Un año después, esa respuesta se asoció con mayor aumento de grasa corporal e IMC.","fuente":"sciencedaily","fuenteNombre":"ScienceDaily","color":"#0b6ea8","autor":"","url":"https://www.sciencedaily.com/releases/2026/11/261101010549.htm","imagen":"/hoy/portada/c06e9f74904784e3","tema":"salud","subtemas":["ultraprocesados","obesidad infantil","sistema de recompensa cerebral","alimentación infantil","neurociencia"],"entidades":["USC"],"formato":"dato","entretenimiento":false,"pubTs":"2026-11-04T01:00:13.000Z","indexTs":"2026-11-04T04:33:01.247Z","hash":"9f9e75d35a2c26f75c5d7d4fe0f77b6695c74ac349d0345656a024073486df04","tsa":{"time":"Nov  4 04:33:15 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"normal","registro":"hallazgo","porQueImporta":"La muestra es chica, de solo 46 chicos, así que el estudio muestra una asociación y no prueba que los ultraprocesados causen el aumento de peso. Aun así, aparece un dato útil: el cerebro infantil en desarrollo podría estar aprendiendo a responder con más ansias a los alimentos de cajita. Para una familia de acá, eso cambia la mirada sobre la merienda y las golosinas, porque la decisión no es solo de fuerza de voluntad. El límite del trabajo es que no sigue a los chicos por años y no separa otros factores de la vida cotidiana.","quienFirma":"University of Southern California (USC)","confianza":"revisado","consulta":null},"sello":{"hash":"9f9e75d35a2c26f75c5d7d4fe0f77b6695c74ac349d0345656a024073486df04","sello":"7144ab07a392145d692a7d1071902390350a2e09f0c3126ad4f8e42b6b31da69","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6611192,"aleatorio":"16fd3d89322febc3be7989709cc6464e4448d93aba1b5585fd1c0ca0afc93dea","tiempo":"2026-11-04T04:33:00.000Z"},"nist":{"cadena":2,"pulso":2012529,"salida":"ADE47727AF4A30BDF9B08FFEE9E7965A3470710B94ED14CD2DC6027A2920AD711FE95EBC9BCE100738BE9741E35689E8C439353FAF75243D1027D7AB1C1D64D5","tiempo":"2026-11-04T04:31:00.000Z"},"noAntes":"2026-11-04T04:33:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  4 04:33:15 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Kids who eat more ultra-processed foods show a troubling brain response","descripcion":"A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's reward system when viewing tempting foods like cookies and French fries. These heightened brain responses were linked to greater increases in body fat and body mass index (BMI) one year later, suggesting that the brain's sensitivity to food cues may help explain why ultra-processed diets are associated with obesity.","pubDate":"Tue, 03 Nov 2026 20:00:13 EST","url":"https://www.sciencedaily.com/releases/2026/11/261101010549.htm"},"indexado":"2026-11-04T04:33:01.247Z"}}
