Research Progress on Senile Sarcopenia and Its Sutritional Intervention

Sarcopenia, an age-associated loss of muscle mass and function, greatly increases the risk of fractures, falls, and death in older adults. The pathogenesis of which is mainly involves motor neuron loss, hormone imbalance, inflammatory factors, and insulin resistance, etc. Supplementing nutrients such as protei, amino acid, n-3, n-6 polyunsaturated fatty acids and vitamin and other nutrients can effectively prevent and treat the sarcopenia. This paper focuses on the pathogenesis and nutritional intervention of sarcopenia to provide a reference for the research of sarcopenia.
