Until now, we all have a general view about salt’s act that it is highly responsible for causing the symptoms of high blood pressure or hypertension. Now new research suggests something else. It suggests that high intake of salts could lead to the degeneration of the brains too. A new study published in the journal of Nature Neuroscience expressed that excessive intake of salts in the form of high salt diets can bring cognitive decline. However, to your respite its negative effects can be reversed. The study is also helpful in suggesting the methods to reverse its effects.
The Key Focus Of The Study
We had earlier studies on human too, which focused a link between high salt intake and brain health. And this time, this latest study is concentrated to show some important parameters which are responsible for causing degenerative mental conditions with a consumption of high salt in mice.
In the latest study, the mice were fed with normal amount of salt in their diets for 8 to 16 times. The activity and behavior of these mice were observed over a period of 8-12 weeks. And they were seen with a decline in their mental ability and cognition. They had issues with making differences between new and familiar objects. They found it difficult to move through the mazes, and they were unable to erect their nests too. These factors were key to identify the mouse behavior in context with the external world.
If the whole behavior is translated to the human world, this would be reckoned as a severe impairment of cognition or dementia. This is what believes the lead researcher of the study, Costantino Iadecola at Weill Cornell Medical College in New York City. As is with humans, the same mental decline could result in memory problems, and lack of orientation resulting in an incapability of performing a range of daily tasks.
The Amount Of Salt Intake By The Americans
There is not an exact estimation about what amount of salt do the Americans take as most of their salt diets comprise processed foods or restaurant foods. However, as much as salt the mice were fed by the researchers, the typical American diets seem to contain 5-6 times of those amounts of salt consumed by the mice. Therefore, the study is inappropriate in establishing the exact amount of salt taken by them.
However, the study proved that either of the two diets with lower or higher levels of salt is associated with cognition impairment.
At the same time, this study proves its efficacy to make a positive change in the medication process for any patients if they have hypertension or not.
If a higher salt intake has already done a greater damage to the health, there are still ways for you to reverse its effects.
The study showed that once the mice were introduced back to the normal diet, they received back their cognition as before. So, it suggests that if you can curtail your salt intake, all the ill effects of high salt intake can be reversed back. At the same time, preventing too much salt response to the brain could help prevent dementia.
