The Science
Green beans are low in sodium and provide fiber (2.7g, +10% DV) which supports healthy blood pressure by improving vascular function and reducing arterial stiffness. They also contain magnesium (+6% DV) and potassium (not listed but implied by low sodium), which help relax blood vessels and balance sodium effects. The modest sugar content (+7% DV) is not a concern for blood pressure in typical servings.
Recommendation
Include raw green beans regularly as a side dish or snack, aiming for at least 1 cup per day, while maintaining an overall low-sodium diet.
