Potential health risks of excessive sugar intake include obesity, type 2 diabetes, and heart disease. High sugar consumption can lead to increased fat accumulation, particularly around the abdomen, which raises the risk of metabolic syndrome. Additionally, excessive sugar can result in insulin resistance, further exacerbating health issues. It may also contribute to dental problems like cavities and even affect mental health, increasing the likelihood of depression and anxiety. Therefore, it's essential to manage sugar intake for overall well-being.
