Introduction. Nutritional profiling systems (NPS) are mainly used in front-end labeling policies in order to make the purchase and consumption choice conscious and healthy. Objetive. This study systematically reviewed evidence from interventions on the effect of NPS in the front-of- package on food purchases. Materials and methods. A bibliographic search was carried out in electronic sources from Medline, Elsevier, Scielo and Lilacs, of experimental studies and intervention between 2012 and 2022. A total of 14 articles were included in the review. They were analyzed according to the intervention modality used: 4 studies analyzed the effect of NPS in a real purchase situation and 10 evaluated purchase perception/intention. Results. According to the modality of intervention, the 6 studies that analyzed the NPS-warning system, all recorded healthier purchases compared to the control groups. While for the NPS-NutriScore, Health Star Rating and Multiple Traffic Lights were effective in the decision to purchase healthier foods, in 5 of 7 studies for the first NPS, in 4 of 7 for the second and in 4 of 8 for the third, compared with control groups. Conclusions. Findings of this study suggest that NPSs may be effective for healthy purchase choices, even so it is necessary to strengthen the system and policies with nutritional food education campaigns(AU)

Avaliação dos indicadores de aquisição, disponibilidade e adequação nutricional da cesta básica de alimentos brasileira / Assessment of the indicators of purchasing, availability, and nutritional adequacy of the Brazilian basic food basket

Resumo O objetivo deste estudo foi avaliar a evolução dos custos para aquisição da cesta básica associados ao poder aquisitivo do salário mínimo, além de mensurar a disponibilidade per capita nos domicílios brasileiros dos alimentos que compõem a cesta básica. Também foram avaliadas a adequação da composição nutricional e a qualidade da dieta baseada no consumo diário de itens da cesta básica. Os resultados obtidos apontam a existência de períodos de elevação de preços para aquisição dos itens da cesta básica, assim como a incapacidade do salário mínimo para o custeio para tais provisões alimentares. Foi verificado que as dietas baseadas no consumo dos itens da cesta básica apresentam quantidade de energia e sódio superiores às recomendações para indivíduos adultos, além de apresentar quantidades insuficientes de cálcio, potássio e vitamina A. A avaliação da qualidade das dietas apontou baixa quantidade de frutas, vegetais, cereais na dieta composta pelos itens das cestas básicas, sendo constatado excesso energético proveniente de gorduras e açúcar de adição. Diante de tais evidências, recomenda-se revisão da composição das cestas básicas para atendimento de requisitos nutricionais básicos em alimentação para população brasileira.

Abstract The scope of this study was to assess the evolution of costs for purchasing the basic food basket associated with the purchasing power of the minimum wage, besides measuring the availability per capita in Brazilian households of the items comprised in the food basket. Additionally, adequacy of the nutritional composition and diet quality based on daily consumption of food basket items was evaluated. The results obtained indicate the existence of periods of price increase for the acquisition of the food basket items, as well as the inability of the minimum wage to meet the cost of such food supplies. It was verified that the diets based on the consumption of food basket items have a higher calorie and sodium content than the recommendations for adults, as well as insufficient amounts of calcium, potassium, and vitamin A. The evaluation of the quality of the diets indicated low amounts of fruit, vegetables, cereals in the diet consisting of the items of the food baskets, with excess calories from fats and added sugar being verified. In view of such evidence, a review of the composition of the food baskets is recommended in order to meet basic nutritional requirements in food for the Brazilian population.

Food purchase in e-commerce and its relation to food habit of adult women in Incheon and Gyeonggi / 한국영양학회지

PURPOSE: This study examined the food purchases from e-commerce and its relation to eating behaviors or habits in adult women in Incheon and Gyeonggi. METHODS: A total of 410 subjects participated in the questionnaire survey. Food purchases in e-commerce and food habits were compared according to age, marital status, and food purchase status in e-commerce of the subjects. RESULTS: Approximately 88% of the subjects had experience of buying foods by e-commerce; more than 40% of the subjects spent less than 100,000 Won buying foods by e-commerce in the past 6 months. The major purchases were coffee and tea, instant food and frozen food, and water and beverages. The reasons for buying foods in e-commerce were cheaper price, convenience of delivery, and variety of food choices. The main factors considered for purchasing foods in e-commerce were price and quality followed by rapid and accurate delivery, and food label and information. Approximately 70% of the subjects were very satisfied or satisfied with their food purchase in e-commerce, and 96% answered that they were willing to buy food in e-commerce again. The perception on the advantages of food purchases in e-commerce was 3.6 points out of 5 and significantly lower in the over 50s and married group. The subjects with experience and high cost of food purchase in e-commerce showed significantly low scores of dietary behaviors and eating habits, which is undesirable. CONCLUSION: A high percentage of people purchased foods by e-commerce, and they showed undesirable eating habits, especially when the cost of purchasing foods by e-commerce is high. These results showed that purchasing foods in e-commerce may be related to consumers' food habits. Therefore, continuous attention and nutrition guidance for e-commerce consumers are needed.
