Modulation of Aging Diseases via RAGE Targets: A Dietary Intervention Review

With the acceleration of global population aging, effective strategies for the prevention and management of aging-related diseases have become increasingly urgent. The receptor for advanced glycation end products (RAGE), a pattern recognition receptor of the immunoglobulin superfamily, plays a central regulatory role in the pathogenesis of chronic conditions such as diabetes and Alzheimer's disease. By binding to a wide range of ligands (e.g., advanced glycation end products, amyloid beta), RAGE activates key inflammatory and stress-related signaling pathways, including NF-κB and MAPK, positioning it as a critical therapeutic target. This review systematically examines RAGE-ligand interactions and their downstream signaling cascades, and proposes targeted intervention strategies. Special emphasis is placed on the regulatory potential of dietary bioactive compounds, such as polyphenols, polysaccharides, and terpenoids, highlighting the distinct advantages of functional foods in anti-aging applications. In line with the World Health Organization's concept of "preventive aging," dietary-based approaches offer a long-term, safe, and integrative means of providing both nutritional support and disease prevention. This review provides a theoretical foundation for the development of RAGE-targeted dietary interventions and supports a paradigm shift from medical treatment to nutritional prevention in anti-aging strategies.
