The impact of sugar on overall health can be detrimental if consumed in excess. High sugar intake is linked to various health issues, including obesity, type 2 diabetes, heart disease, and dental problems. Added sugars provide empty calories without essential nutrients, leading to weight gain and poor dietary choices. Additionally, sugar can cause fluctuations in blood glucose levels, resulting in energy crashes and cravings. Moderating sugar consumption and opting for natural sources can promote better health and reduce the risk of chronic diseases.
