Chicken soup has long been considered anecdotally healthful in Western and Southeast Asian countries. In this study, we examined the effects of a 2-week intake of chicken soup on mood states and of a single and 2-week intake on peripheral blood flow. Thirty healthy volunteers (7 men and 23 women aged 20.5±1.4 years) participated in a randomized, double-blind, placebo-controlled crossover study with 2 weeks treatment and washout periods. They were randomly assigned to two groups, and daily received either chicken soup or placebo soup. Mood states by the Profile ofMood States (POMS) questionnaire and peripheral blood flow by a laser-Doppler blood flow imaging system were assessed before and after each treatment period. On the first day of the treatment periods, the effect of single intake on peripheral blood flow was investigated. The 2-week intake of chicken soup significantly reduced the tension-anxiety (T-A) score compared to the placebo soup (p<0.05). The single intake of chicken soup significantly increased peripheral blood flow as compared with the base value (20 min after intake p<0.01; 25, 30 and 45 min after intake p<0.001) and that of the placebo soup (25, 30 and 60 min after intake p<0.05; 45 min after intake p<0.01). The 2-week intake of chicken soup also significantly increased peripheral blood flow over that of the placebo soup (p<0.001). Chicken soup was considered to have improved mood states such as tension and anxiety and increased peripheral blood flow.
