Excessive sugar in the diet can have detrimental effects on health, leading to an increased risk of obesity, type 2 diabetes, and cardiovascular diseases. High sugar consumption contributes to weight gain and can cause insulin resistance, resulting in metabolic dysfunction. Additionally, sugary foods can lead to dental issues, including cavities and gum disease. Reducing sugar intake supports weight management, stabilizes blood sugar levels, and promotes overall health. Emphasizing a balanced diet with minimal added sugars is essential for long-term well-being.
