Sarcopenia
Protein intake and physical activity are important stimuli for muscle protein synthesis. A number of expert groups have proposed an increase in dietary protein recommendations for older age groups to 1.0-1.2 g/kg body weight per day.
Key nutrient supplementation in older adults is of interest in the prevention of sarcopenia and frailty, since it is a simple, low-cost treatment approach without major side effects.
Cat food
Protein content between cat foods can vary anywhere from a low protein content of 26% to a content as high as 50% or above. The National Research Council (NRC) recommends protein content for cat diets is to be around 20% for adult maintenance and 21.3% for growth and reproduction The Association of American Feed Control Officials (AAFCO) recommendations however suggest a higher protein level of 26% for adult maintenance and 30% for growth and reproduction.
