What else can cause dementia?
Salt is been around for thousands of years. Ancient people used salt to preserve food.
In the recent years, salt is generally used to flavor food. But consuming too much of it can cause health problems.
For instance, a previous study found that eating salty foods is associated with dementia.
Dementia is a mental condition that is characterized by the decrease of numerous mental abilities. The most common condition is Alzheimer’s disease.
The decline in mental ability often causes interference of a person’s daily activity.
The excessive salt intake often found to be a predictor of high blood pressure. But the previous study found an interesting fact.
Dr. Constantino Iadecola, one of the authors shared the result. “We discovered that mice fed a high-salt diet developed dementia even when blood pressure did not rise,” said Iadecola.
“This was surprising since, in humans, the deleterious effects of salt on cognition were attributed to hypertension,” Iadecola added.
When the researchers lowered the amount of salt in the food intake, the mice cognitive functioning returned to normal.
How does salt cause dementia?
The researchers believed that the effect was the result of inflammation in the brain’s blood vessel’s delicate lining.
The inflammation is also the result of a signal from the gut to the brain.
Due to the irregularity in the brain, the mice were less capable of paying attention to novel objects in the cage.
What is interesting is that the amount of salt intake administered to those mice was equivalent to human consumption.
Most people eat salty foods. In fact, about 90% of people in America consume 2,300 mg of salt every day.
The study provides an important clue. Eating salty foods may not only cause hypertension but also dementia.
Most of the time, memory loss is hard to cure. So you better be cautious about your eating habit. Avoid health problems by regulating your salt intake.
