 Not only is most of the public ignorant about the gut biome, most physicians are as well and I agree with your evolving view. My son was diagnosed with abdominal migraines at 11. The neurologist said it would likely morph into regular migraines once he hit puberty, but said “they didn’t quite understand why, only that it was believed to be the interplay of serotonin and sex hormones.” Sure enough that is what happened. The gut impacts the brain without a doubt. 
 It’s funny the researchers that got literally dragged through hell and back by the pharmaceutical companies and establishment media for their data that showed an unmistakable link between autism and the MMR vaccine, actually weren’t studying that at all. The study itself was about connections between gut health and brain disease. They simply accounted for treatments and vaccines in their data, and the connection just emerged while studying something completely different. 

Then the pharmaceutical companies when on full attack and destroyed their reputations and careers. Saying they were crazy anti-vax loons and quacks. Yet in the actual research they don’t even make the claim of causation, they merely pointed out the data, with a huge defensive caveat of “this isn’t proof, we know nothing, but this should probably be investigated.” But that was enough to get publicly “black bagged.” Most likely because pharma knows perfectly well there’s a connection. 
 It’s why science can’t science.
