You may think you’re making healthy food choices most of the time. But the truth is, the foods you eat could contain unexpectedly high amounts of sodium.

Most adults need only about 1,500 mg of sodium a day for top-notch nerve and muscle function. More than about 2,300 mg (less than six grams of salt) can lead to high blood pressure, putting you at risk for heart and kidney disease and stroke.

Take our quiz to find out how much sodium is really in your food and see why  making a few simple changes can dramatically reduce the sodium in your daily diet.
