The Claim

Fructooligosaccharide accelerates gastric emptying, and both fructooligosaccharide and partially hydrolyzed guar gum slow small intestinal transit, demonstrating distinct physiological effects on gastrointestinal transit despite both being classified as soluble fibers.

Source: Acute intake of fructooligosaccharide and partially hydrolyzed guar gum on gastrointestinal transit: A randomized crossover clinical trial.

How it works
1 study reviewed
In plain English

Fructooligosaccharide speeds up the emptying of the stomach, while both fructooligosaccharide and partially hydrolyzed guar gum slow down the movement of food through the small intestine, showing that these two soluble fibers affect digestion differently.

See the scientific wording

Fructooligosaccharide and partially hydrolyzed guar gum exert distinct effects on gastrointestinal transit: FOS accelerates gastric emptying while both fibers slow small intestinal transit, suggesting their physiological impacts are not interchangeable despite both being soluble fibers.

Why this might work

FOS draws water into the stomach, making contents more liquid and speeding up how fast they leave the stomach. Both FOS and PHGG thicken the contents in the small intestine, making it harder for food to move through, which slows down transit. Even though both are fibers, they change the gut environment in different ways.

  1. Study: Acute intake of fructooligosaccharide and partially hydrolyzed guar gum on gastrointestinal transit: A randomized crossover clinical trial.

    This study found that FOS makes food leave the stomach faster than PHGG, but both slow down how fast food moves through the small intestine. So even though they're both types of fiber, they work differently in your gut.
