A new study published in Cardiovascular Research has revealed that too much salt in your diet may contribute to increased stress levels. In the study, researchers found that mice given a diet high in salt saw an increase in stress hormone levels by 75%. 

Salt intake can increase an individual’s blood pressure 

According to researchers, this information could help in public health policy review regarding salt intake with an expectation that manufacturers can reduce the amount of salt they use in processed food. 

Adults should consume no more than 6 grams of salt per day, although most people often consume 9 grams. This may result in elevated blood pressure, which raises the risk of vascular dementia, heart attacks, and strokes.

Although the effects of high-salt intake on the circulatory system and heart are well understood, more is needed about how it affects people’s behaviors.

Mice, which typically consume a minimal amount of salt, were employed by researchers from the University of Edinburgh to explore this. They were then given a high salt regimen to mimic the salt intake in people.

High salt intake trigger genes in the brain responsible for regulating reaction to stress 

They discovered that the mice’s hormone reaction to environmental stress almost doubled relative to that of mice on a regular diet, in addition to finding that resting levels of stress hormones increased.

Consuming salt boosted the activation of genes in the brain that make the proteins that regulate how the body reacts to stress. But, according to experts, more research is already being done to see whether consuming a lot of salt causes other behavioral changes, including anxiety and violence.

Matthew Bailey, Renal physiology professor at the University of Edinburg’s Center for Cardiovascular Science, said that people are what they consume, so it is crucial to comprehend how eating foods with a lot of salt affects mental health. He explained that the consumption of too much salt affects the heart, blood vessels, and kidneys. Notably, excess salt consumption changes how the brain responds to stress.
