Introduction: The motivation of the study is to understand whether the keywords and keywords plus of articles in the Nutrition area, indexed on the Web of Science, receive appropriate thematic treatment that favors Information Visualization. Objective: to evaluate the quality of information representation in the Web of Science (WoS) database by analyzing the fields author's keywords and keywords plus of articles in the field of Nutrition in Public Health, seeking to observe the use of these terms in the context of information display. Methodology: This is an exploratory study, which seeks to understand the dynamics of information representation in the Nutrition domain in the WoS database. The corpus consists of a set of twenty articles with a high citation index, published in the period from 2006 to 2016. The analysis took place in two stages: in the first, it applied the criteria for evaluating the indexation to the set of terms of that base and, in the second, he used the DeCS vocabulary (Health Sciences Descriptors) as a parameter to find points of intersection between this vocabulary and the representation of information in WoS. Such analysis had as its central point the literary guarantee. Results: both the author's keywords and the keywords plus of the analyzed corpus were able to meet indexation criteria, however aspects of the thematic representation that compromise the visualization of the information were observed. Conclusions: As for the literary guarantee, the result showed that there is no common language between DeCS and WoS terms.
