Resumo
Introdução: Os sistemas alimentares são um dos principais contribuintes para os impactos ambientais globais, incluindo emissões de gases de efeito estufa, uso excessivo de água e degradação do solo. Objetivo: Diante desse cenário, o objetivo deste estudo foi analisar o impacto ambiental dos alimentos servidos em refeições escolares de escolas públicas de municípios do litoral da Paraíba, Brasil, utilizando indicadores de sustentabilidade como as pegadas de carbono, hídrica e ecológica. Métodos: A pesquisa foi baseada em dados secundários presentes nos processos licitatórios de aquisição de alimentos do Programa Nacional de Alimentação Escolar (PNAE) de 2022, e focou na quantificação dos impactos per capita associados aos alimentos adquiridos para as refeições escolares. Resultados: Os resultados indicaram que os grupos alimentares "Carnes e Vísceras" e "Aves e Ovos" apresentaram os maiores impactos ambientais, com os maiores valores nas pegadas de carbono, hídrica e ecológica. Em contraste, alimentos de origem vegetal, como leguminosas, cereais e hortaliças, demonstraram menor impacto. Discussão: Dessa forma, os resultados sugerem que restringir o consumo de carnes e alimentos processados, aliada ao aumento de opções vegetais e minimamente processadas, pode reduzir significativamente o impacto ambiental das refeições escolares ao mesmo tempo que contribui para a segurança alimentar e nutricional dos estudantes. Conclusão: Portanto, adotar práticas alimentares mais sustentáveis, alinhadas às diretrizes do PNAE na elaboração dos cardápios, é essencial para promover a saúde dos estudantes e a preservação ambiental, e aprimorar políticas públicas de alimentação e nutrição, contribuindo para os Objetivos de Desenvolvimento Sustentável (ODS).
