Sarcopenia means loss of muscle mass and muscle strength which causes low physical performance and a high risk of mortality on elderly. Dialysis patients with low muscle strength have high mortality rate as well. Adequate nutrition, especially high protein intake (> 1.2g/kg/day) has proven positive effects on sarcopenia. The recommendation of protein intake for preventing sarcopenia is similar to the one for dialysis patients. Encourage dialysis patients to follow the recommendation is needed.
