Resumen
Introducción: la obesidad es un rasgo multifactorial determinado por la interacción de factores biológicos, ambientales, psicosociales y político-socioeconómicos. Propósito: el objetivo de esta revisión descriptiva-exploratoria es discutir el papel del consumo de alimentos altamente procesados y de alta palatabilidad (APAP) en la epidemia de la obesidad, así como presentar algunas propuestas para disminuir su ingesta. Argumentos para la discusión: los APAP se caracterizan por ser energéticamente densos, ricos en grasas y azúcares. En su formulación se utiliza una gran cantidad de aditivos industriales para potenciar su sabor, vida útil y la estabilidad de sus componentes. Suelen contener sustancias químicas conocidas como disruptores endocrinos (EDC) que se transfieren de los empaques al alimento, como el bisfenol A y los ftalatos, y afectan distintas vías de señalización hormonal, promoviendo alteraciones en el metabolismo del tejido adiposo y otros sistemas endocrinos. El sobreconsumo de APAP induce a cambios neuroplásticos en el sistema de recompensa y esto aumenta, a la vez, el número de porciones, con la subsecuente acumulación de grasa corporal; además, dicho abuso causa desbalances en la composición del microbioma intestinal (disbiosis) asociados al desarrollo de obesidad. Conclusiones: el sobreconsumo de APAP incrementa el riesgo de obesidad y enfermedades crónicas no transmisibles, máxime si se inicia a edades tempranas. Para contrarrestar esta problemática, se plantea cambiar la estructura de la canasta básica, regular la venta dentro y alrededor de centros educativos, crear mayores impuestos y fortalecer la investigación en obesidad, APAP y EDC.
