Diet is a vital health question for workers. This review of the related literature sought to identify the elements that could contribute to an examination of the topic and help ascertain how it has been approached from a historical perspective. Our bibliographic research was based primarily on the Scientific Electronic Library On-line, from which pertinent articles were selected for analysis, without regard to year of publication. Among other findings, studies on worker health proved scarce; moreover, the few studies that have explored nutrition focus on the Worker's Food Program, primarily from a quantitative perspective and without taking the category of 'work process' into account in their analyses.
