Eating too much sugar may affect more than your weight. It could also influence how your body ages.
One reason involves a biological process called glycation, in which sugars react with proteins and other molecules, contributing to the formation of advanced glycation end products (AGEs).
Over time, the accumulation of these compounds can affect the structure and function of important proteins, including collagen, which helps maintain skin firmness and elasticity.
Research has linked excessive AGE accumulation with tissue aging and several chronic health conditions.
However, glycation is a natural process, and eating sugar doesn’t automatically mean your skin will age prematurely. Overall diet, blood glucose regulation, sun exposure, and genetics also play important roles.
The takeaway: Healthy aging isn’t about eliminating every sweet treat. It’s about maintaining balanced nutrition, managing added sugar intake, and building sustainable habits that support long-term health.
