ANTISTRESS COMPOSITION AND FOOD AND DRINK CONTAINING THE SAME

摘要

An antistress composition of the invention contains ?-aminobutyric acid and a nucleic acid-related compound as active ingredients and it preferably contains ?-aminobutyric acid and the nucleic acid-related compound in a mass ratio of 1:0.0001 to 1:0.1. The nucleic acid-related compound is preferably at least one type selected from the group consisting of uracil, uridine, uridylic acid (UMP), uridine 5'-diphosphate (UDP), uridine 5'-triphosphate (UTP), adenine, adenosine, adenylic acid (AMP), adenosine 5'-diphosphate (ADP), adenosine 5'-triphosphate (ATP), inosine, inosinic acid (IMP), inosine 5'-diphosphate (IDP), inosine 5'-triphosphate (ITP), deoxyuridine, deoxyuridylic acid (dUMP), deoxyuridine 5'-diphosphate (dUDP), deoxyuridine 5'-triphosphate (dUTP), deoxyadenosine, deoxyadenylic acid (dAMP), deoxyadenosine 5'-diphosphate (dADP), deoxyadenosine 5'-triphosphate (dATP), deoxyinosine, deoxyinosinic acid (dIMP), deoxyinosine 5'-diphosphate (dIDP), deoxyinosine 5'-triphosphate (dITP), xanthin and salts thereof. The antistress composition of the invention efficiently suppresses/decreases mental fatigue by oral intake, can be expected to have an effect of preventing/improving health disorder caused by the mental fatigue and can be easily formulated into various foods and drinks.
