Many everyday foods and beverages can contribute to worsening depression symptoms through blood sugar crashes, inflammation, or disruption of brain chemistry. Ultra-processed items like fast food, sugary snacks, sodas, and refined carbs often lead to mood swings and fatigue, while excess caffeine in energy drinks can heighten anxiety, and alcohol acts as a depressant that deepens lows over time. Although some people report short-term anxiety relief from nicotine, long-term use and withdrawal frequently exacerbate depression.
