Abstract
Advances in medicine result in an increase in the age of global population. The percentage of people over 60 years will approximately be duplicated up to 22 between 2015 and 2050, which is associated with a notable rise in age-related complications such as sarcopenia and frailty. The age-related sarcopenia is defined by low muscle strength, and it is considered severe if low muscle strength, low muscle mass, and low physical performance are detected.This condition is associated with poor quality of life, risk of falls, fractures, and higher healthcare costs. Despite the growing interest regarding the treatment of this phenomenon, the lack of adequate knowledge underlying the multifactorial parthenogenesis of age-related sarcopenia hinders the diagnosis of effective therapeutic approaches. In this respect, one of the major solutions would be to recognize the effect of modifiable factors on muscle health during the lifetime. Previous observations indicated that dietary and nutritional factors, beyond other environmental agents across the life course are related to muscle mass and function in the elderly. With respect to the fundamental role of nutrients with antioxidants properties in maintaining many aspects of health, this chapter aims to discuss the association between components of sarcopenia and nutritional status in older adults, and their potential effect on prevention and treatment of age-related sarcopenia.
