Salt, also known as sodium chloride, adds flavor to food and is used as a preservative, binder and stabilizer. Our body needs very little sodium to conduct nerve impulses, contract and relax muscles, and maintain proper water and mineral balance. Too much sodium is associated with high blood pressure, heart disease, and stroke. Recommended limits are one teaspoon a day, but since 90% of adults will develop high blood pressure at some point in their lives, some advocates are suggesting to lower the limit to ⅔ teaspoon per day.3
