Discussion

Narrative review shows dietary interventions enhance gut microbiome and metabolites, suggesting benefits for elderly populations.

Addition of fiber- and polyphenol-rich foods enhances short-chain fatty acid producing bacteria and metabolites.
Interventions resulted in increased propionic acid levels and reduced visceral fat, pointing to beneficial metabolic effects.
Simple dietary changes can produce significant microbiome shifts, especially in elderly and metabolically compromised groups.
Incorporating these foods with caloric restriction preserves microbial diversity and amplifies health benefits.

Meiners et al. (2025) studied this question.
