Hypertension and salt intake are thought to be closely linked, as regions of the world where salt is consumed in the largest quantities appear to suffer from hypertension the most. The reason that salt causes hypertension is that it increases blood volume. This puts additional stress and strain on veins and arteries in the body, and leads to high blood pressure. It has been shown that people with high blood pressure who can reduce salt intake can achieve a reduction in blood pressure that’s similar to the effects of taking medication.As with many dietary issues, salt should be consumed in moderation, but not eliminated completely. Hypertension and salt are linked, but sodium also performs a number of essential functions. For example, salt is used in the body to help keep blood pressure at a constant level, but only if it isn’t consumed in large quantities. It is thought that a daily allowance of 2400 mg is the maximum that should be consumed, although less is advisable.
