Abstract

Typical Japanese style meals are considered to have good compositions from their nutritional viewpoints, and the life longevity of Japanese could be attributed to a high composition of dietary fiber. Because of insufficient dietary fiber intake, various health problems could be observed in many countries including Japan. Thus, it is recommended that, even in Japanese-style meals, higher amounts of dietary fibers should be taken daily. Different types of dietary fibers are contained in various foods, and some of them may be effective than others to regulate systemic hormone levels as well as their secretion from the digestive tract. Irritable bowel syndrome (IBS) is a functional disorder accompanied with symptoms such as diarrhea and constipation without any pathological change of the digestive tract 1). Various stresses make the syndrome more serious, so that the quality of life may be lowered 2-4). Recently, the number of IBS patients in Japan is increasing 5), especially in young people 6). The main morbid state of IBS is considered to be in an abnormal relationship between the brain and intestine 7, 8). Serotonin (5-hydroxytryptamine: 5-HT), which is distributed both in the brain and intestine, is known to take part in this relationship 8, 9). A number of methods to create IBS model in rats by restraint stress have been reported 10-12). This restraint stress may lead to abnormal fecal excretion due to stimulation of intestinal movement 10-12). The quantity and frequency of fecal excretion were observed as markers of abnormal movement of the digestive tract 10, 11). Serotonin might be involved in the stress-induced alteration of intestinal movement 7-9). Young barley leaf powder (YBLP) is rich in dietary fibers and it has been known as a component material of “AOJIRU, green juice”. There are many papers on effects
