Problem to be solved. To provide an agent for increasing fatty acid content in a living body which accelerates generation of fatty acid in a living body to increase the total fatty acid amount in a living body, an agent for increasing highly unsaturated fatty acid content in a living body which accelerates generation of highly unsaturated fatty acid in a living body to increase the amount of highly unsaturated fatty acid in a living body, a modifier of fatty acid composition in a living body which accelerates generation of highly unsaturated fatty acid in a living body to increase the amount of highly unsaturated fatty acid, and modifies fatty acid composition in a living body, and an expression promoter of highly unsaturated fatty acid synthetic gene which accelerates expression of a highly unsaturated fatty acid synthetic gene in a living body to increase the expression level of the gene....
