Interesting indeed. The article's assumption is that an individual's current microbiome is the optimal state and that preventing it from returning to that state is "potentially harmful". I think this is where I take issue. The last ten years of data shows that the Western diet has completely reconfigured our gut bacteria and that most people's stomachs are probably out of whack to some degree. Preventing it from returning to that state is probably a good thing. That being said, I do find it interesting that probiotics use is more or a less an unquantifiable shot in the dark. What's the right amount to take of each kind of bacteria? Do some people need more of a certain kind, less of another? I feel like we treat it like a panacea when it obviously is not.
