American scientists have found that a rich-flavored diet not only damages the heart, but can also lead to an ever-increasing disease.
New research by Weill Cornell University of Medicine (New York, USA) has proven the link between high salt diet and dementia group - the fifth leading cause of premature death in the world World Health Organization (WHO).
Initial experiments on mice showed that after a period of changing the eating style, adding more salt, the mice proved less active, more passive in cognitive tests. After only 12 weeks of eating salty, they struggled in games to identify objects and find their way through the maze, even though they had easily passed earlier.

Further research has uncovered a cause: a high-salt diet promotes the accumulation of Tau in the brain. Tau is a toxic protein, its accumulation in the brain has been shown to cause memory loss, most commonly Alzheimer's disease. At the same time, eating salty also causes disorders of cerebrovascular function, narrowing of the arteries in some small blood vessels deep in the brain and preventing nutrients from being transferred between cells.
The symptoms encountered by salty rats were similar to those of early Alzheimer's and other dementia in humans: decreased ability to navigate (lost), learning difficulties and tests. cognitive test .
The results of the study have proved once again that it is time for us to learn to eat lighter. Previously, many studies and health recommendations have warned of the risk of cardiovascular disease, the most common is high blood pressure in people who eat salty foods. According to WHO recommendations, each person should only eat about 5 g of salt per day. Meanwhile, according to the results of the 2015 National Survey of NCDs in Vietnam, 90% of Vietnamese eat up to 10 g of salt per day. However, reducing salt may seem difficult for many people because the richly tasting way of eating seems to be a common practice in many national cuisines.
The group of dementia is also a global health problem that WHO warns is increasing and will become a major burden in the future. More worrisome, despite many research efforts around the world, dementia has no cure.
