A new study has found that regularly drinking soft drinks may not only harm physical health but could also negatively affect mental well-being.
Researchers discovered that these sugary beverages disrupt the balance of bacteria in the intestines, potentially increasing the risk of depression.
According to findings published on a medical research platform, daily soft drink consumption was linked to significant changes in gut microbiota — the microorganisms that play a key role in brain function and mood regulation.
The researchers noted that soft drinks contain large amounts of sugar, which can increase certain types of gut bacteria while reducing others. This imbalance may lead to inflammation in the body, which, in turn, can impact mental health and emotional stability.
The study included 405 participants diagnosed with depression and 527 healthy individuals for comparison.
Higher risk observed in women
Results showed that people who consumed soft drinks daily were 8% more likely to develop depression compared to those who did not. Among women, the risk was significantly higher — up to 16%.
Experts emphasized that the association remained even after accounting for factors like body weight and height, suggesting a strong independent link between soft drink consumption and depression risk.
Causation still unclear
However, the study’s authors clarified that the findings do not conclusively prove that soft drinks directly cause depression. Instead, they proposed that individuals already struggling with depression might be more inclined to consume such beverages frequently.
More extensive research is needed to determine whether reducing soft drink intake could actively lower the risk of developing depression, the researchers added.
Health experts recommend limiting the intake of sugary beverages, especially for women, as part of maintaining better mental and physical health. Cutting down on soft drinks and replacing them with water or healthier alternatives may help promote emotional stability and overall well-being.
