The research was conducted by an American team (Weill Cornell Medical Center). They initially focused on mice, fed with an extremely high-salt diet, equivalent to a very high consumption in humans. Observations show that this excess leads to dysfunction in blood flow to and within the brain, insufficient dilation of blood vessels, and cognitive impairments. The mechanisms involved are complex, involving the immune system originating from the intestine, with an alteration in the production of nitric oxide, important for regulating blood flow and the good health of neurons. According to the journal "Nature Neuroscience," human salt consumption is increasingly high, well above the levels recommended by nutritionists and health authorities. This excess is accompanied by a detrimental effect on the brain, reducing the necessary cerebral blood flow for its proper functioning and thus increasing the risk of developing cognitive disorders, even dementia. Experiments in mice indicate that reducing salt intake restores the situation to normal. These data justify considering a reduction in salt consumption to maintain brain health.
