Then there's something about Heart Rate Variability (HRV), the vagus nerve, parasympathetic nervous system, and gut biome all being connected. I can measure one of those relatively easily with a chest strap. It seems like the only thing we do know at this point is that we don't know anything. This is an interesting TEDx talk from Eran Segal "What is the best diet for humans?": https://www.youtube.com/watch?v=0z03xkwFbw4 https://www.youtube.com/watch?v=0z03xkwFbw4 My current conjecture / conspiracy theory / understanding includes: * Bacteria near the roots of plants generate electricity. * Plants grow faster in electrified soil. * Electrical brain stimulation can enhance brain function. * There are processes and interactions happening in our gut that we really don't understand yet. * Many ubiquitous things in our environment wreak havoc on our gut biomes (e.g. chlorine, emulsifiers). * There may be more to establishing and maintaining a healthy gut biome than simply consuming foods rich in pre/probiotics. The right kind of exercise and stress may play essential role in keeping it all humming along.
