How can excessive sugar intake affect health?

Excessive sugar intake can significantly impact health in several detrimental ways. When a person consumes large amounts of sugar, the body receives high levels of empty calories that can contribute to weight gain. These additional calories often come from sugary beverages and processed foods, which can lead to an energy surplus that the body stores as fat, resulting in obesity.

Moreover, high sugar consumption is linked to an increased risk of developing type 2 diabetes. This occurs because elevated sugar intake can lead to insulin resistance, where the body's cells become less responsive to insulin, making it more difficult to regulate blood glucose levels. Over time, this can progress into full-blown diabetes if unmanaged.

Additionally, sugary foods and drinks can harm dental health. The bacteria in the mouth feed on sugar, producing acids that lead to tooth decay and cavities. This repeated cycle of acid production can weaken tooth enamel and cause long-term dental problems.

Thus, the answer identifies critical health issues associated with excessive sugar consumption, making it clear that a high-sugar diet poses various risks to overall well-being.
