To optimize gut health, one should prioritize a wide diversity of plants rather than focusing solely on fiber consumption, in order to nourish the various metabolic interactions (cross-feeding) between bacteria.

The concept of 'cross-feeding' is a well-documented mechanism in gut microbiology, where metabolites produced by certain species serve as nutrients for others, thereby promoting ecosystem resilience (meta-analysis, Nature Reviews Microbiology). Science effectively confirms that diversity in fiber intake is associated with greater microbiota richness, which is linked to better metabolic health markers (observational study, American Gut Project). The assertion that rotating plant sources better supports these interactions is consistent with current dietary diversity recommendations, although the exact impact of increased variety on specific clinical health outcomes remains an active area of research. The advice to gradually add new plants is a prudent and pragmatic approach, avoiding radical changes that could cause transient digestive discomfort. There is no major exaggeration here; the statement remains faithful to current knowledge regarding the complexity and interdependence of the microbiome.
