Abstract
Advanced glycation end products (AGEs) are reactive compounds formed through non-enzymatic glycation in a process known as the Maillard reaction. While humans produce AGEs endogenously, these compounds can also enter the body through dietary sources, food preparation methods, and exposure to agricultural and food-related chemicals. AGEs can accumulate within cells and impair cellular function. In addition, when AGEs bind to receptors for advanced glycation end products (RAGE), they activate intracellular signaling pathways that promote the generation of reactive oxygen species (ROS), mitochondrial dysfunction, and inflammation. Sustained AGE-RAGE signaling drives chronic inflammation contributing to the development of various ailments, including neurodegenerative diseases. This review examines AGE formation, metabolism, and accumulation, with an emphasis on dietary sources as modifiable contributors to AGE-RAGE mediated pathology. We highlight the need for further research on dietary AGE restriction as a potential strategy to prevent or slow the progression of neurodegenerative and neuroinflammatory disorders.
