          Abstract

          ABSTRACT Objective: Analyze the content of the main messages of the world food guides, identifying the approach regarding the food processing level. Methods: This qualitative exploratory study was conducted through documentary research based on analyzing the main messages of 96 consumption guides selected from the database provided by the Food and Agriculture Organization of the United Nations. The unit of analysis consisted of segments of the main messages whose content was scrutinized using the document analysis technique. Recommendations that referred to food processing were identified after repeated readings. Data were extracted according to the developed protocol, including terms used, consumption guidance, scope of approach, and complementary information (definition, justification, exemplification, and advice on the recommended consumption amount). Results: We identified 21 Food Guides (21.88%) with recommendations related to the food processing level in their main messages, primarily published after 2012 (76.19%). The analyzed guides used terms “highly processed”, “ultra-processed”, “processed”, “minimally processed”, and “non-processed”. Guidelines regarding limiting consumption were primarily used by the guides, and few specified the related food. The messages did not define the terms used. When identified, the justifications were of a nutritional or health nature. Conclusion: We observed a lack of agreement and standardization concerning the terms used, the guidelines for consumption, and the scope of the identified recommendations, with little or no additional information to explain or justify the approach adopted regarding the food processing level.

          RESUMO Objetivo: Analisar o conteúdo das mensagens principais dos guias alimentares mundiais identificando a abordagem quanto ao nível de processamento dos alimentos. Métodos: Estudo exploratório qualitativo, realizado por meio de pesquisa documental, com base na análise das mensagens principais de 96 guias alimentares selecionadas no banco de dados disponibilizado pela Food and Agriculture Organization of the United Nations. A unidade de análise consistiu em segmentos das mensagens principais cujo conteúdo foi analisado através da técnica de análise documental. Após repetidas leituras foram identificadas as recomendações que faziam referência ao processamento dos alimentos. Os dados foram extraídos segundo protocolo desenvolvido, contemplando: termos utilizados; orientação de consumo; abrangência da abordagem; presença de informações complementares (definição; justificativa; exemplificação; e orientação sobre quantidade recomendada de consumo). Resultados: Constatou-se que 21 guias alimentares (21,88%) faziam recomendações relacionadas ao nível de processamento do alimento em suas mensagens principais, a maioria (76,19%) publicado após 2012. Os guias analisados utilizaram os termos: altamente processado, ultraprocessado, processado, minimamente processado e não processado. Orientações referentes à limitação de consumo foram as mais utilizadas pelos guias e poucos especificavam o alimento relacionado. As mensagens não apresentavam definição para os termos utilizados. Quando presentes, as justificativas eram de cunho nutricional ou de saúde. Conclusão: Foi observada falta de consenso e padronização no que se refere aos termos utilizados, às orientações de consumo e à abrangência das recomendações apresentadas, além de pouca ou nenhuma informação complementar capaz de explicar ou justificar a abordagem realizada em relação ao nível de processamento dos alimentos.

              Ultra-processed food intake and risk of cardiovascular disease: prospective cohort study (NutriNet-Santé)

              Abstract Objective To assess the prospective associations between consumption of ultra-processed foods and risk of cardiovascular diseases. Design Population based cohort study. Setting NutriNet-Santé cohort, France 2009-18. Participants 105 159 participants aged at least 18 years. Dietary intakes were collected using repeated 24 hour dietary records (5.7 for each participant on average), designed to register participants’ usual consumption of 3300 food items. These foods were categorised using the NOVA classification according to degree of processing. Main outcome measures Associations between intake of ultra-processed food and overall risk of cardiovascular, coronary heart, and cerebrovascular diseases assessed by multivariable Cox proportional hazard models adjusted for known risk factors. Results During a median follow-up of 5.2 years, intake of ultra-processed food was associated with a higher risk of overall cardiovascular disease (1409 cases; hazard ratio for an absolute increment of 10 in the percentage of ultra-processed foods in the diet 1.12 (95% confidence interval 1.05 to 1.20); P<0.001, 518 208 person years, incidence rates in high consumers of ultra-processed foods (fourth quarter) 277 per 100 000 person years, and in low consumers (first quarter) 242 per 100 000 person years), coronary heart disease risk (665 cases; hazard ratio 1.13 (1.02 to 1.24); P=0.02, 520 319 person years, incidence rates 124 and 109 per 100 000 person years, in the high and low consumers, respectively), and cerebrovascular disease risk (829 cases; hazard ratio 1.11 (1.01 to 1.21); P=0.02, 520 023 person years, incidence rates 163 and 144 per 100 000 person years, in high and low consumers, respectively). These results remained statistically significant after adjustment for several markers of the nutritional quality of the diet (saturated fatty acids, sodium and sugar intakes, dietary fibre, or a healthy dietary pattern derived by principal component analysis) and after a large range of sensitivity analyses. Conclusions In this large observational prospective study, higher consumption of ultra-processed foods was associated with higher risks of cardiovascular, coronary heart, and cerebrovascular diseases. These results need to be confirmed in other populations and settings, and causality remains to be established. Various factors in processing, such as nutritional composition of the final product, additives, contact materials, and neoformed contaminants might play a role in these associations, and further studies are needed to understand better the relative contributions. Meanwhile, public health authorities in several countries have recently started to promote unprocessed or minimally processed foods and to recommend limiting the consumption of ultra-processed foods.
