Huberman Lab Clips(@HLPClips):Fermented food beat fiber in our own study: - We expected high fiber to give the massive signal. Across the cohort we never saw it. Fiber responses were highly individualized - Six weeks of high fermented food intake raised gut microbiota diversity, and in the industrialized world higher diversity generally tracks with better health - A couple dozen inflammatory markers dropped in stepwise fashion, including interleukin-6 and interleukin-12, with immune cell signaling cascades less activated by the end Dr. Justin Sonnenburg on @hubermanlab
