look at CYP2D6 gene polymorphism and it's effect on enzymes and it's existence in many more parts of the body than at first expected, (brain, etc), here's someone smarter than me replying to my stabs in the dark on reddit; "Enzymes are proteins that catalyze (speed up) reactions and consequently are involved in nearly every physiological process. You make a great point with the microbiota-brain interaction (also known as the gut-brain axis). We're starting to look at things like depression as a function of the gut-brain axis and consequently need to start looking to diet and antibiotics as a function of depression.
