Abstract

sarcopenia is defined as a syndrome characterized by progressive and generalized loss of muscle mass and strength. The main cause of sarcopenia is the alteration of protein metabolism, in which the proteolytic processes are not accompanied by an appropriate protein synthesis and muscle cells lose progressively the sensitivity to the anabolic stimulus. The most rational approach to delay the progression of sarcopenia and counteract the anabolic resistance is proper nutrition. Meat contains biologically active compounds, such as creatine, carnitine, Conjugated Linoleic Acid (CLA) which have significant impacts upon human protein metabolism.we performed a narrative literature review to evaluate the till-now evidence regarding: 1. adequate intake of meat in elderly as a topic for prevention of sarcopenia; 2. the correct intake of biologically active compounds contain in meat, which have significant impacts upon human protein metabolism and so have beneficial effects on prevention of sarcopenia. This review included 62 eligible studies.the results demonstrated that in elderly the optimum diet therapy for the sarcopenia prevention and treatment, which must aim at achieving specific metabolic goals, must recommend the consumption of 113 g of meat (220 kcal; 30 g protein) five time a week.in a varied and balanced diet, for preventing sarcopenia, it is recommended to assume meat 4-5 times a week (white meat 2 times per week, lean red meat less than 2 times per week, processed meat less than 1 time per week), as suggested in the diet pyramid for elderly.Introducción: la sarcopenia se define como un síndrome caracterizado por la pérdida progresiva y generalizada de la masa muscular y de la fuerza. La principal causa de la sarcopenia es la alteración del metabolismo de las proteínas, en la que los procesos proteolíticos no van acompañados de una síntesis de proteínas y células musculares adecuadas, con lo que se pierde progresivamente la sensibilidad al estímulo anabólico. El enfoque más racional para retrasar la progresión de la sarcopenia y contrarrestar la resistencia anabólica es una nutrición adecuada. La carne contiene compuestos biológicamente activos, tales como creatina, carnitina y ácido linoleico conjugado (CLA) que tienen impactos significativos sobre el metabolismo de la proteína humana. Métodos: se realizó una revisión de la literatura narrativa para evaluar la evidencia hasta ahora, en relación con: 1. ingesta adecuada de carne en ancianos como prevención de la sarcopenia; 2. la ingesta correcta de compuestos biológicamente activos que contiene la carne, que tienen impactos significativos sobre el metabolismo de la proteína humana y para así obtener efectos beneficiosos en la prevención de la sarcopenia. Esta revisión incluyó 62 estudios elegibles. Resultados: los resultados demostraron que en personas de edad avanzada la terapia óptima con dieta para la prevención y tratamiento de la sarcopenia, que debe apuntar al logro de los objetivos metabólicos específicos, debe recomendar el consumo de 113 g de carne (220 kcal; 30 g de proteínas) cinco veces a la semana. Conclusión: en una dieta variada y equilibrada, para prevenir la sarcopenia, se recomienda consumir la carne 4-5 veces a la semana (carne blanca 2 veces por semana, carne roja magra menos de 2 veces por semana, carne procesada menos de 1 vez por semana), como se sugiere en la pirámide de la dieta para personas mayores.
