The new food classification: theory, practice and difficulties.

Abstract:

:The objective of this work was to present the theory, propose the practice and evaluate the difficulties of the new food classification system that was presented in the second edition of the Dietary Guidelines for the Brazilian Population. The questionnaire used included a list of 30 foods divided into four groups: in natura or minimally processed foods (I), culinary ingredients (C), processed foods (P) and ultra-processed foods (U). The participants categorized the foods before and after a mini-course. The correct classification score in the Global Assessment (C, I, U, P) was significantly higher after the mini-course (Median = 23) than before the mini-course (Median = 13) (Wilcoxon Signal Test; z = -7.33; p = 0.000; Cliff's Delta δ = 0.96). The low percentage of correct answers before the mini-course justifies the wide dissemination of the theme and the need for more similar courses for students, professionals and the general population. :O objetivo desse trabalho foi expor a teoria, propor a prática e avaliar as dificuldades da nova classificação dos alimentos, apresentada na segunda edição do Guia Alimentar para a População Brasileira. Foi utilizado um questionário com uma lista de 30 alimentos divididos em quatro grupos: alimentos in natura ou minimamente processados (I), ingredientes culinários (C), processados (P) e ultraprocessados (U). Os participantes classificaram os alimentos antes e depois de um minicurso. O escore de classificações corretas na avaliação Global (C, I, U, P) foi significativamente maior depois (Mediana = 23) que antes do minicurso (Mediana = 13) (Teste dos Sinais de Wilcoxon; z = -7,33; p = 0,000; Delta de Cliff δ = 0,96). O baixo percentual de acertos antes do minicurso entre os participantes justifica ampla divulgação do tema e mais ações como essa para estudantes, profissionais e para a população em geral.
