Introduction: The need to generate knowledge has different times in history. Health can be summarized in three models: a) logical-positivist or empirical-analytical , b ) symbolic-interpretative, c ) critical or dialectical . In order to review the alternatives and the model that suits the needs of research in health and environment, an analysis of secondary sources is performed. Development: In health research prevailing positivist logic model and less interpretive symbolic. The critical or dialectical paradigm recognizes health as a complex object with multiple dimensions. Health and environment understanding the historical movement of nature with it socio- ecosystem and forms of artificiality, protective and destructive factors, the relationship between collective and individual processes is necessary. The dialectical approach opens opportunities for triangulation of methods and contributions from diverse cultures to knowledge. Conclusion: The critical or dialectical paradigm allows a comprehensive approach to the problems of health and environment through which is made visible to the biology of the human being is subsumed context and is modified by the environment that is socially determined and historically constructed
