A nurse is planning dietary education for a patient newly diagnosed with hypertension, Considering evidence-based dietary approaches, which diet should the nurse recommend to best manage the patient's blood pressure?

A. While some weight loss may help reduce blood pressure, high-protein, low-carb diets are not specifically recommended for hypertension. They may also be high in saturated fats, which can negatively affect cardiovascular health. B. Diets high in saturated fats and refined sugars are associated with weight gain, dyslipidemia, and increased cardiovascular risk. This would likely worsen hypertension, not manage it. C. Ketogenic diets may reduce weight in some individuals, but their high fat content (especially saturated fats) and low emphasis on fruits and vegetables make them less suitable for long-term blood pressure management. They are not evidence-based for hypertension control. D. The DASH (Dietary Approaches to Stop Hypertension) diet is evidence-based and specifically designed to lower blood pressure. It emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy, while reducing sodium, saturated fat, and added sugars. The high potassium, magnesium, and calcium content helps dilate blood vessels and reduce blood pressure, making it the most effective dietary intervention for hypertension.
