What is the most important dietary guideline for a client with hypertension?

• A. Four servings of dairy
• B. Five servings of vegetables
• C. Nine servings of fruit
• D. Two servings of whole grains

Answer: (B)

The most important dietary guideline for a client with hypertension emphasizes the intake of five servings of vegetables. A diet rich in vegetables plays a crucial role in managing blood pressure due to the high levels of potassium, fiber, and various phytonutrients found in these foods. Potassium is especially significant because it helps to counteract the blood pressure-raising effects of sodium and aids in vascular function. Vegetables are also low in calories and can contribute to overall heart health, making them an essential component of dietary approaches for individuals with hypertension.

While other options, such as servings of dairy, fruit, or whole grains, may also contribute to a balanced and healthy diet, the emphasis on multiple servings of vegetables specifically aligns with dietary recommendations like the DASH (Dietary Approaches to Stop Hypertension) diet, which is designed to lower blood pressure through nutritional strategies. This particular emphasis makes the guideline of five servings of vegetables the most relevant for managing hypertension effectively.
