Un elevado consumo de carne roja durante mucho tiempo incrementa el riesgo de desarrollar cáncer de colon, tal como muestra un nuevo estudio publicado en "JAMA" por investigadores de la Sociedad Americana del Cáncer.
Los autores llevaron a cabo el seguimiento de más de 148.000 adultos, de una edad media de 63 años, que completaron varios cuestionarios en 1982 y luego 10 años más tarde acerca de su dieta, práctica de ejercicio, historia médica y otros hábitos de estilo de vida.
En 2001 se habían registrado entre los participantes 1.667 nuevos casos de cáncer colorrectal. El análisis de los datos muestra aquellas personas que comen más carne roja y procesada se enfrentan a un riesgo un 50% mayor de desarrollar el cáncer respecto a aquellos que consumen menos.
El alto consumo de ave y pescado se asoció a una reducción del 25% riesgo de cáncer de colon, aunque no de cáncer de recto.
