Deep dives
The controversy surrounding fluoride in drinking water
The debate over fluoride in drinking water is ongoing, with conflicting lawsuits in different areas of the United States. Some believe that any concentration of fluoride in the water is harmful, while others argue that there is not enough fluoride to prevent tooth decay. The issue is complex, and the outcome of these legal battles will determine the future of fluoride in water.
Understanding the benefits of fluoride
Fluoride is known to strengthen teeth and prevent cavities by aiding in the remineralization process. It promotes the construction of hydroxyapatite crystals, which are essential for tooth health. While there are alternative methods to enhance tooth mineralization, fluoride in drinking water remains a low-cost approach to reduce tooth decay. It is important to note that excessive fluoride consumption can be dangerous and disrupt thyroid hormone function.
Examining the potential harms of fluoride in drinking water
The potential harm of fluoride in drinking water depends on the concentration and the amount consumed. High fluoride levels or excessive consumption can affect thyroid hormone function and potentially cause neurotoxicity. The Center for Disease Control recommends a safe level of 0.7 milligrams of fluoride per liter of water. However, individuals should be mindful of their own fluoride intake, taking into account their body weight, and consider filtering tap water if necessary.
Personal choices and filtration options
Individuals can choose their level of concern and approach to fluoride in drinking water based on their own circumstances. Filtering tap water is a viable option for those who are concerned. Various water filters are available on the market, with different price ranges and capabilities. Ultimately, individuals should determine their level of concern and decide whether filtering fluoride is necessary for their specific situation.
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.
