Diabetes mellitus is a chronic metabolic disorder that facilitates the formation of advanced glycation end products (AGEs), which contribute to oxidative stress, inflammation, and vascular damage, causing complications including nephropathy, neuropathy, and atherosclerosis. AGEs are primarily synthesized through the Maillard reaction, alongside various signaling pathways. Activation of the receptor for AGE (RAGE) triggers inflammatory signaling pathway cascades, exacerbating tissue damage. Phenolic compounds found in plant-based foods, such as quercetin and resveratrol, have shown promise in counteracting AGE-related complications through their antioxidant and anti-inflammatory effects that inhibit AGE formation, reduce oxidative stress, and modulate RAGE signaling, while also enhancing insulin sensitivity and improving glucose homeostasis. Indeed, quercetin can help prevent AGE accumulation and reduce diabetic nephropathy, while resveratrol activates the SIRT1 pathway, improving insulin sensitivity. This review examines the mechanisms through which phenolic compounds mitigate AGE-induced diabetic complications, using computational, in vitro, preclinical, and clinical evidence. This review also explores the synergistic effects of these compounds with conventional antidiabetic drugs, addresses bioavailability challenges, and suggests future research directions. Overall, this review offers a comprehensive understanding of the role of phenolic compounds in managing diabetes, underscoring their potential as complementary agents in diabetes therapy and developing more effective natural treatments.
