Gut-Health

The vagus nerve carries 80% of gut-to-brain signals — and you can actively strengthen its function through specific practices.

New research maps exactly how bacteria in your mouth reach your brain and contribute to cognitive decline — and the connection is more direct than anyone thought.

Your gut bacteria make butyrate from fiber — but not all fiber works the same way. Here’s what to eat, what to skip, and whether supplements are worth it.

The rise, fall, and resurrection of a drug designed to block gum disease bacteria in the brain tells you everything about where Alzheimer’s research is heading.

A compound your gut bacteria make from fiber literally changes which genes your brain expresses — and the effect compounds over time.

New research reveals your oral health may predict cognitive decline — through pathways most doctors and dentists never discuss.

The same bacteria behind your gum disease were found in Alzheimer’s brains — and a pharmaceutical company is now developing drugs to block their toxic enzymes.

Your mouth isn’t just where digestion begins — it’s an active signaling hub that talks to your brain through nerves, metabolites, and immune sensors you didn’t know you had.

Your mouth is the starting point of a pathway that reaches your brain — and most people have no idea it exists.

Your gut bacteria produce a compound called butyrate that directly affects brain chemistry. Here is how it works and what you can eat to boost it.

A pharmaceutical company is running clinical trials on a drug that blocks toxins from gum disease bacteria found in Alzheimer’s brains — and the implications go far beyond the drug itself.

New evidence suggests gum disease may contribute to Parkinson’s through systemic inflammation and gut-brain axis disruption.
