Prebiotics

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

The 54.4 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.

[Abstract]: The health benefits of dietary fiber have long been appreciated. Higher intakes of dietary fiber are linked to less cardiovascular disease and fiber plays a role in gut health, with many effective laxatives actually isolated fiber sources. Higher i

Key Evidence #2

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

Key Evidence #3

review

There is general support for antidepressant and anxiolytic effects of probiotics, but the pooled effects were reduced by the paucity of trials with clinical samples and additional randomized clinical trials with psychiatric samples are necessary fully to evalu

Public scholarly dataCitation signal: 427
observational

Overall, 8 weeks of probiotic supplements to subjects with MDD resulted in an improvement in BDI score compared with placebo whereas no significant effect of prebiotic supplementation was seen.

Public scholarly dataCitation signal: 361
observational

It is shown that particular non-digestible dietary carbohydrates have enormous potential for modifying the gut microbiota, but these modifications occur at the level of individual strains and species and are not easily predicted a priori.

Public scholarly dataCitation signal: 308
observational

It is shown that lack of prebiotic dietary fiber leads to the development of a hypertensinogenic gut microbiota, hypertension and its complications, and a role for G-protein coupled-receptors (GPCRs) that sense gut metabolites is demonstrated.
