Comparative Nutritional Profile of Publicly Procured Foods for School Meals in Federal Schools in Northeastern Brazil Pre- and Post-COVID-19 Pandemic.
Observational study in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
School meals play a critical role in supporting students' biopsychosocial growth, development, learning, academic performance, and the establishment of healthy eating habits. In public institutions, food procurement is conducted through formal public procurement processes. However, emphasizing cost-effectiveness in bidding criteria, such as prioritizing the lowest product price, may inadvertently encourage the acquisition of foods high in critical nutrients. In Brazil, specific guidelines for public school food procurement have been introduced to improve the nutritional quality of foods included in school menus.
objectiveTo evaluate the impact of legislative measures and regulations implemented during the COVID-19 pandemic on the nutritional composition of school meals provided by federal high schools in Rio Grande do Norte, located in northeastern Brazil. It also compared the composition and origin of foods procured before and after the pandemic.
methodsThis is a longitudinal observational panel study conducted across 20 federal schools. Procurement documents from 2019 (pre-pandemic) and 2021 (post-pandemic) were analyzed to assess changes in the nutritional profile of procured foods.
resultsPost-pandemic, the procurement of natural and minimally processed and processed foods increased, representing 73.39% and 10.34%, respectively, of the total approved foods. There was also a 39% reduction in ultra-processed foods compared to 2019, in addition to a reduction in culinary ingredients. Additionally, the proportion of foods containing excessive levels of critical nutrients declined. A significant shift was observed in the origin of procured foods, with a notable increase in the purchase of locally sourced items.
conclusionsThe findings indicate a positive shift in the nutritional quality of foods procured after the COVID-19 pandemic, with a decrease in ultra-processed food purchases and an increase in the procurement of natural and minimally processed options. Nonetheless, the continued presence of ultra-processed foods and items with excessive critical nutrients highlights the need for further improvements in public procurement practices to fully align with nutritional guidelines.
