Background. Sarcopenia is a disease that primarily affects the elderly, especially women, and is characterized by a gradual loss of muscle and strength. The clinical definition of sarcopenia is defined as a progressive loss of skeletal muscle mass, which carries the risk of physical disability, reduced quality of life and increased mortality.
Results and conclusion. Proper nutrition is essential in both preventing and treating sarcopenia. The intake of total protein and vitamin D, as well as a balanced diet in general, is crucial in the treatment of sarcopenia. It is also indicated that fruit and vegetables, abundant in the Mediterranean and Japanese diets, may also have a protective effect in protecting muscle function and preventing physical disability. Although the research to date has not explained all the causes of sarcopenia, the most important factors that play a significant role in the prevention of sarcopenia therapy have been identified. These are the optimal intake of total protein, including of animal and vegetable origin in appropriate proportions in the amount consistent with needs, and physical activity. In general, eating a balanced diet containing nutrient-rich foods is associated with protection against muscle loss caused by advancing age and physical inactivity.
