Un estudio aparecido en el "American Journal of Epidemiology" no ha encontrado relación entre los patrones alimentarios y el riesgo del cáncer de colon, lo que parece sugerir que basta con mantener un peso adecuado para prevenir este tipo de cáncer, señalan investigadores del Albert Einstein College of Medicine, de Nueva York.
Estudiaron los hábitos dietéticos y el desarrollo del citado tumor en más de 61.000 mujeres suecas durante un período de 10 años.
Clasificaron a las participantes en tres grupos en función de su dieta: saludable (rica en frita, verdura, pescado, ave, cereales y baja en productos lácteos), occidental (carne roja y procesada, dulces y alta en lácteos) y de bebedor (que refleja un alto consumo de alcohol).
Los resultados sugieren que bajas cantidades de alimentos considerados saludables pueden estar asociadas a un mayor riesgo de cáncer colorrectal y que la dieta sana parece ejercer un efecto protector en mujeres jóvenes. Pero en líneas generales, la asunción de que la dieta sana implica menor riesgo de cáncer es un tema que los autores consideran "mucho más complejo de lo que se piensa", y esa asociación no se confirma en la nueva investigación.
