263. Why I Changed My Mind About Hydrogen Water (with Tyler LeBaron)
"In general, the more hydrogen-producing bacteria an individual has, the healthier they are. And we've seen this like with Japanese centenarians. They have higher levels of breath hydrogen naturally out of their breath because you eat fibers, hydrogen gets metabolized, and then you can measure that in their exhaled breath."
LeBaron cited research showing Japanese centenarians have significantly higher levels of hydrogen-producing gut bacteria compared to younger non-centenarians, suggesting a longevity correlation. He noted similar patterns in exercise and inverse patterns in Parkinson's disease, where patients show reduced hydrogen-producing bacteria in fecal analysis.
