The effects of the ingestion of powdered coffee containing galactosylsucrose (LS) on defecation, fecal condition and microflora in healthy volunteers were investigated and compared with those of placebo powdered coffee. The subjects were given one pack of placebo powdered coffee (total 16g, without LS) daily for one week (control phase), and not fed any powdered coffee for the next week (blank phase). They were then given one pack of LS-powdered coffee (total 16g, LS 2.2g) daily for two weeks. The fecal microflora on the samples of 8 subjects who were randomly selected from 50 subjects were analyzed.<BR>The number of days with defecation per week was significantly increased by the ingestion of LS-powdered coffee as compared with the non-ingestion in the group although a significant effect was not expressed in comparison with the control phase. The fecal conditions such as volume, shape and hardness feeling were significantly improved by the ingestion of LS-powdered coffee as compared with those of the non-ingestion (p<0.05) and placebo powdered coffee (p<0.05) group (n=19) that also had some slight constipation. The ratio of beneficial microbes, <I>Bifidobacterium</I>, to anaerobes was significantly increased from32.7%to45.9%, respectively, by the LSpowdered coffee ingestion as compared with those of the non-ingestion (p<0.05) and placebo powdered coffee (p<0.05) group. These results demonstrate that the ingestion of powdered coffee (16g) containing galactosylsucrose (2.2g) increases the days with defecation per week, improves the fecal conditions such as volume, shape and hardness feeling and promotes the beneficial proliferation of intestinal microbes in volunteers, in particular, those with slight constipation.
