Twentyfour healthy adults and 21 female college students ingested from 1to 3 cups of jelly per day considering degrees of constipation. Inthe healthy adults group, frequency of defecation and fecal volumewere increased by the agar-agar jelly (3 cups / day) ingestioncompared with non-ingestion period or the control period of a cupof gelatin jelly given (p > 0.01). Furthermore the agar effectswhich stimulates the defecation were observed in the healthy femalecollege students. Other bowel habits (smell, hardness and shape)were also improved in the agar-ingestion period compared with thenon-ingestion period.
