RESUMEN

Embelleciendo la vida se puede alcanzar una tercera edad enriquecedora, edificante y larga. El "adaptismo" es una corriente explicativa de la nutrición y alimentación humana que pretende matizar la vergüenza de la existencia de malnutrición en el siglo xxi con pinceladas lingüísticas tranquilizantes para sus generadores. Las actuales generaciones son el resultado de alternos períodos de hambrunas y plétora, los cuales seleccionaron a los sobrevivientes. Según la hipótesis de la "Programación Fetal" o del "Fenotipo Ahorrador", las enfermedades de la adultez se programan por hormonas y neurotransmisores, durante períodos críticos del desarrollo fetal. Ella centra la atención de los debates sobre el alarmante comportamiento epidemiológico de diabetes, obesidad y cáncer en la actualidad. La prolongación de la esperanza de vida, como resultado de una muy exitosa combinación de un sistema inmune bien preservado, buena capacidad para enfrentar al estrés, estilo de vida apropiado y carga genética, va acompañada de la prevención de enfermedades no transmisibles. Las acciones para ello deben comenzar antes de la vida intrauterina. La vejez, en si misma, no es un problema sin solución: el problema consiste en la marginación, la enfermedad y la pobreza, que no permiten alcanzar una vida digna en muchas regiones del mundo para este grupo de edad.
