The inventors have found that quercetin and genistein, individually, suppress the expression of some aging-related genes while promoting the expression of other aging-related genes. Therefore, the main objective was to maintain the repressive effect on some aging-related genes that quercetin, genistein, and their glycosides may have, while suppressing the effect of promoting the expression of other aging-related genes. [Solution] The above problem can be solved by combining two or three components selected from the group consisting of component (i): quercetin and / or its glycosides, component (ii): genistein and / or its glycosides, and component (iii): nobiletin and / or its glycosides.
