Consideration of a New Form of Hydrolysed Beef Powder as a Source of High-Quality Protein for Elderly. [Consideraciones Sobre un Nuevo Hidrolizado en Polvo Extraído desde la Carne de Vacuno Como fuente de Proteínas de Alta Calidad para los Ancianos].

Fernando Naclerio



An active lifestyle together with optimal nutrition is essential for preserving independent living and quality of life as people ageing. The minimum recommended daily intake for protein (0.8 g/kg) has been considered insufficient for supporting muscle growth and development in young and maintaining muscle mass in adults. Particularly older adults need a higher amount of daily protein intake (~1.0 to 1.2 g/kg or higher in more active elderly people) for maintaining muscle health because of the “anabolic resistance condition” in aged muscle. The quality of protein is essential to promoting muscle mass accretion and health. Beef is a high-quality protein source rich in essential amino acids, essential, fatty acid and micronutrients that is now available as a hydrolysed powder. Recent studies suggested the potential benefits of integrating this novelty form of beef into a regular diet for improving nutrition in athletes or elderly affected by the anabolic resistance condition or those suffering from difficulties in chewing or swallowing.


Un estilo de vida activo acompañado de una nutrición adecuada es esencial para preservar la independencia funcional y la calidad con el envejecimiento. La cantidad mínima diaria recomendada de proteínas (0.8 g/kg) ha sido considerada insuficiente para apoyar el crecimiento y desarrollo muscular en personas jóvenes, así como para mantener la masa muscular en los adultos. Particularmente, los adultos mayores necesitan cantidades diarias mas altas de proteínas (~1.2 a 1.2 g/kg o mas en personas mayores activas) para mantener la integridad muscular debido a la “situación de resistencia al anabolismo” del musculo envejecido. La carne de vacuno es una fuente de proteínas de alta calidad, rica en aminoácidos esenciales, ácidos grasos y micronutrientes que hoy en día esta disponible en un formato de polvo hidrolizado. Estudios recientes, sugieren que la integración de esta nueva forma de carne de vacuno en la dieta puede ser beneficioso para mejorar la nutrición en deportistas o en personas mayores afectadas por la condición de resistencia anabólica o en aquellas personas que sufren de dificultadas para masticar y tragar alimentos.
