Abstract

The gut microbiota plays a crucial role in human health and is key to understanding how various factors modulate its composition in older adults, enabling targeted interventions. This study aims to identify how dietary and lifestyle patterns influence older adults' gut microbiota profile, considering the plant-based or animal origin of the dietary protein. A cross-sectional observational study was conducted with older adults aged between 60 and 80. Faecal samples were analyzed to determine gut microbiota composition and assess short-chain fatty acid (SCFA) production. Associations between microbiota profiles, dietary patterns, and metabolic markers were conducted through correlation and

Research summary

The study investigates the influence of dietary protein origin on gut microbiota composition in older adults. This research is relevant as it explores dietary factors that may impact gut health, which is increasingly recognized as a significant aspect of aging and longevity.
