Advanced Glycation End Products (AGEs)

Advanced Glycation End Products (AGEs) are complex, harmful compounds formed through a non-enzymatic reaction between reducing sugars and proteins, lipids, or nucleic acids. This process, known as the Maillard reaction, occurs naturally within the body as a result of normal metabolism and aging, but it is significantly accelerated by high blood sugar levels. AGEs are also introduced into the body through the diet, particularly from foods cooked at high temperatures, such as those that are grilled, fried, or highly processed.

The accumulation of AGEs in tissues leads to oxidative stress and the activation of pro-inflammatory signaling pathways. These compounds can cross-link with proteins like collagen, leading to vascular stiffness, skin aging, and the progression of chronic diseases such as diabetes and atherosclerosis. Managing AGE levels through dietary choices—such as avoiding ultra-processed foods and utilizing lower-temperature cooking methods—is a critical component of metabolic health and longevity protocols.
