Too much salt may trigger depression, study finds

(Web Desk): Did you know that eating too much salt doesn’t just raise your blood pressure—it can also make you feel sad and irritable?

Yes, according to a new study published in the Journal of Immunology, scientists have found that people who consume excessive amounts of salt may begin to exhibit symptoms similar to depression.

This research was conducted on mice, but the findings may also apply to humans. Scientists fed mice high-salt diets for five weeks. Some were given regular food, while others received salt-heavy meals. The mice that consumed more salt became sluggish, withdrawn, and inactive—behaviors similar to those seen in humans suffering from depression.

High salt intake triggers the production of a specific protein in the body called IL-17A. This protein affects the brain and can lead to symptoms such as sadness, irritability, and lack of interest. Interestingly, the mice that did not produce this protein remained cheerful, even on a high-salt diet.

The study also revealed that a particular type of immune cell plays a crucial role in producing IL-17A. When these cells were eliminated, the mice returned to normal behavior, as if their "depression" had been cured.

In our everyday diets—especially in fast food, chips, salty snacks, pickles, and processed foods—salt levels are often excessively high. According to the research, fast foods may contain up to 100 times more salt than homemade meals.

To tackle this issue, precaution is key. We must pay close attention to our daily diets. How? By reducing salt intake—particularly from fast food and packaged products. Instead, opt for fresh, simple, and balanced homemade meals.

If you often feel sad, irritable, or unmotivated, take a closer look at your diet.

This study serves as a reminder that food is not just fuel for the body, but also the foundation of our mental and physical health.

Use salt in moderation—for the sake of both your body and your mind.
