High-sugar diets can negatively impact children's health by increasing the risk of obesity, Type 2 diabetes, and dental problems. Excessive sugar consumption often leads to poor dietary choices and an increase in caloric intake, which can contribute to weight gain and unhealthy eating habits. Furthermore, high-sugar diets may disrupt energy levels, resulting in mood swings and difficulties in concentration. Educating children about balanced nutrition and promoting healthier snack alternatives can help mitigate these risks and encourage long-term healthy habits.
