The document introduces the "Health Field Concept" which provides a framework for analyzing and understanding the health field by dividing it into four main elements: human biology, environment, lifestyle, and health care organization. These elements were identified by examining the causes of sickness and death in Canada. The concept aims to organize the many different pieces of the health field into a simple and logical pattern to help analyze health problems and determine where to focus efforts to improve health outcomes. It also shifts focus to the three elements of human biology, environment, and lifestyle - which are the main underlying causes of current health issues - rather than just focusing on the healthcare system.
