Etiquetado y rotulación de los alimentos en la prevención del sobrepeso y la obesidad: una revisión sistemática

Abstract

This article reports on a systematic review of articles on food labeling and the prevention of obesity and overweight, in the MEDLINE, EMBASE, Web of Knowledge, Cochrane Library Plus, Food Science and Technology Abstracts, LILACS, and CINAHL databases. The DeCS/MeSH descriptors were obesity and food labeling. 207 articles were retrieved. Using inclusion and exclusion criteria, 14 articles were selected: 11 were on food labeling and its impact on final food product consumption; 2 were on fast food establishments; 1 on sensory attributes as compared to health recommendations; and 2 on follow-up of interventions. Labeling has a positive effect on final food product consumption, in contrast with fast food restaurants. Sensory attributes were more effective than recommendations on the labels. Follow-up of interventions confirmed the long-term effect of the target interventions.

Impact of color-coded and warning nutrition labelling schemes: A systematic review and network meta-analysis

“…Despite the heterogeneity in label types, labelling formats, position, study population, study design, and experimental settings across studies [14,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40], FOPLs were generally considered to have positive effects on guiding consumers in making more healthful food choices,…”

“…For example, women and people with special diet needs or higher perceived nutrition knowledge are more likely to look at FOPLs; the provision of serving size information or percentage of recommended intake may add to consumers' difficulty in understanding FOPLs. Due to the abovementioned reasons, experimental evidence regarding the effectiveness of FOPL in modifying consumers' purchasing or consuming behaviour was mixed [14,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Meta-analyses showed that interpretative colour-coded FOPLs (e.g., TLS) significantly increased consumers' selection of more healthful options from a range of products, as well as decreased calorie and salt content of food purchased [31,41], but no synthesised results for warning labels were available.…”

Propostas governamentais brasileiras de ações de prevenção e controle do sobrepeso e obesidade sob perspectiva municipal

“…As iniciativas identificadas nos municípios do Estado do Rio de Janeiro e em outros estados indicam que a obesidade tem ganhado destaque nas pautas governamentais, e a literatura internacional destaca também algumas ações em curso, desafios e potencialidades, e uma revisão sistemática indica a relevância das políticas regulatórias de alimentos 40 . Além disso, um estudo realizado na Austrália mapeou as iniciativas comunitárias de prevenção da obesidade vigentes, identificando 259, sendo que a maioria abordava ações de alimentação saudável e práticas de atividade física 41 .…”

Intervenciones para el control del sobrepeso y obesidad en niños y adolescentes en el Perú

“…Otra revisión sistemática realizada que evalúo catorce artículos originales, evidenció que el etiquetado y rotulación de alimentos (refrescos, golosinas, productos lácteos, platos de cafetería, productos de marca registrada, comida rápida y ensaladas) logró una disminución en el número de calorías consumidas; aunque ello no fue observado cuando la medida se aplicó en los restaurantes de comida rápida. Los atributos sensoriales visuales (representaciones mediante fotos, figuras, colores, entre otros) fueron más efectivos que las recomendaciones recogidas en el etiquetado de los productos (44) .…”
