Polifenole i katechiny: Key Players

Tea leaves are packed poliphenols, a class of antioksydants that included catechins, theaflavines, and thearubigins.

Effect on Insulin Sensitivity and Secretion

Infelin resistance is a hallmark of type 2 diabetes and prediabetes. Tea polyphenols, particularly EGCG, activate AMP-activated protein kinase (AMPK), a master regulator of cellular energy metabolis. AMPK activation increases glucose uptaka in skeletal muscle and adipose tissue, reducles hepatic gluconeogenesis, and enhances fatty acid oksydation.

Green Tea: The Most Studied Variety
