BRS5(KC2) - Polyphenol & Plant-Diversity Input Sufficiency

1. Ambition

Maintain microbiome-active polyphenol exposure and plant-input diversity so microbial ecological turnover and biotransformation capacity remain resilient.

2. Shared Biological Pool

• Microbiome-active polyphenols ← berries, green tea, cocoa, pomegranate
• Plant-diversity inputs ← herbs, spices, legumes, whole grains

3. Biological Importance

Polyphenol-rich, diverse plant inputs shape ecological selection pressures and the potential for beneficial metabolite generation [Wastyk et al., 2021; Schleupner and Carmichael, 2022; Singh et al., 2022]. When plant diversity and polyphenol exposure are chronically narrow, ecological redundancy and metabolite-production capacity decline.
