Diabetes, Cardivovascular Risk, andhe the Potential of Cherry Polyphenols

Diabetes mellitus, secularly type 2, imposes a fasival burden cardiovascular health. Dividuals with diabetes face a two - to fourfold increased risk of developert heart disease, stroke, and distriferal vascular disease compared to thee general population. The underlying mechanisms included chronic hyperglycemia, insulin resistance, dislipidemida, hypertension, and a state of persistent -grade dene aximatione stress.
