Wprowadzenie: Unpacking the Environmental Roots of a Global Epidemic

For decades, thee relentless rise in obesity and type 2 diabetes has been blamed largely on calie- laden diets, sedentary lifestyle, and genetic contributibility. Yet a growing body of rigorous scientific providence to an equally powerful environmental colarr: endocrine- distorting chemicals (EDCs).

Over time, these diruptions cat thee balance toward walt gain and insulin resistance, creating a methync environment ripe for diabetes.
