Hide Arm/Group Description:

Participants received 10g of Oligofructose powdered supplements in sachets each containing 10 g dietary fiber) three times per day. Volunteers were instructed to take the supplement with their main meals.The 8-week supplementation period took place between visits 3 and 4 and included a 2-week run-in period to allow the bowel to adapt to the 30 g of dietary fiber.

Oligofructose: Participants will be asked to consume 30g of oligofructose daily for six weeks after a 2-week run-in.

Participants received 10g of Cellulose powdered supplements in sachets each containing 10 g dietary fiber) three times per day. Volunteers were instructed to take the supplement with their main meals. Maltodextrin was added to the cellulose supplement. The 8-week supplementation period took place between visits 3 and 4 and included a 2-week run-in period to allow the bowel to adapt to the 30 g of dietary fiber.

Placebo: Participants will be asked to consume 3 doses (a total of 30g dietary fibres) of the placebo product daily for six weeks after a 2-week run-in
