A diet rich in salt is harmful to the brain even when the person is not suffering from high blood pressure
The results of a study in laboratory mice showed that a high salinity diet reduces the amount of blood flowing to the brain and the integrity of blood vessels. They also reduce cognitive abilities
The findings, obtained by the researchers and published in Neuroscience, confirm that even before high blood pressure and microbial damage in the brain, the saline intestine sends signals to create the necessary ground for various adverse changes
Response of the immune system
Scientists have observed that people suffering from high salt concentration show an immune response in their small intestine, leading to the expansion of the lymphocytes "Th17" and high level of interleukin 17, which causes damage to the inner layer of blood vessels in the brain
As a result, the amount of blood reaching the brain regions responsible for learning and memory decreases, and the cerebral cortex and hippocampus contract. This gets even when there is no high blood pressure
The researchers point out that when the mice return to natural nutrition or give them drugs that inhibit the signals emanating from the intestine, their mental and cognitive abilities to normal
Based on the results of this study, researchers discovered a way to save blood vessels in the human body from atherosclerosis and rid of cholesterol, which negatively affects the condition of blood vessels
