The Claim
Acute ingestion of 20 grams of either fructooligosaccharide or partially hydrolyzed guar gum reduces small intestinal transit by approximately 30% compared to placebo in healthy young adults, as measured by scintigraphy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Consuming 20 grams of fructooligosaccharide or partially hydrolyzed guar gum slows the movement of food through the small intestine by about 30% compared to a placebo in healthy young adults, as measured by scintigraphy.
See the scientific wording
Acute ingestion of 20 grams of either fructooligosaccharide or partially hydrolyzed guar gum reduces small intestinal transit by approximately 30% compared to placebo in healthy young adults, as measured by scintigraphy, indicating a shared effect on slowing nutrient passage through the small intestine.
When these fibers are swallowed, they absorb water and thicken the contents of the small intestine. This thicker mixture resists movement, so the muscles of the intestine push it along more slowly, making food take longer to pass through.
What the research says
1 studyThis study found that eating 20 grams of either of these two fibers slows down how fast food moves through the small intestine by about a quarter to a third, compared to eating a placebo — just like the claim said.
