I have no trouble at all accepting this. Our gut is loaded with neurons.
To imagine this, consider that when you are feeling happy, they said its like "butterflies in the stomach". Now consider a situation when someone cannot feel this due to fucked up gut. That on situations when you are supposed to feel happy, you are attacked by anxiety instead, which are also a distinct sensation in the gut. Your life will become a nightmare. I've been there myself, thankfully my gut is good now.
On the flip side, there are people out there with super gut, that feel happy no matter what life throws at them. Just a dose of optimism to lighten up the mood.
That's not how science works. If something is proven and reproducible via the scientific method, it must work(used to make verifiable predictions) whether you accept it or not.
