Why is too much salt harmful?
To have good health, the kidneys are concerned with balancing the amount of sodium in the body. Thus, when sodium levels are low, the kidneys are responsible for managing it well and keep it. In contrast, when there is a lot of sodium in the body, the kidneys expel it through the urine. However, if for some reason the kidneys can not eliminate enough sodium, then, of course, it begins to accumulate in the blood. When this happens, and because sodium retains the water, the volume of the blood increases and the heart has to work harder to be able to transport it through the blood vessels. With the increase in the volume of the blood, comes the increase of the pressure on the arteries. And the increase in blood pressure causes other cardiovascular diseases.
