Un informe reciente de Greenpeace España advierte sobre los riesgos de calentar alimentos en envases de plástico, incluso los etiquetados como "aptos para microondas". El estudio, basado en la revisión de 24 investigaciones científicas, revela que el calentamiento libera cientos de miles de micro y nanoplásticos, así como sustancias químicas peligrosas, en los alimentos. Se detectaron entre 326.000 y más de medio millón de partículas liberadas en cinco minutos, una cifra superior a otros métodos de calentamiento. Materiales como el polipropileno y el poliestireno liberan aditivos químicos como bisfenoles, ftalatos y PFAS, relacionados con problemas de salud. Greenpeace denuncia la falta de regulación de estas sustancias en envases alimentarios y alerta sobre la exposición de los consumidores a este "cóctel" de microplásticos y químicos.
