The fact that healthy people still get depression makes me skeptical of hypotheses like this. If it were as simple as taking probiotics, x and y supplements, and eating healthier, (and brushing teeth more), I think a lot more people would have beaten major depression by now.
Someone else in the thread suggested it's just exercise, sleep, and diet. Yet there are plenty of folks who do these things perfectly and still get depression.
