Carmen's daily sodium intake should not exceed milligrams, as the dash eating plan is even more effective when accompanied by a low sodium intake.

The correct answer is 1500 milligrams.
The DASH diet is a diet and lifestyle plan which helps prevent or treat high blood pressure. DASH stands for Dietary Approaches to Stop Hypertension. A DASH diet's main points are to reduce the intake of sodium and increase the intake of important nutrients, such as potassium, calcium and magnesium. This diet has shown to successfully reduce blood pressure even in the first two weeks of implementing it. 
According to the standard DASH diet, a person should not consume more than 2300 mg of sodium daily. If you are on a low-sodium DASH diet, you can only consume up to 1500 mg of sodium daily.
