Can your gut influence how your brain ages?
Research into the Gut–Brain Axis suggests the connection between digestive health and brain function is stronger than many people realize.
Your gut microbiome communicates with the brain through multiple pathways, including:
• the vagus nerve
• immune signaling
• metabolic compounds produced by gut bacteria
Because of this connection, scientists are studying how gut health may relate to mood, cognition, and long-term brain health.
This post is the first in our Gut–Brain Series, where we’ll explore emerging science about the powerful relationship between the gut and brain.
