High sugar diets can negatively affect mental health by contributing to mood swings, anxiety, and depression. Excessive sugar intake may lead to fluctuations in blood glucose levels, resulting in irritability and energy crashes. Studies indicate that high sugar consumption is linked with increased risks of mental health disorders. Moreover, a diet heavy in sugar can adversely affect brain function and potentially lead to cognitive decline. Maintaining a balanced diet with low sugar intake supports not only physical health but also mental wellness.
