New Delhi, Oct 24: Soda and soft drinks, long enjoyed for their sweetness and instant energy boost, may have deeper health consequences than previously believed. Beyond the well-known risks of obesity, diabetes, and heart disease, new research suggests that regular consumption of these beverages may also harm mental health — particularly among women.

A large-scale study published in JAMA Psychiatry has revealed a significant link between sugary drink consumption and depression. The research, which involved 932 adults — including 405 diagnosed with major depressive disorder (MDD) and 527 healthy individuals — found that women who frequently consumed sugary sodas were 17% more likely to develop depression over time.

These women also reported more severe depressive symptoms compared to those who drank fewer sweetened beverages. Interestingly, the connection was less pronounced in men, suggesting that biological or hormonal factors may play a role.

Scientists found that women who consumed high amounts of sugary drinks had elevated levels of a gut bacterium called Eggerthella, previously associated with depression. This finding points to a potential link between soda consumption, gut health, and mood regulation — suggesting that what we drink may influence our emotional balance through changes in the gut microbiome.

Health experts warn that sugary and artificially sweetened beverages can disturb gut bacteria, trigger inflammation, and affect neurotransmitter production, which are essential for maintaining mood stability. Women may be especially vulnerable due to hormonal fluctuations and immune responses that heighten sensitivity to dietary changes.

While researchers emphasize that the study is observational — showing a strong association but not definitive causation — they advise moderation and healthier drink choices.

Simple lifestyle changes, such as cutting down on soda, choosing water or herbal teas, and maintaining a diet rich in fibre, fruits, and probiotics, can help protect both gut and mental health. Regular exercise, stress management, and mindfulness practices can further support emotional well-being.

Experts conclude that small, consistent steps toward reducing sugary drink intake could make a meaningful difference — not just for physical health, but for a more balanced and resilient mind.
