The increasing population of elderly people and prolonged life expectancy paralleled by more health-related problems due to improved medical treatment of chronic disorders provide challenges for the elderly care. With aging, changes in body composition is characterized by an increase of fat mass and a decrease of lean mass. Loss of lean mass can result in deteriorated muscular function that may cause a limitation of mobility, physical performance and increased dependence of assistance from others. To define the age-related loss of skeletal muscle mass the term sarcopenia has been proposed, often defined by using a combination of muscle mass, muscle strength and physical performance. Even though loss of lean mass is a part of the natural aging process, evidence suggests it may be affected by potentially modifiable lifestyle factors such as diet. We aim to assess the associations between diet, nutrients and dietary patterns and sarcopenia in SMCC.
