Effects of Lactobacillus Beverage Containing Galactosylsucrose on Defecation in Healthy Female Students with Constipation Tendencies

Abstract

A lactobacillus beverage containing galactosylsucrose (LS) was ingested by healthy female students with constipation tendencies, and its influence on the defecation and fecal conditions were investigated. The test was conducted in five periodical stages. First, the subjects were allowed to ingest a lactobacillus beverage free of LS everyday for a week (Control period), and then for the next one week, the subjects were not allowed to ingest any lactobacillus beverages. Following the washout period, the subjects were allowed to ingest a lactobacillus beverage containing LS (2.5g) everyday for continuous two weeks (LS1W and LS2W periods), and then for the next one week, the subjects were not allowed to ingest any lactobacillus beverages. During the LS ingestion periods, defecation times and days are increased significantly (p<0.05) and fecal form are also improved significantly (p<0.05) in comparison with the control period.
