Advanced glycation end-products (AGEs) derive from a chemical reaction – the Maillard reaction – between reducing sugars and amino compounds during digestion and food processing. In aging individuals, AGEs may be associated with the initiation of inflammatory substances causing further tissue damage and increased disease risk.
AGEs are under preliminary research as possible biomarkers of aging and the development, or worsening, of chronic diseases, such as diabetes, atherosclerosis and Alzheimer's disease. As of 2024, the evidence for AGEs having a pathological role in aging diseases is generally inconsistent or inconclusive, with no causal association demonstrated between foods, AGEs and diseases.
