Associations between dietary patterns and sarcopenia: insights from cross-sectional and Mendelian randomization analyses

Background Sarcopenia is defined as a progressive and generalized skeletal muscle disorder characterized by the accelerated loss of muscle mass and function. Current studies have revealed the significant impact of some dietary factors on the development and progression of sarcopenia. However, these studies often focused on single nutrients but little had examined complete dietary strategies. Thus, comprehensive evaluations of diverse dietary factors in larger populations are crucial for effectively adjusting diets to delay sarcopenia progression, enhancing quality of life and independence in the elderly.
