Beyond lowering blood pressure, which additional benefits is the DASH diet associated with?

• A. It causes significant weight gain.
• B. It has no effect beyond blood pressure.
• C. It reduces sodium intake only.
• D. It is associated with reductions in systolic and diastolic blood pressure and may improve lipid profile and insulin sensitivity.

Answer: (D)

The DASH pattern improves multiple aspects of cardiovascular and metabolic health, not just blood pressure. It emphasizes fruits, vegetables, low-fat dairy, lean proteins, and whole grains, while providing high amounts of potassium, calcium, magnesium, and fiber and keeping sodium relatively low. This nutrient combination helps relax blood vessels and reduce blood pressure, while also supporting a healthier lipid profile (lower LDL cholesterol and overall cholesterol) and better insulin sensitivity, partly through increased fiber and improved weight management. Because of these broader effects, the diet is associated with both lower blood pressure and improvements in lipids and insulin response. The other options miss these broader benefits: the plan does not cause weight gain, it does have effects beyond BP, and it isn’t limited to just reducing sodium.
