Andrew Huberman

Feb 1, 2024

Episode description

Welcome to a preview of the 15th Ask Me Anything (AMA) episode, part of Huberman Lab Premium.

Huberman Lab Premium was launched for two main reasons. First, it was launched in order to raise support for the main Huberman Lab podcast — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.

If you're an existing Premium member, you can log in to access the full episode at https://hubermanlab.supercast.com.

If you're not a member, you can join Huberman Lab Premium at https://www.hubermanlab.com/premium to enjoy exclusive content, including monthly Ask Me Anything (AMA) episodes, AMA transcripts, podcast episode transcripts, early access to live events and help advance human scientific research.

Mindsip insights from this episode:

Limit fluoride intake to protect thyroid function

Consuming too much fluoride, either from high concentrations or large volumes of water, is linked to disruptions in thyroid hormone pathways.

Navigate fluoride water debate for informed choices

There are simultaneous lawsuits in the US, one to remove fluoride from drinking water and another demanding its addition due to its absence.

#water

Recognize fluoride as a poison at high concentrations

Huberman shares a personal story of getting violently ill after swallowing fluoride paste at the dentist, illustrating that it is a poison at high concentrations.

Reverse early cavities naturally by promoting hydroxyapatite bonds

It is possible to naturally reverse early-stage cavities that haven't reached the tooth's deep layers by promoting the buildup of natural hydroxyapatite bonds.

Prevent heart disease by managing oral bacteria

Bacteria from the mouth, particularly from gum issues, can enter the bloodstream and are linked to cardiac, metabolic, and even neurologic diseases.

Avoid aggressive oral care to protect your microbiome

Overly aggressive oral hygiene routines, including harsh mouthwashes and whitening, can damage the critical oral microbiome.

Strengthen teeth with fluoride's super bonds

Fluoride integrates into teeth to form bonds that are stronger, but structurally different, than the natural hydroxyapatite bonds.

Filter tap water for drinking, ignore fluoride in cooking water

Consider filtering tap water for drinking, but don't worry about the fluoride in water used for cooking things like pasta or rice.
