Polifenole i diabetic Inflammation: A Commondissive Guidee to Dietary Strategies

Diabetes mellitus, a metabolic disorder defined byuststent hyperglycemia, drids systemic facmation that akcelesations complications including ding cardiovascular disease, neuropathy, and nefropathy. This chronic effimatory state, often termed metaflammation, originates from metabolic surplus and creats a vicious cycle that bessets insulin resistance ance and betacell dysfunction.

Understanding Polyphenols: Classification andd Properties
