The long-term effects of a high-sugar diet can be detrimental to overall health. Regular excessive sugar intake is associated with increased risks of obesity, type 2 diabetes, and cardiovascular diseases. It can lead to insulin resistance and metabolic syndrome. Moreover, high-sugar diets can negatively impact mental health, contributing to mood disorders and cognitive decline. Additionally, sugary foods often displace nutrient-dense options, exacerbating nutrient deficiencies. Maintaining a balanced diet low in added sugars is vital for long-term health benefits.
