If this were not so it would violate Physics as we know it, because all things flow both ways. This is a concept that has been questioned by those who correctly point out that most, if not all, physical problems stem from our belief systems, or mind-spirit issues. I have agreed with them wholeheartedly, while at the same time pointing out that the body influences the mind. Dichotomies, opposing concepts, dualism have often troubled people throughout the ages. Masculinity-Femininity polarization, the mind-body connection, and the brain-gut axis are examples of this common conundrum.
The answer is in INTEGRATION, BALANCE, HARMONY, BEAUTY, HOMEOSTASIS. The latter is a synonym of HEALTH.
One of the first clues I found that the gut influences the brain was dissecting the Vagus nerve. I was taught it is a cranial nerve that goes from the brain to the gut. Yet, when examining its constituting neuron tails, researchers found that 1/3 of them go from the brain to the gut, while 2/3 go the other way. After graduating, I reviewed thousands of studies showing how the gut influences the brain; they convinced me that I had not been taught an INTEGRATIVE, BALANCED approach to HEALTH.
This is why I was delighted to find this issue:
