American scientists at the University of Delaware were able to prove that the damage to the organs and tissues in the body are possible even in a healthy person, in the absence of signs Hypertension.
If you do not develop high blood pressure from an excess of salty foods, you can still impair the health, damaging the arteries, heart, kidneys and even the brain - according to new research.
Scientists have conducted research and found that the high sodium content in food harms organs and tissues even those who are conditionally considered "salt tolerant". It turns out that a large amount of sodium salt in the diet can cause a violation of endothelial function, the inner shell of the arteries.
Endothelial cells participate in a number of processes, including blood clotting and immune function. Scientists have warned that a high salt content in food can also increase the rigidity of blood vessels, making them less elastic.
"The high sodium content in the diet can cause left ventricular hypertrophy, an increase in muscle tissue that makes up the wall of the main pumping chamber of the heart" - said one of the study's authors, David Edwards, associate professor of kinesiology and applied physiology at the University of Delaware.
"As soon as the wall of the heart chamber are getting fatter, they lose their elasticity, and eventually become incapable of pumping blood as well as a healthy heart" - he explained.
According to a study published March 17 in the Journal of the American College of Cardiology, high salt intake can impair renal function, as well as influence on the sympathetic nervous system and cause a reaction.
Another study author William Farquhar, a professor of the Department of Kinesiology and Applied Physiology at the University, said: "Chronically high sodium content in food can" sensitize "sympathetic neurons of the brain and cause a response to this stimulus, which may lead, including a reduction skeletal muscle.
"Again, even if the blood pressure does not increase, chronic hypersensitivity sympathetic nervous system can adversely affect the authorities", - he said in his report.
