Sugar consumption can negatively affect overall health by contributing to weight gain, increasing the risk of chronic diseases like type 2 diabetes and heart disease, and causing dental issues. High sugar intake can lead to spikes in blood glucose levels, resulting in energy crashes and cravings. Additionally, excessive sugar can impair immune function and promote inflammation. Reducing added sugars in the diet and choosing natural foods can improve health outcomes and help maintain a healthy weight, ultimately enhancing overall well-being.
