and high in potassium, magnesium, and calcium, which are beneficial for heart health. The DASH diet encourages the intake of fruits, vegetables, whole grains, lean proteins, and low-fat dairy products, all of which work together to promote better blood pressure control.

By focusing on foods that are rich in these essential nutrients, the DASH diet effectively helps lower blood pressure and improve overall cardiovascular health. It is supported by various studies showing that following this diet can result in significant reductions in blood pressure, making it a well-regarded recommendation for individuals managing hypertension.

While the other options may have some relevance to the DASH diet, such as weight loss being a potential secondary benefit due to healthier eating habits, the primary focus and research supporting the diet center around its effectiveness in lowering blood pressure.
