摘要：We recently read, with great interest, the article by Kameda et al. (1). They conducted untargeted metabolomics analysis of whole blood samples of 19 older adults; identified 22 markers for frailty, cognition, and hypomobility; and find the following: 1) Metabolite profiles can efficiently distinguish frailty from nonfrailty; 2) antioxidant ergothioneine is neuroprotective; and 3) oxidative stress may be key to frailty and age-related illnesses. While this study makes a significant contribution to the current understanding of metabolomics and frailty, we have a few concerns. First, in this study, frailty was diagnosed … [↵][1]1To whom correspondence may be addressed.
