Fiber

Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

The 74.7 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the B tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Key Evidence #1
Public scholarly dataCitation signal: 2367
observational

Dietary fiber deprivation, together with a fiber-deprived, mucus-eroding microbiota, promotes greater epithelial access and lethal colitis by the mucosal pathogen, Citrobacter rodentium.

Key Evidence #2
Public scholarly dataCitation signal: 2053
review

This review will focus on dietary fibers, which interact directly with gut microbes and lead to the production of key metabolites such as short-chain fatty acids, and discuss how dietary fiber impacts gut microbial ecology, host physiology, and health.

Key Evidence #3

review

The current knowledge of the impact of fiber and prebiotic consumption on the composition and metabolic function of the human gastrointestinal microbiota is reviewed, including the effects of physiochemical properties of complex carbohydrates, adequate intake

review

A review of the most up to date data concerning dietary fiber and its effects on metabolic health is examined to give a better understanding of how and why dietary fiber may decrease the risk for certain diseases.

[Abstract]: Diet modulates the gut microbiome, and gut microbes, in turn, can impact the immune system. Here, we used two gut microbiota-targeted dietary interventions, plant-based fiber or fermented foods, to determine how each influences the human microbiome

It is found that melanoma patients reporting high fiber (prebiotic) consumption had a better response to checkpoint inhibitor immunotherapy compared with those patients reporting a low-fiber diet, and this finding has clinical implications for patients receivi
