A new study published in Scientific Reports has found a strong link between high sugar intake and depression — and the results are alarming. Tracking over 8,000 adults for five years, researchers discovered that men who consumed more than 67 grams of sugar per day were 23% more likely to develop depression compared to those who ate less than 40 grams.
The findings suggest that sugar doesn’t just harm your body — it deeply affects your brain chemistry too. When you eat sugar, it triggers a quick dopamine rush — the brain’s feel-good signal — followed by a steep crash. Over time, this rollercoaster disrupts mood regulation, increases inflammation in the brain, and alters neurotransmitters like serotonin, all of which can contribute to anxiety and depressive symptoms.
Doctors now warn that refined sugars found in processed foods and drinks may silently fuel emotional instability, fatigue, and mood swings. Reducing added sugars and replacing them with natural alternatives like fruit, honey, or dark chocolate could help stabilize energy levels and improve overall mental health.
