The breath hydrogen (H2) excretion and subjective symptoms were measured during expiration for eight hours after a meal intake (used four kinds of examination meals) by healthy humans for the purpose of clarifying the effectiveness of the dietary fiber meal. The subjects of the breath H2 analysis were five or seven young healthy women.The examination meals B and D had a greater intake and quantity of dietary fiber than the A and C test meals, and the breath H2 quantity was significantly higher (p<0.05, p<0.01). The max breath H2 quantity for B was 40.6±17.8ppm (p<0.05), and for D were 38.8±28.3ppm (p<0.01) which were significantly higher than A and C. Each total breath H2 of A, B, C and D was 5463, 7221, 2337 and 6955ppm×min, respectively. The small intestine transit time of A, B, C and D was 334±25, 285±14, 273±32min and 273±26min, respectively. No significant difference was seen between A and B, and C and D. The blood sugar was not influenced by the meals. The cross point of time of while feeling hunger and the feeling of a full stomach of A and B was both of 210min, C was 255min, and D was 255min. The meal with more carbohydrates, like D, was able to provide a feeling of a full stomach that lasted for a long time. The D food consisting of more dietary fiber produced more H2, and it is thought that H2 is involved in the removal of the active oxygen. The dietary fiber rich meal is regarded as an effective meal for increasing the breath H2 production.
