Abstract

Objective: To summarize the different indexes most frequently used to evaluate the quality of diets, as well as the dietary assessment methods used for scoring, pointing out their advantages and disadvantages. Methods: We performed a literature search, with no date restriction, on primary indexed sources and in the databases SciELO, PubMed, Medline, Lilacs, Dedalus and ILSI Web of Knowledge. The keywords used were diet (ary) quality, diet (ary) patterns, diet quality index, Mediterranean diet and nutrition. Then, the cited references were reviewed, classifying the information by index. Results: The most widely indexes used are Diet Quality Index, Healthy Eating Index and Alternative Mediterranean Diet Score, using the food frequency questionnaire or a combination of the 24-hour recall and food (s) record (s). Conclusion: The determination of feeding patterns through indices is a relatively easy process; however, to have confidence in the results is necessary to know the biases that each index and instrument has, as well as its construction and punctuation.
