Why is sodium so bad for you? Get this. The average American eats about 3,400 milligrams sodium a day, but the recommended amount for a healthy person is 2,300 milligrams a day. For people with high blood pressure or diabetes, and anyone who is age 51 or older, the daily recommendation is 1,500 milligrams of sodium. However, most people are consuming double what they need in terms of salt.
For most people, a high sodium diet can lead to retaining fluid. And for some sensitive people, retaining fluid can lead to higher blood pressure, which puts someone at higher risk of stroke, heart disease and kidney disease. Whenever you have a high blood pressure, it causes your heart to have to work a lot harder and it can cause damage to blood vessels and the heart muscle itself. Your body is constantly trying to reach an equally librium throughout the course of just one day. If you retain more water then you actually need, your heart is working overtime to expel this via your kidneys. This is why consuming more salt then you actually need can lead to higher blood pressure, which in turn, can exasperate heart problems.
