Don't get Sodium confused with salt because table salt is 40% sodium and 60% chloride. Consuming greater than 2300 millimeter of sodium are bad for you. It can cause hypertension(high blood pressure). Untreated hypertension can cause vital organ damage via heart(heart attack, congestive heart failure,atherosclerosis), brain(stroke), kidney(failure), and eyes. The other day I went to Walmart with my mother and we happen to stop by this blood pressure check machine object. I'm not sure if its accurate, but I tried it out and it read that I have PRE HYPERTENSION -_-. Eating 10 servings of fruits and vegetables and 2 or 3 servings of low fat diary products daily can help people lower their blood pressure. Sodium is essential so we do need them in our diet, but just not too much. It helps our fluid balance, muscle contraction, and nerve impulse transmission. According to the Dietary Guidelines for Americans, 2005, the recommended intake of sodium is less than 2300mg per day or 2000-2300mg per day and for people who have high blood pressure, less than 1500mg per day.
