According to data from the World Health Organization (WHO), 5 percent of adults worldwide suffer from depression.
Experts are exploring effective strategies for treating depression, including diet.
Evidence suggests that following a healthy diet and avoiding foods like junk food can help reduce the risk of depression.
A recent study published in the Journal of Immunology looked at the link between a high-salt diet and depression-like symptoms.
They found that people who eat a high-salt diet develop depression-like symptoms and that this may stimulate a chemical called the cytokine IL-17A, which is harmful.
Experts believe that these findings open up the field of research into better potential treatments for depression in the future.
