呼気中水素分析による朝食内容の検討

Abstract

After having investigated the actual situation of the breakfasts of 122 young women, the breath hydrogen (H2) excretion and subjective symptoms were measured during expiration for six hours after the meal intake (the three kinds of examinations meals, A: rice meal, B: bread meal, C: cereals meal) in healthy humans for the purpose of clarifying the effectiveness of the breakfast meal. The subjects of the breath hydrogen analysis were nine young healthy women. The examinations meal A (A) had a greater intake and quantity of dietary fiber than the other test meals, and a stomach colon reflection occurred earlier, and the total breath H2 quantity was significantly higher. The small intestine transit time for A was 145±17 min, B was 297±22 min, and C was 208±18 min. The significant difference was seen between A and B (p＜0. 001), A and C (p＜0. 05), and B and C (p＜0. 05) . The blood sugar was not influenced by the meal. The feeling of hunger of A became stronger than the feeling of a full stomach from 210-225 minutes. However, the feeling of a full stomach of B at the same level as acalories-in disappeared sooner. In other words, the meal with more carbohydrates was able to provide a feeling of a full stomach that lasted for a long time. The A food consisting of soup, three side dishes and rice contains more dietary fiber and produces more H2 , and it is thought that H2 is involved in the removal of the active oxygen. The rice meal for the breakfast is regarded as an effective meal for increasing the breath H2 production.
