Does the bacteria in your gut affect how you age?
The trillions of bacteria living in your gut don't just affect digestion — they influence inflammation, immune function, and how your body ages. Studies consistently show that people who age well tend to have more diverse gut microbiomes. Diet, particularly fibre and fermented foods, is one of the most reliable ways to influence this.
