A recent study found that eating a lot of salt can increase stress levels.
Researchers discovered that a high-salt diet increased the levels of a stress hormone by 75% in mice trials.
Adults should consume no more than six grams of salt per day, but most people consume around nine grams.
This can lead to high blood pressure, which increases the risk of vascular dementia, heart attacks, and strokes.
Researchers from the University of Edinburgh used mice, which typically consume very little salt, to investigate how high salt consumption affects human behavior. They were fed a high-salt diet to mimic human salt intake.
They discovered that not only did resting stress hormone levels rise, but the mice’s hormone response to environmental stress was twice as strong as that of mice fed a normal diet.
Salt consumption increased the activation of genes in the brain that produce proteins that regulate how the body responds to stress.
According to experts, the findings should prompt a reconsideration of public health guidelines regarding salt consumption as well as manufacturers’ efforts to reduce salt content in processed foods.
We are what we eat and understanding how high-salt food changes our mental health is an important step to improving wellbeing. We know that eating too much salt damages our heart, blood vessels and kidneys. This study now tells us that high salt in our food also changes the way our brain handles stress.
