Salt And Your Brain

4 May

Why does a high-sodium diet raise blood pressure in many people? Recent experiments on rats of Canada’s McGill University has found a potential new explanation:  Consuming large amounts of sodium interferes with key brain circuits that are part of a “safety mechanism” that keeps blood pressure within a healthy range.

What happens: The nerve cells release extra vasopressin, a hormone that causes blood vessels to constrict, thus raising blood pressure. The researchers say they don’t know yet whether the same happens in humans.
