HUERTA,, Sagrario Lobato; BUCIO-PACHECO,, Marcos  and  VIZCAINO,, Raúl Villegas. Obesity and environmental pollution: paradigms and scientific revolutions. Salud(i)Ciencia [online]. 2021, vol.24, n.6, pp.293-302. ISSN 1667-8682.  http://dx.doi.org/10.21840/siic/166281.

Kuhn in 1962 establishes the revolutionary character of science: "new scientific theories are not born by verification or falsification, but by substitution." The objective of this review was to analyze the ideas and paradigms through which studies on obesity and its relationship with environmental pollutants, diet and epigenetics have passed, in order to illustrate the current situation of this object of study. Articles were managed in December 2020 from the Web of Science. The strategy was Obesity AND (pollution OR contamination) in the Title field, AND (epigenetic* OR obesity OR food OR nutrition OR diet) in the Themes field. 654 articles were obtained: 577 original investigations and 77 reviews. The documents were exported in BibTeXformat to be quantitatively analyzed with the Bibliometrix program. For the qualitative analysis, review articles were selected in whose titles, keywords and/or abstract, carried the word paradigm*, identifying 19 who underwent content analysis. From 1980 to 2020, four periods were recognized, the first and third are classified as normal science; the second and the fourth, crisis of knowledge or revolution. The evolution of the studies has been differentiated. First, the central theme was environmental pollution and secondarily, obesity. For the second and third period, the epigenetics related to environmental pollution and that associated with obesity are investigated separately and at present, causal relationships between environmental pollutants and obesity, nutrients and epigenetics are hypothesized.

Keywords : science; knowledge; research; obesity; environmental pollution; epigenetic; nutrition.
