A high-fiber diet combined with advanced age (centenarian status) establishes a distinct gut microbiota architecture characterized by increased Roseburia and Ruminococcaceae, which is associated with health and longevity.

For older adults aiming to support longevity, incorporating a high-fiber diet rich in legumes, cereals, and vegetables may help cultivate a gut microbiota profile associated with centenarians. This involves increasing the intake of fiber-rich foods to potentially boost beneficial bacteria like Roseburia and Ruminococcaceae.

ModerateSupportsMEDIUM confidence
The age and high-fiber diet were concomitant with changes in the gut microbiota of centenarians, suggesting that age and high-fiber diet can establish a new structurally balanced architecture of gut microbiota that may benefit the health of centenarians.
