A patient is newly diagnosed with hypertension. The nurse suggests a dietary sodium reduction to help lower blood pressure. What rationale should the nurse share for reducing sodium intake?

"Reduced salt makes food taste less appealing, so you will lose weight, reducing your blood pressure."

"A low-sodium diet has been shown to reduce blood pressure."

"The blood volume will be decreased after a high intake of sodium."

"Salt intake and smoking go together; reducing one helps with the other."
