Abstract
In Japanese saying, wellness is expressed as "sleep well, eat well, and defecate well". Keeping these three factors does not mean lack of any symptoms, but having positive feelings. In this meaning, these three words may represent health-related quality of life. The author conducted population survey on these three factors, along with major gastrointestinal (GI) symptoms and health-related behaviors. There were significant correlation between three wellness indicators and GI symptoms, and also with willing loss, perceived stress, and regularity of daily life. Meal preference also has correlation with wellness factors and GI symptoms. Namely, daily-life behavior itself may have some impact on wellness and health-related quality of life. Therefore, the author concludes that healthier eating habit itself might be important for human wellness.
